WIP: ATmega644P/1284P Dev Board

This project is still in the making...

A Development Board for the ATmega644P and ATmega1284P microcontrollers.

The latest version has the power supply on the mainboard (it was on a separate board in the previous version).

Features are:

• JST connectors for UART1/2, I2C (TWI) and SPI
• all MCU pins are accessible through 0.1" pin sockets
• exchangeable external oscillator
• selectable supply voltage for MCU (3.3V, 5V, external)
• standard ISP (ICSP) and JTAG connectors
• replaceable UART-to-USB daughterboard
• versatile power sources: DC jack, USB and external
• beafy on-board power supply: 3.3V and 5V at 1A - enough to power peripheral devices like motors and lots of LEDs
• pull-up and pull-down resistors for I2C (TWI) and SPI can be enabled/disabled through jumpers
• ZIF (Zero Insertion Force) socket for MCU
