Expand 3 click is an accessory board in mikroBUS™ form factor. It includes an 8-channel programmable I/O expander DS2408 that communicates with the target board MCU through a 1-Wire interface (15.3 kbps or 100kbps) The onboard GP SEL jumper allows you to specify the communication pins (either OW1 or OW0, which are in place of the usual AN and PWM pins on mikroBUS). An additional reset line (RST) is also connected. The board is designed to use either a 3.3V or 5V power supply. PIC examples are written for:
- EasyPIC v7 - PIC18F45K22
