Summary

Compact snap-fit enclosure for the https://manuel-alvarez-alvarez.github.io/elrs-usb/ project — an ESP32-S3 firmware that turns any ExpressLRS receiver into a USB HID game controller for flight simulators.

Houses an ESP32-S3 Super Mini and an ELRS 2.4 GHz Mini receiver side by side in a pocket-sized form factor. Plug it into any PC via USB-C and fly with your radio transmitter — no drivers needed.

Design features

  • Two-piece snap-fit design (base + lid), no screws or hardware required

  • Honeycomb ventilation pattern on the lid for passive cooling

  • USB-C port cutout on one end for direct plug-in to your PC

  • Board retention rails sized for the ESP32-S3 Super Mini (22.5 x 18 mm)

What you need

  • 1x ESP32-S3 Super Mini dev board (or ESP32-S3 Zero from waveshare)

  • 1x ExpressLRS 2.4 GHz mini receiver (e.g. BetaFPV EP2, HappyModel EP1)

  • 4 wires soldered between the boards: 5V, GND, GPIO 12 → TX, GPIO 13 → RX

Print settings

  • 0.1 mm layer height

  • 0.2 mm nozzle

  • ABS or ASA recommended (better heat tolerance for enclosed electronics)

  • No supports needed
