The UBW32 communicates with the computer via USB. The board can received power via USB or through an external power supply.


Hardware Features:

  • Uses PIC32MX460F512L microcontroller
  • 78 usable I/O pins - all header holes on .100" grid (73 for easy "DIP" style breadboard mounting
  • miniUSB connection - supplies power and full speed USB connection to PC
  • 3.3V power regulator
  • 5V power regulator allows higher voltage (battery or other) power input
  • Power Select switch allows selecting between USB and external power (acts as power-on switch)
  • Ground, 3.3V and 5V pins available on both sides for vertical breadboard mounting
  • 5 LEDS - 1 for power, 4 under software use
  • 3 push buttons - 1 for reset, 2 for software use
  • Header and footprint for USB Host connector - with the right software, allows for USB Host functionality
  • Minimal board size - very thin (.28" high, 4.4" long, 1" wide) and 2 mounting holes
  • Input protection fuse allows 500mA from the power supply
  • Pads on underside of board for 5V pull up resistors on all non-analog I/O pins
  • External input power protected by diode

The UBW32 comes loaded with a Bootloader and Firmware.
