The RKAT40c Compact Project PCB for 40 pin Atmegas

This next board combines an Atmega chip which you have to supply and a easy to build minimal system board with parts.

The board is easy to assemble as it features only through hole parts and no smd parts

 

Features

  • Software is downloaded from a PC into the microcontroller from an Atmel AVR programmer or a FTDI USB cable
  • The clock reference can be either a ceramic resonator or crystal oscillator
  • All input and output pins are available via pin headers – you need to supply your own
  • Power supplied via either a DC socket or there is a 2 way header, the maximum input voltage is 5.5V DC max
  • Power can also be supplied from the FTDI cable connection, there is a 2 way header plug to select USB power
  • Power switch and LED power indicator

 

There are 2 methods of programming using this board

1) Software can be downloaded using a USB FTDI cable that connects from one of your PC USB port and to header J3.
2) Using an AVR programmer or equivalent, connect this to the ICSP 2×3 way header.

I soldered the resistors first, then the capacitors, switch, led, headers and then the socket

I have used an Atmega16 and an ATmega32 with this board
