Freeplay CM3 L2R2 ADC Add-On Board (PRESALE)


The photos shown are only meant as usage examples. The product delivered may be different. Please read below.

This add-on board’s main feature is to add analog inputs and L2/R2 “trigger/shoulder” buttons. This kit will require adding parts to your existing Freeplay CM3 which may involve soldering or shell modifications. You can choose 2 or 4 analog inputs, and you can choose to purchase it with or without a fan.

This add-on board adds 3 new buttons (likely mapped as L2, R2, and hotkey). It also adds 2 (or optionally 4) analog chips (via i2c) that can be used by the Freeplay joystick driver for something such as a PSP1000 analog stick. 2 analog inputs is enough for a single analog stick, but you can choose to have all 4 analog chips installed if you want to experiment with adding other features. Note that the green and red wire pair shown in the photos are coming from a PSP1000 analog stick we have installed for testing.



This is a pre-sale item. We are developing this add-on board and the documentation that should go with it. We’ve had some interest already, so we have decided to see how many people are actually interested enough to be early adopters. This is mainly for those people that want to order one to test it out and see how it works.

This product is for advanced users that are comfortable soldering and tinkering with the Linux code/scripts. Please ask us if you have any questions about this.

The photos/videos shown here are from a test unit. The green wire that runs from “45-SCL” is completely unnecessary. The white wire that runs from “40” is only necessary if you want to program the Pi to turn the fan on/off when necessary. You could also wire it full on or add a switch (on your own) if you want to go that route.
