Bluetooth steering wheel shift paddles and button HUB (based on ESP32) [under testing]

Project Status

Steering wheel buttons and paddle shifters for racing simulators. Using cherry axis body, each side:

• 2 thumb buttons,
• 1 paddle shift button,
• 1 encoder,
• 4 buttons below

NOTE: Project is not complete

TODO:

• [x] 3.7 step down to 3.3V
• [x] AB with two encoders connected
• [x] Battery charging (TP4054/TP4057)
• [x]Key extension or SPI (74hc165)
• [x] Continue to connect
• [x] PCB split into two pieces
• [x] PCB proofing completed
• [x] 20210830: Recently, it was discovered that GPIO34~39 does not have an internal pull-up and needs to be connected to an external pull-up. The encoder connection is wrong. Currently, flying wires are used to solve the problem.
• [x] Under test, working normally
• [x] Improved the back cover of the model and added mounting holes on the model
• [x] Model 3D printing completed
• [x] 20211013: The schematic and PCB have been modified.
• [ ] The new version has not been proofed and tested, but it is theoretically OK. The PCB still needs to be beautified.
• [ ] 3D model completed and uploaded
