1 Overview
The u-blox C030 LTE Cat 1, Cat M1, NB-IoT and 2G/3G mbed-enabled IoT starter kit is a versatile
development platform that allows quick prototyping of a variety of applications for low-power Internet
of Things (IoT) devices.
The u-blox C030 boards are delivered in several variants based on the type of u-blox cellular module
employed, such as:
• C030-U201: SARA-U201 HSPA module with 2G fallback
• C030-N211: SARA-N211 NB-IoT (LTE Cat NB1) module
• C030-R410M: SARA-R410M LTE Cat M1 / Cat NB1 module
• C030-R3121: LARA-R3121 LTE Cat 1 single-mode module with GNSS receiver
The u-blox C030 application boards, except C030-R3121, have a u-blox MAX-M8C module or a ZOE
GNSS IC as a concurrent GNSS receiver, thereby enabling straight forward development of locationaware, globally communicating applications.
The u-blox C030 board provides access to a variety of hardware interfaces (10/100 Mb/s Ethernet, 22
GPIOs with SPI, I2C, UART, PWM) through the Arduino™ Uno R3 compatible header connector.
An eUICC (embedded SIM) is integrated on the u-blox C030-U201 / C030-R3121 variants. The eUICC
comes with International Data Roaming Cellular Connectivity Service by JT® JTGlobal (formerly
Jersey Telecom) with 50 MB of data for the period of 90 days, which can be topped up and extended
on demand.
The u-blox C030 board is powered by an Arm® Cortex-M4 based ST® STM32F437VGT Host
microcontroller, which is fully supported by the Arm® Mbed™ platform. The microcontroller has 512 kB
flash, 64 kB RAM, and runs an up-to-96 MHz system clock. The board provides simple USB drag-ndrop programming and ST-Link debug interface for the Host microcontroller. The Arm Mbed platform
provides free software libraries and online tools for professional rapid prototyping. The programming
is done using a standard-based C/C++ SDK. The Arm Mbed compiler also supports full export to
various tool chains, for projects that demand it as they go into production.
The u-blox C030 also works with wide choice of Integrated Development Environments (IDEs)
including but not limited to Arm® Keil®, GCC-based Eclipse IDEs.

The C030 consists of three sections:
• Utility section
The utility section accommodates the components that provide SW debugging / virtual COM port
(ST-Link/CMSIS-DAP) and Ethernet Interface functions. The SW debugging / virtual COM port
functions are executed by the InterfaceMCU via the “Debug USB” interface.
As this section is only needed during the application development and test activities, it could be
physically snapped off from the application section to decrease the size and power consumption.
The utility section is powered up from the “Debug USB” 5V VBus. When the “Debug USB” is not
connected, SW debugging / virtual COM port and Ethernet Interface functions are turned off and
isolated from the Application section.
The “Auxiliary 5V USB” connector on the Utility section could be used to boost the power input to the
application section if the current input from the “Debug USB” 5V Vbus is not sufficient.
• Application section
The application section accommodates the GNSS and cellular modules, a eUICC (Embedded SIM) /
MicroSIM socket, the HostMCU, the battery charging/management and power supply circuitry, the
SD card interface and socket, the Serial USB Sniffer for communication between the HostMCU to the
cellular module and similarly to the InterfaceMCU. The application section also has a temperature
sensor for measuring ambient temperature of the board. Reset and user buttons, configuration
jumpers and User and system status indication LEDs are placed in the application section.
The application section is designed for minimal power consumption. Unutilized circuitries and
sections could be either turned off by software or inhibited electronically.
The Arduino Uno R3 interface on the application section could be used to integrate sensors, actuators
and power/battery supply circuitries as Arduino Shields/expansion daughter PCBs.
The application section could run standalone when the utility and antenna sections are snapped off.
• Antenna section
The C030 PCB has been designed to accommodate GNSS and cellular antennas on-board depending
on the build variant. The C030-N211 antenna section could be snapped off if the orientation of the
C030 is in an enclosure required by the application. Both application and antenna sections have SMA
edge connector footprints. Therefore, by soldering the SMA Edge connectors, the antenna section
can be connected to the application section through adequate 50 Ω RF cables.
The other C030 variants have SMA Jack edge connectors for cellular and GNSS antennas.

