1.1 EVK-R4 overview
The EVK-R4 kit is a powerful and easy-to-use tool that simplifies the evaluation of the u-blox SARA-R4 series LTE
Cat M1 / NB1 cellular modules.
The following evaluation kits are available with u-blox SARA-R4 cellular modules:
EVK-R404M evaluation kit is for evaluation of SARA-R404M modules
EVK-R410M evaluation kit is for evaluation of SARA-R410M modules
o EVK-R410M-01B evaluation kit is for the SARA-R410M-01B module product version
o EVK-R410M-02B evaluation kit is for the SARA-R410M-02B module product version
All the evaluation kits are identified herein as the EVK-R4.
See the SARA-R4 series Data Sheet [2] and the SARA-R4 series System Integration Manual [3] for the
features supported by the u-blox SARA-R4 series cellular modules.

EVK-R4 - User Guide
The EVK-R4 is formed by three boards:
The lower one, called EVB-WL3, contains the power supply and other peripherals for the SARA-R4 series
cellular module (SIM card holder, Reset button and Power-on button).
The cellular adapter board, called ADP-R4, contains the SARA-R4 cellular module, the cellular antenna
connector and the USB connector for the cellular module.
The GNSS adapter board, called ADP-GNSS, contains the u-blox GNSS module, the GNSS antenna connector
and the USB connector for the GNSS module.
The boards are connected by means of male header board-to-board connectors provided on the bottom of the
adapter boards and their corresponding female connectors provided on top of the lower board.
The USB interface of the cellular module is available on the native USB connector on the cellular adapter board,
while the other peripherals are available on the dual-in-line male board-to-board connectors provided on the top
layer of the cellular adapter board, which are pin-to-pin compatible to the connectors on the bottom layer of the
adapter board.
The lower board (EVB-WL3) is designed to also be used with other u-blox cellular adapter boards. It contains
additional switches, jumpers, connectors, LEDs and parts that are only partially described in Figure 1 and in this
document, because they are intended for use only with other u-blox cellular modules. It is recommended to
leave any additional connector unconnected, and to leave any additional switch in its default configuration.

CAUTION! IN THE UNLIKELY EVENT OF A FAILURE IN THE INTERNAL PROTECTION CIRCUITRY,
THERE IS A RISK OF AN EXPLOSION WHEN CHARGING A FULLY OR PARTIALLY DISCHARGED
BATTERY. REPLACE THE BATTERY WHEN IT NO LONGER HAS A SUFFICIENT CHARGE FOR UNIT
OPERATION. CONTROL THE BATTERY BEFORE USE IF THE DEVICE HAS NOT BEEN USED FOR AN
EXTENDED PERIOD OF TIME.
