What is a SimpleDuino?

SimpleDuino is a single sided arduino compatible board. This board does not follow the standard Arduino pinout for shields and requires a serial connection either via FTDI, using an Arduino as an ISP or a direct serial connection via parallel.

Parts List:

MKI:

  • ATmega168 or ATmega328
  • 2x 22pF capacitors
  • 1x 16MHz crystal
  • 1x 5mm LED
  • 1x momentary button
  • 1x 10k resistor
  • 1x 220 ohm resistor
  • Your choice of male or female headers

MKII & III:

  • All parts from MKI list
  • L7805 or LM7805 voltage regulator
  • 2x 10uF capacitors

 

NB: J3 (comming from ATmega pin 1) requires a wire link soldered to J4 (under RST pin on the programming header). [only applicable for MKI & MKII boards]

 

Changelog:

MKII:

  • Added a voltage regulator to allow input from a range of power supplies between 7.5 and 25v. Header pins are still available for a regulated 5v input.

MKIII:

  • Reduced footprint to around 70 x 31mm (2¾ x 1¼").
  • Removed the programming header to save space, use the following pinout for programming:
  1. MOSI use D11
  2. MISO use D12
  3. SCK use D13
  4. RST use Reset (ATmega pin 1) 

     Components ID:

  • C1,C2 = 10uF
  • C3,C4 = 22pF
  • R1 = 10k
  • R2 = 220 ohm

Update: I have released a revision for each board solving an issue that causes the SimpleDuino to continually re-set (all good now).

 

It's my first go at Fritzing so please let me know if there are any errors.
