Console / UART0 location for MQ1DW

Pro / Dual / MQ-R
#1

Hi. Might be a dumb question, but I’m using a new MPi-MQ1DW:
https://mangopi.org/mangopi_mq

From what I can gather, the OS images are compiled to use uart0 as the console serial connection for the operating system. Where exactly can I find the uart0 pins on the board? Specifically the TX, RX, and ground pins that I’d need to connect a USB-to-TTL adapter so I can see what’s going on.

All of the docs I have found so far describe the board in detail, but lack a visual photo of the actual pins and what goes where. If anyone can help, I’d appreciate it. Thanks in advance.

Here’s the photo from the MangoPi site:

Found the answer finally, so here it is for anyone else:

Bottom row of pins is what we’ll be using for console (labeled P3 on the board).

Pin 1 = ground (black wire)
Pin 7 = TX (white wire, RX to USB port)
Pin 8 = RX (green wire, TX from USB port)

When I refer to green/white wires I’m talking about the USB-TTL adapter I use, linked above. It’s the Adafruit model.

I was not able to power the board via the red wire as it sends 5V @ 500MA, but I was able to power it via a USB-C connection.

Set your serial port for 115200, N81.
