I have one of the HiLetgo UNO R3 clones and I'm in the process of building an SDrive Max unit.
The flash programming seems OK and the display works. I've calibrated it and able to see the SDrive software running on it.
I am doing the wiring of an SIO cable to the UNO board and noticed the RX pad and A5 ANALOG IN pad seem connected when I check continuity. Is that correct?
As such, this does not work right now. I am unable to access any of the virtually mounted drives when connected to my 800XL.
Thanks for helping someone who just might be clueless.
