Hardware Overview

A 2×3 of Waveshare ScreenKey modules (128×128 LCD + switch each) on an ESP32-S3 carrier, in a printed case. You fabricate the board, print the shells, and screw the modules on — sources are in hardware/.

Rev E is the current layout: dual SPI to the panels, IMU, ambient light, haptics, eight edge-glow LEDs, and a Qwiic port.

Order a PCB

  1. Generate fab outputs: ./scripts/build_hardware.sh
  2. Upload hardware/pcb/data_streamdeck_gerbers.zip to JLCPCB (~$15 for five boards)
  3. SMT assembly is recommended on Rev E — IMU, ALS, haptic driver, and eight 3535 LEDs are fiddly by hand. Component list in hardware/pcb/bom.csv

See the Fab Checklist for pre-order verification and bring-up tests.
