ESP-SDR uses the undocumented raw I/Q capture functionality of ESP32 family chips to turn them into (low-duty-cycle) Software Defined Radios

Turn Amazon Echos (Echo Dot 3, Echo Dot 2, Echo 2) into local Home Assistant voice satellites. Keeps Amazon's mic processing and wake word engine, replaces Alexa with a small C daemon speaking ESPHome or Wyoming. Multiroom music via Music Assistant, Bluetooth speaker and proxy, no cloud.

Ultra-minimal, zero-CPU 5.8 GHz analog FPV video receiver using ESP32-C5 Wi-Fi 6 PHY MODEM_DIAG, BitScrambler WBFM demodulation & resistor DAC CVBS

C99 firmware core for a 16-series LFP pack. Independent charge and discharge FETs, cell protection, coulomb SOC, and the current and voltage limits an inverter follows. Passive balance runs for 1.0 s, then 200 ms off, so the fault wait finishes on an unloaded sample. No RTOS, no heap. The AFE driver and fieldbus stay on your board.

Whistle speech-to-text running fully on an ESP32-S3: hold a button, say a colour in one of 7 languages, the LED does it. No network.
