I am building a custom MacroPad that incorporates key switches, a rotary encoder, an I2C IO Expander, a Seeed Xiao ESP32-C3, and a mini-LCD screen that can display anything.

Finished most of the firmware and will need to program the display. Only the core BLE HID is there with all the keys and rotary encoder programmed. I also committed all the files to GitHub.

Revised schematic to include battery voltage sensing, pullup resistors for interrupts and I2C, and a decoupling capacitor for the I2C IO Expander to prevent brownouts. Also fixed PCB to reflect said changes.
