New Board--PICO1TRC, 2.1"x1.65", TH, Adj Reg, RTC

Yesterday at the MIT Flea I introduced a new board -- the PICO1TRC.
The PICO1TRC is a TH kit with a 2.1" x 1,65" PCB. The kit features an
ATmega328 with the Arduino bootloader. This board has an adjustable
voltage regulator, battery backed-up real-time clock and a
0.6" x 0.6" prototyping area. The kit is priced at $20.
The datasheet contains the schematic, BOM and
assembly instructions. See Loading...


  • 2.1" x 1.65"
  • TH components,
  • Replaceable ATmega/328
  • Real-time clock with battery backup
  • 2.1mm power jack and an adjustable regulator.
    The Vcc can be trimmed from 3.3V to 5V by changing a single
    resistor. There are resistors in the kit to trim Vcc to 3.3V and 5V.
  • 0.6" x 0.6" prototyping area
  • Six pin header compatible with the FTDI TTL-232R-3V3 cable.
  • Debug LED
