Table 9: Arduino UNO Interface Jumper
The Arduino UNO interface 3.3V power rail is supplied directly by the VDD_3V supply from the AVT9152
module in the evaluation kit.
Jumper J20 provides option to choose the Arduino UNO interface 5V supply source from either supplied by
the ex5V DC power adaptor or the ex3.6V battery. When external battery is selected, jumper
J19 must be installed so that the U10 5V boost converter will be turned on to convert the ex3.6V
battery level to 5V and feed to the Arduino UNO interface.
J20 Jumper Setting
Arduino UNO 5V Supply Source
J20:1-2 ON
Supplied by ex3.6V battery when J19:1-2 ON.
J20:2-3 ON
Supplied by ex5V DC power adaptor.

In order to provide flexible connection to the narrow band cellular IoT network, LTE-M Cat-M1, the AVT9152
evaluation kit comes with OTA reprogrammable eUICC SIM card as part of the kit accessories. Please
refer to the AVT9152 Quick Start Guide for the steps to setup the connection to the backend cloud server.
Please note that the eUICC SIM card may not support network connection in certain countries. In this case,
user can choose their preferred local network provider and obtain a micro SIM card instead.
