Concept
A smaller ESP32-family SoC with a single RISC-V core, ideal when you need Wi-Fi in a minimal footprint.
A little theory
RV32IMC core, 2.4 GHz Wi-Fi + BLE 5, 3.3 V GPIO. Fewer pins than S3/WROOM — plan wiring early. USB-Serial on SuperMini boards is common. In the classroom, treat ESP32-C3 SuperMini / DevKit as a intermediate part using Wi-Fi, BLE, GPIO, ADC, I2C, SPI, UART. Typical India street price is about ₹120–₹280. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
