USB-OTG ESP32 with AI/vector instructions — modern IoT classroom board.
Interface: Wi-Fi, BLE, USB-OTG, GPIO, ADC, I2C, SPI
ESP32 can run similar Wi-Fi lab patterns; pin numbers differ from NodeMCU silk.

Concept
ESP32-S3 improves on classic ESP32 with native USB and richer GPIO for sensors and tinyML demos.
A little theory
Dual Xtensa LX7, Wi-Fi + BLE 5, USB Serial/JTAG built-in on many DevKits (no external CH340). Still 3.3 V I/O. Strapping pins remain critical at boot. In the classroom, treat ESP32-S3 DevKit as a intermediate part using Wi-Fi, BLE, USB-OTG, GPIO, ADC, I2C, SPI. Typical India street price is about ₹280–₹550. 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.
How it works in a project
Arduino-ESP32 board package → select ESP32S3 Dev Module. Use USB for serial + sketch upload.
