MatrixTable Controller R3

Last crawled date: 4 years ago

This is the revision 3 board for the MatrixTable project. This version has moved to a single MAX7219 matrix/7-segment driver and an ATMega328. The reason for the switch from the ATTint to the ATMega is becaise the Arduino SD library will not work on it.. Aditionally, there is level-shifting circuitry onboard to interface with the MAX7219, because everything else is running at 3.3V but the MAX needs 5V. #Arduino #ATMega328 #ATTint85 #circuit_board #controller #LED #MatrixTable #MatrixTable_controller #microcontroller #table
