12 Connecting QCA4020 to Serial Terminal Through UART
You can use the QCA4020 miniPCIe when mounted on USB adaptor (HAT) with any device that has UART
(Tx/Rx) interface such as a Raspberry PI board, Arduino board or any other hardware board, with UART
interface.
You can also use and connect the
QCA4020 miniPCIe/USB adaptor (HAT)
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 four wires colored as follow:
Red: +5V
White: Tx
Green: Rx
Black: GND
Connect the White cable to UART_TX and Green cable to UART_RX. Also connect the Black cable to the
GND).
As in the picture below, connect UART_TX to SJ2 (PIN2) AND UART_RX to SJ1 (PIN2).
