(I had to mangle the URLs as this is my first post and there's a anti-spam measure configured in this forum..)

Finally got some time to test these boards. I really wish there was a single page "getting started" instruction, because now gathering all the information is quite hard.. Anyway:

I got a cable like this: httpswww.adafruit.com/product/954, it has PL2303 inside it and I've installed the driver.

I tried to understand what's going on here: httptalk2forum.wisen.com.au/topic21.html#p137, but got lost at:

"How about the PIN-OUT and connection to the Whisper Node? Have you connected the Whisper Node TX to the FTDI RX and the Whisper Node RX to the FTDI TX? The serial TX/RX lines need to be inverted."

Could someone post a picture of what needs to be done?

I also have a Arduino Uno, but don't have time to test that out today - not sure if I understand these correctly: httptalk2forum.wisen.com.au/topic23.html#p76 -- a picture would be super helpful.

Sorry for being such a noob here.

I've never done this before but will attempt to help.

Did you find the documentation here: https://bitbucket.org/talk2/whisper-node-avr. You will find the required pin connections as well.

RX of one goes to TX of the other and vice versa for the other line (TX to RX).

RX --- TX
TX --- RX

Looks like a proper FTDI would make this easier.

Best of luck,
Robin

Just complementing the answer, the USB-to-Serial adapter you got seems to have only. You should be able to see the Splash-screen but you would need to "manually" reset the board before upload new code.

Here two options I have been successfully testing lately:
https://www.aliexpress.com/item/MWC-Mul ... 45760.html - The pinout is already correct, just need to align ground-to-ground.

https://www.aliexpress.com/item/Free-Sh ... 89140.html - This one the pinout is not correct, but it's easy to re-arrange it to match the Whisper Node's pinout.

I also use this one: but you'll need to make have a cable or use female-female jumper wires, but the pinout is correct: https://www.aliexpress.com/item/Free-sh ... 18879.html

Apart from inverting TX/RX it shouldn't be too complicated, but I'll try to take a picture and post it here for reference.
