Input device

i wanted to make 1 board that has general connectors to test the microcontroller and having access to the pins easily .. i started eagle and designed this board i call it: IO board which is input/output board ..

The design was made by eagle schematic

this board has the following features:

  • microcontroller Attiny44 with 20Mhz Xtal oscillator
  • LED indicator for power on
  • Servo connector (GND, Vcc, PA7)
  • connector 1 (GND, Vcc, Vcc, PB2, PA7, PA6)
  • connector 2 (PA5, PA4, PA3, PA2, PA1, PA0)
  • Connector 3 is FTDI interface
    • GND, NC, Vcc, PA0 TX, PA1 Rx
  • LED indicator for PB2 (good for blink)

The board can be used for general purpose Development…

an input device wasnt used in this week, i will have final project gyro sensor and will link it later to this week assignment.
