EMWaver Shield

EMWaver Shield

EMWaver Shield is a shield-style carrier for an ESP32‑S3 module. It adds the same IR receiver + IR LED and USB feature set as the DIY approach, but in a different form factor. For the sub‑GHz radio, it’s designed for soldering an RFM69HW module with a helical antenna, enabling up to 20 dBm output power. It also breaks out a larger duplicated GPIO header (22 pins) to make prototyping and expansion boards easy. Bonus: the ESP32‑S3 native USB stack also enables USB device emulation.
