Uno32 board (schematics, manual, Eagle files) is compatible with Arduino platform, but based on Microchip PIC32MX320 microcontroller.

Features:

  • PIC32MX320 microcontroller 80 MHz (MIPS architecture)
  • 43 usable i/o pins
  • Compatible with Arduino shields
  • MiniUSB connector with FTDI convertor to UART1
  • Power select switch: from USB or from external source
  • External power connector
  • One power LED and two user LEDs
  • Reset button

Memory:

  • 128 kbytes of Flash memory
  • 12 kbytes of additional boot Flash memory
  • 32 kbytes of RAM

Digital outputs can sink or source up to 18 mA. A rich set of peripheral functions is available: UART, SPI, I2C, ADC, timers. Two internal oscillators available: 8 MHz and 32 kHz. Power can be sourced from miniUSB, or from external power supply +7 ... 15 VDC.
