About the FM-Radio-Using-ESP-12E-and-RDA5807M PCB

FM-Radio-Using-ESP-12E-and-RDA5807M is an open source ESP8266 PCB design by ItzzInfinity, published on GitHub under the MIT license. It is a 2-layer board measuring 47.5 × 28.3 mm, with 9 components from 6 distinct parts.

Its main chip is the ESP-12E, from the ESP8266 family. Other key parts include the RDA5807M. By type, the board carries 4 capacitors and 1 IC.

It belongs with the power & battery, audio and rf & radio designs in this gallery.

From the project

An FM radio receiver built using an ESP12E, interfaced with the RDA5807M module. Powered by a Li-Ion battery with a TP4056 charging module, amplified by a PAM8403, and output through a 10-watt speaker. Features station switching via a button.

A small FM receiver built around the RDA5807M, driven over I2C by either an ESP32-C3 SuperMini or an ESP-12E — the carrier board has a footprint for both and the firmware picks its pin map from whichever core you compile for.

Audio leaves the board on a 2-pin header to a PAM8403 amplifier and a speaker; a telescopic antenna solders to a plated mounting hole. Beyond the original button-cycles-presets behaviour, the current firmware brings up Wi-Fi and serves a web UI at http://radio.local for presets, volume, seek and manual tuning, supports OTA reflashing, and optionally drives an…
