[Question] Possible to use bluetooth module with rev1 PCB? #118

Closed ghost closed 3 years ago

ghost commented 3 years ago

I have a few PCBs for the redox rev1 and I would like to add a bluetooth module to one of them. I would like to connect a Adafruit Feather 32u4 Bluefruit LE to the PCB which has hardware SPI capabilities.

From the breakout diagram of the Pro Micro, it looks like the SPI pins are on B1, B2, and B3. However, after looking at the QMK config.h file for the rev1, it looks like those pins are being used to define the keyboard matrix. From the QMK documentation, it seems that the Feather 32u4 Bluefruit LE is supported.

Is there a way to connect a bluetooth module to the rev1 PCB?

Hi,

If you really want a bluetooth version of the Redox I would suggest to use ZMK and a pair of nice!nano or bluemicro which should be compatible with the Redox rev1.

The pins you're looking are wired in such a way that doesn't allow for them to be used in other ways (i.e. they can only be used for matrix scanning and not SPI).

Understood. Thank you for the clarification and for the wonderful keyboard you've shared with us.