2.2.1 Utilization of cellular modem USB sniffer (and programmer)
The C030 cellular modem USB sniffer provides two virtual UART COM channels to the connected USB
master (development PC). The cellular module USB sniffer USB VBUS 5VDC rail powers the
application section of the C030. The virtual COM ports are utilized as follows:
C030-U201 / C030-N211 variants:
• Standard COM port as on the development PC: HostMCU USART1 Tx “printf” channel sniffing.
o HostMCU USART1 Tx is also connected to the InterfaceMCU on the utility section
o HostMCU USART1 Rx is connected to InterfaceMCU on the utility section
o Host HostMCU USART1 Rx can be connected to the cellular modem USB sniffer standard COM
port Tx channel via R137 link (see Table 4). In this case, do one of the following:
▪ The utility section should be powered off (disconnect Debug USB)
▪ Snap-off the utility section
▪ Remove R133 link (see Table 4)
• Enhanced COM port as on the development PC. Two operation modes can be selected by using the
S2 switch (see Figure 12):
1. S2 Position 1: HostMCU USART2 to cellular module communication. Allows direct access to
the cellular module. In this case, implement the following steps:
▪ Connect the R151 link(see Table 4)
▪ Remove the R105 link or set the HostMCU PD_5 port as GPIO input to avoid collision
▪ This mode is only used for SARA-N2 FW Flashing/Programming for C030-N211 variant.
The P3 Jumper should be configured accordingly to utilize this function (see Table 1)
2. S2 Position 2: SARA-N2 module debug log output (GPIO1) with 921,600 b/s 8N1 configuration
for the C030-N211 variant only.
C030-R410M / C030-R3121 variants:
• Standard COM port as on the development PC: HostMCU USART2 Tx “printf” channel sniffing.
o HostMCU USART2 Tx is also connected to the InterfaceMCU on the utility section
o HostMCU USART2 Rx is connected to InterfaceMCU on the Utility section
o Host HostMCU USART2 Rx can be connected to the cellular modem USB sniffer standard COM
port Tx channel via R137 link (see Table 4). In this case, do one of the following:
▪ The utility section should be powered off (disconnect Debug USB)
▪ Snap-off the utility section
▪ Remove R133 link (see Table 4)
• Enhanced COM port as on the development PC. Two operation modes can be selected by using the
S2 switch (see Figure 13):
1. S2 Position 1: Isolation
2. S2 Position 2: HostMCU USART1 to cellular module communication. Allows direct access to
the cellular module. In this case, do one the following:
▪ Remove R105 link
▪ set the HostMCU PA_5 Port as GPIO input to avoid collusion
☞ Enhanced COM port Mode 1 direct access to the cellular module allows using development PC
applications like u-blox m-center, to exercise the cellular module AT command interface bypassing
the C030 HostMCU.
☞ On the R410M / R3121 variants, usage of USART1 and USART2 have been swapped as compared
with the U201 / N211 variants.

2.3 LED indicators
The C030 has a few LEDs to indicate the board status for generic application use. Due to the low power
design of C030, if the C030 is not connected to an external power source or is powered from battery
only, all the LEDs except D3 (User RGB LED) and LED_G3 (GNSS Time Pulse LED) are off.
As the D3 and LED_G3 LEDs are controlled by the application, they can be completely turned off to
save power.

Ethernet LED indicators are powered by 3.3 VDC generated from the Debug USB VBUS, which powers the whole Utility section.
If the Debug USB is not connected to a USB Master (for example, a development PC), the Utility section is powered down, and
therefore the Ethernet LED indicators do not light up.

signal. When the SPI bus on the Arduino Interface is utilized by other SPI slaves on daughter
boards, free Arduino digital IO lines should be utilized for Slave Select signals.
⚠ As the SD card interface and its supply voltage are designed to work with 3.3 VDC, the SD card
socket shall not be used when the Arduino interface IOREF voltage level is set to higher than
3.3 VDC. Such usage could cause a permanent damage and/or a failure to an SD card inserted in
the J2 socket and the C030’s Arduino™ interface level translators. (See R152 and R153 links in
Table 4).

2.8 Power supply options and LiPo battery usage
The C030 can be powered up from several resources, individually or all together. The power supply
usage configurations are provided in Table 7.
#
Connector
Description
1
Debug USB
Uses development PC’s USB 5 VDC VBUS to power up the Utility and Application sections
of the C030. It charges up the LiPo battery if it is connected.
2
Aux 5V USB
Auxiliary USB power input. A USB power supply could be connected to power up only the
Application section of the C030.
It charges up the LiPo battery if it is connected. There is no communication functionality.
3
Serial USB sniffer
Uses Development PC’s USB 5 VDC VBUS to power up only the Application section of the
C030. It charges up the LiPo battery if it is connected. The serial USB sniffer circuitry could
only be powered from its dedicated USB connector.
4
LiPo battery
The C030 Application section could run only from a LiPo Battery connected. If one or many
of the #1, #2, #3 USB connections are available. The LiPo Battery is charged up as well.
5
Arduino™ UNO R3 VIN Pin 8
Arduino™ UNO R3 VIN pin 8 could be used to power up entire the C030 Application section
except serial USB sniffer circuitry. STLink (or CMSIS-DAP when available) feature could be
used through the debug USB. However, the C030 Application section including LiPo Battery
management circuitry is disconnected.
The VIN input voltage should be in the range of 2.5 VDC to 5.5 VDC.
Table 7: C030 power supply options and LiPo battery usage
☞ The C030 could run on a single supply input from #1 debug USB or #3 serial USB sniffer. However,
the cellular module transmission power demand might not be satisfied from these connections.
In such a use case, the C030 might be suffering brownout dues to USB VBUS supply rail cuts due
to USB current limitations. Therefore, either a 5 VDC USB power supply with ~3 ADC capacity
should be connected to the Aux 5V USB connector and/or an adequate LiPo battery, such as a BAK
LP-503759-IS-3, should be connected to the LiPo battery connector. The locations of the power
supply connections are shown in Figure 19. It is recommended to use LiPo battery in conjunction
to the USB connections as high frequency current demands might not be provided by the USB
VBUS rails but the LiPo battery
