CANbus IO Expander – Nano

(1 customer review)


New! V3 version, now available!

Available on back-order

SKU: PT-IONano Categories: , , Tags: ,



Emulates behavior of Haltech IO 12 box.

  • 4x 0v – 5v Analog inputs
  • 4x Digital Inputs (on – off state only)
  • 4x Digital pulsed outputs
  • Change from IO Box A or B by jumping pin A5 to ground or not.
There are limitations with this nano board:
– 200mA limit for the outputs.
– No frequency drive for the outputs. State or PWM only. (490hz or 980hz)
– 0v-5v on the AVI only, no input protection, no 12v input to AVI or DPI pins
-DPIs are state only (on or off), No Frequency measurements. Pull to ground.


Will come with an Arduino Nano with the code loaded on and tested.

Will come with 4 and 5 pin connectors and terminals.

Code for this project is on our gitHub –

    Brilliant. Used 4 of these now on both Haltech Elite and Link G4X and all worked flawlessly. Insane value.

    I also received excellent phone support from the developer when I messed up and accidentally reprogrammed the first one I tried. (I had near zero experience with Arduino)

    Go buy yourself a grab kit of Arduino header pins and connectors to make your wiring easy and solder free
