1. Introduction

This document shows how to use the demo board (MDBT42Q-AT-UART-M) to test function of

MDBT42Q-ATM & MDBT42Q-PATM.

MDBT42Q-AT-UART-M is designed for testing and debugging without building your own

board. The board is only available with MDBT42Q-ATM (chip antenna) module.

MDBT42Q-ATM will be pre-

programmed with Raytac’s AT command firmware. If you don’t

need such pre-programming and is looking for nRF52832 module, please check

MDBT42Q-512KV2 and MDBT42Q-P512KV2.

Please visit our

website

for spec sheet of every module mentioned above.

1.1. Contents of the Set

Each set includes MDBT42Q-AT-UART-M x 1 and mini-USB cable x 1. Please contact us if

the set you receive is not complete.
