Hi
I’ve made a board for the 40pin DIP version of the 4809 processor , really to make it easier to develop stuff rather than using proto boards.
Features are :
- 5v 7805 regulator
- 3v3 regulator
- 2 pots to create analog inputs
- 4 LEDs for digital outputs
- two types of clock circuits for external clock
- 4 push buttons for digital
Inputs - MAX232 interface .
- RC filter stage
- two potential dividers
- two Open collector drivers
- various 5v/0v connections bought out
- all pins bought out labelled with ports and Arduino numbers to align with Mighty CoreX
- serial interface with reset capacitor for programming via Tx/Rx
- 1 pin program connection.
- free areas
- pull up and pull down resistors
I had to get ten of these made , would anyone want to buy bare boards?
