1 Overview
WL680 demo board provides a series of peripheral interfaces, including main power supply
interface and UART interfaces for commissioning and software download. You can perform
commissioning after connecting to power supply and serial ports. This document describes only
the commissioning process. For details about software update, please refer to module update
document.

For details about the connection, see 3.4.
3.4 M5X0-PWR Board
The above figure shows an M5X0-PWR board, which supplies 3.8V/0.6A power for the module
and outputs 3.3 V CMOS level TXD and RXD for the communication between the computer and
the module and software update. It is connected to the WL680 demo board through 4-pin cables,
which have been soldered to the power board in a sequence of red, black, yellow, and green at one
end and should be inserted into the socket of the demo board at the other end. There are two pins
on the power board and they can control the power supply of the module.
Among the 4-pin cables:
Green: TXD, output, 2.85 V CMOS level
Yellow: RXD, input, CMOS level, 3.1 V maximum
Black: Ground
Red: VBAT, 3.6 V to 4.3 V, 3.9 V is recommended
Refer to the silk
print label.

If you want to use this power board to commission the module through serial port on a computer,
install a driver for USB to serial (PL2303 Windows Driver). If you want to use an MCU to control
the demo board, you also need to use the 4-pin cables.
3.5 Commissioning
Perform product commissioning directly on a computer through the USB interface. The power
board and demo board are connected as shown in the following figure.
Before the commissioning, you must install the PL2303 Windows Driver. Then, connect the demo
board to a computer as shown in the following figure.
