2.8 Powering the USB dongle

The BC660 module can be powered through USB or through external battery power source. To power it

through USB, connect PIN 1 and PIN 2 (and disconnect PIN 2 and PIN 3) on the USB/BATT power jumper

then plug the USB dongle into a USB port on a PC. The USB port provides power to the USB dongle and

BC660 module.

If the BC660 module is to be powered from external battery power source, then connect PIN 2 and PIN 3

(and disconnect PIN 1 and PIN 2) on the USB/BATT power jumper. No need to plug the USB dongle into

USB port on PC since the power is provided through the external battery power source.

You interface with the USB dongle through UART interface. The UART (TXD/RXD) can be connected to any

external device with UART (Tx/Rx) interface such as an Arduino board or any other hardware board

available.

You connect the USB dongle through TXD and RXD, to a USB port in the computer through a USB-to-

UART cable. You can use cable such as this one:

USB TO UART TTL (Wires) Serial Cable (PL2303HX) MCP00102W Programmer Arduino Compatible in

Elecrow bazaar!

Such a cable has multiple colored wired, and you connect them to pins on USB dongle as follows:

White: TXD

Green: RXD
