If you'd like to build your own CTR2-Dial then I've made the components available here for purchase.
The encoder and 3.5mm jack interfaces include voltage divider circuits to reduce the 5V input voltage supplied by the M5Dial down to 3.3 volts for use on the M5Dial’s input pins.
Each interface is supplied with a wiring harness that simply plugs into the M5Dial’s I/O port (the jack interace should be plugged into port B).
A high quality print of the case (with feet and screws) is also available here. Alternatively you can download the STL files for the various styles on Printables. You will need six non-slip feet for the base as well as 4 M3x6-8mm screws to attach the base to the shell.
I can include the battery harness and cable but not the battery with the kit as I'm unable to ship these stand-alone. The one I provide is a 2000mAh EEMB LiPo but any other brand/size can be used if they fit inside the case.
You will require a licence for the CTR2-Dial firmware. This can be obtained from Lynn here.
