1 OVERVIEW
Arduino is an open-source electronics platform based on easy-to-use hardware and software. The
NuMicro® NuMaker UNO Evaluation Board is an Arduino compatible hardware using NuMicro®
microcontroller (MCU) as the MCU. Its function can be extended with Arduino add-ons. With the
Arduino IDE, users can develop their applications and leverage large number of open source
samples.
Figure 1-1 NuMaker UNO Board
The NuMaker UNO is a specific development tool for NuMicro® NUC131 series by which users
can develop and verify the application program easily. Its purpose is to provide a platform for
development and learning. With ADC, PWM, I²C, SPI, UART and other peripheral functions, user
can set different functions on the NuMaker UNO development kit, or increase the peripheral
functions according to the user needs on the development kit. The NuMaker UNO includes two
portions: NuMaker UNO (an evaluation board) and Nu-Link-Me (Debug Adaptor). With the
NuMaker UNO, users do not need additional ICE or debug equipment.
Figure 1-2 NuMaker UNO Board with Different Add-ons
The NuMaker UNO is pin to pin compatible with Arduino UNO board.
Digital pins provide UART, I2C, LED, INT, and 10-channels PWM. In addition, the extended pins
of MCU NUC131SD2AE provide 24-channels PWM and 6-channels UART. Clock Output (CLKO)
is also available on extra pin.

3 INTRODUCTION TO NUMAKER UNO DEVELOPMENT BOARD
Figure 3-1 and Figure 3-2 show the NuMaker UNO development board, in which the left portion is
called NuMaker UNO target board and the right portion is Debug Adaptor called Nu-Link-Me.
The NuMaker UNO is similar to other development boards. Users can use it to develop and verify
applications to emulate the real behavior. NuMaker UNO can be a real system controller to design
user’s target system. NuMaker UNO is pin to pin compatible with Arduino UNO revision 3. The left
portion is NuMaker UNO target board where the NUC131 series MCU is mounted on. The
NUC131 series provides 24-ch PWM as well as 6-ch UART, and commonly used peripherals
such as Timer, WDT, SPI, I2C and ADC. The NUC131 series also provides CAN communication
interface.
The right portion is the debug adaptor called Nu-Link-Me which connects the USB port from PC to
user’s target system (via the Serial Wired Debug port) and allows users to program and debug
embedded programs on the target hardware. In addition to loading external application, it also
provides a virtual serial port (VCOM) functions. The debug messages through user-friendly NuLink–Me is displayed on the computer screen. For detailed description, please refer to section
3.1.2. The NuMaker UNO supports Arduino IDE, Keil, and IAR. For detailed installation and setup,
please refer to section 4.1.
The NuMaker UNO development board provides the Arduino pin-out definition and extended
connectors for each pin from the NUC131SD2AE MCU. It can be used to connect the application
circuit board. The target board also supports a wide range of power supplies, such as from ICE,
VDD & GND (JP1 & JP2) or from 7V ~ 12V transformer. LED status is for power, I/O, TX, RX and
ICE, as shown in Figure 3-1.

3.1.1 Power Settings
There are three methods to use the NuMaker UNO board to provide power to VDD. The first
method is through the Nu-Link-Me USB interface. This power will go through LDO voltage
regulator to 3.3V, JPR1 can be used to adjust VDD power to 5V or 3.3V. The second method is
through the JP1 on development board to VDD by DC 2.5V ~ 5.5V power supply. The third
method is through transformer (7V ~ 12V) and then the voltage is converted into 5V through
the step-down circuit. Please refer to the table below.

3.1.2 USB Virtual COM Function Setting
SW2: Open the Virtual COM mode for the debug message and supply power to NuMaker

The Virtual COM function can be used for Arduino IDE, Keil and IAR. To enable VCOM
function on Nu-Link Me, turn on all SW2 pins. To enable the UART0 function, turn off pin 2 ~
pin 4 on SW2. Please refer to the table below.

5.1.5 Step 5: Check the Correctness of the VCOM Baud Rate
User needs to check if the virtual serial port baud rate setting is the same as the program
setting. When the program is set to 9600, the virtual serial port monitor will be set as 9600.

Figure 5-6 Serial Monitor
This example uses ADC0 to perform ADC conversion into a digital value which is then displayed
by the virtual serial port out. To set a COM port baud rate and then display the virtual serial
conversion results, use the ADC0 pin connected to VDD or VSS. Then, whether the ADC
conversion result is correct can be displayed.
