Audio
Audio is an open source PCB design by anton-vinogradov: a 2-layer, 80 × 60 mm board with 19 components (12 distinct parts). Filed under audio and rf & radio.
Open multiband RF handheld on ESP32-S3 + ESP32-C5 — successor to esp32-leshy / ESP32-DIV
2.4/5-GHz Wi‑Fi · BLE · 802.15.4 · 3× nRF24 · Sub‑GHz · VHF/UHF · FM/AM/SW/LW/Airband · IR · LoRa/CC1101+NFC Cap

Leshy2 is intended to be a hobby device combining spectrum observation, communication, diagnostics and safe experimentation without a mandatory laptop. The first order targets one genuinely working prototype: the factory supplies two populated PCBAs and the owner completes a simple, solder-free final assembly.
