Demiduino, another tiny Arduino compatible board

Tuesday, February 7th, 2012

Wade made a tiny Arduino compatible board. It has 8 Digital I/O pins, 4 Analog pins, and an on-board lipo charger.  The ATmega32U4 microcontroller has more memory than the original Arduino. Digital pins 0-7, Analog 2-5, and a RST, V+, and GND pin are broken out to two rows of...

  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
