1. Overview
1.1 Introduction to DVK
The DVK provides a complete solution based on the module. For designers who adopt the module
in their designs, the DVK facilitates their module-based programming and troubleshooting at the
project development stage. The module is welded onto the development board in a manner that is
similar to the surface mount ing of chips. The signals output from the module are transferred to the
development board for secondary development.
NOTE:
In the following sect ions, “module” refers to the ME919Bs-567bN LTE LGA module.
1.2 Setting up DVK
This chapter describes how to set up the DVK to ensure that the module can work normal ly. As
power of the module can be provided from a 12V power adapter or 5V in USB interface, set up
J305’s jumpers in accordance with your power choice. Therefore, there are two powers you can
use in the DVK.

Method 1:
When the power is supplied by a 12V adapter rather than a 5V in USB interface, connect J305’s pin
3 and pin 2, and J605’s pin2 and pin1. The jump wire configuration is showed in F igure 2.

Method 2:
When the power is supplied by a 5V in USB interface rather than a 12V adapter, connect J305’s pin
2 and pin 1, and J605’s pin2 and pin1. The jump wire configurat ion is shown in Figure 4.

1.3 Power-up and Turning on the module
When the MCU on the DVK is power-on, connect J307’s pin2 and pin1 to power the module up.
The jump wire configurat ion is shown in Figure 5.
Figure 5 J307’s Pins
After powering the module up, press and hold the Power_on_off (silk-screen is ON_OFF) button
for more than 0.5s to turn on the module, as is shown in Figure 6.
