A bidirectional logic shifting board for converting 3.3V logic down to 2.5V or 1.8V. There is also a VOUT terminal which can source power at the selected voltage.


Useful for users who have external boards that run on lower logic thresholds, or simply want a 3.3V, 2.5V, or 1.8V supply. The logic terminals presented on this accessory board are for communication purposes only, they cannot drive relays or other forms of load.

  • Supports bi-directional communication
  • Up to 800kHz
  • 3.3V, 2.5V, or 1.8V
  • VOUT terminal can source up to 200mA

Note: Advanced users may convert the 1.8V option to 5V by installing a jumper on R5, and removing or destroying the voltage regulator marked U3.
