The SIO Modification PCB will allow SDrive-MAX units to function with physical drives or other SIO devices on the SIO chain.
This PCB comes fully populated with resistors, IC and header pins already mounted to the circuit board.
Not for the novice user, you must be comfortable soldering this daughter PCB onto the Arduino UNO as well as connecting the SIO cable correctly and soldering a wire from the daughter board unto the Arduino A5 connection.
PCB is designed with a power switch connector allowing you to select power over SIO or power via external power supply connected to the Arduino UNO.
The daughter board is thanks to the great PCB design work of Steve Boswell if you want to build your own check out his UNO2SIO page.
*Does not include Arduino UNO, only daughter PCB
