Hi Group.
I am working on a simple "Open source" Raduino replacment board: see here:
It will use the Adafuit Clock board:
So will run all devices at 5v.
I hope to have pinouts and dimension exactly the same as the origional so it can be used as a direct drop-in replacement. Or modified for i2c display and other GPIO mods...
Should be cheap (.50c a board, $3 nano, $8 Si5153 board plus a 7805 regulator and a few other bits... I'll try make it both SMD and TH for the capacitors and resistors...
So you can build a cheap easy <$20 Raduino replacment....
Constructive comments and thoughs welcome.
