AtMega 8535/16/32/324/644/1284 generic board

Briefly about the features of the scheme:

  • Nearly all GPIO pins connected to PLS terminals.
  • Two GPIOs are connected: button (SW1 / PC5) and the LED (LED1 / PC4).
  • External pull-up on UART RX0 / RX1.
  • R-dividers for 3.3V-TTL on UART TX0 / TX1.
  • SPI pins for 3 devices connected to (for example): Ethernet (Wiz5500 / ENC28J60), Sd-Card, CAN MCP2515 and so on ...
  • Compatible with Arduino Sanguino/Mightycore
