30-Pin ESP32 Expansion Board with USB Type-C and Micro USB Dual Interface

The 30-Pin ESP32 Expansion Board with USB Type-C and Micro USB Dual Interface variant uses a shorter pin-count layout than the 38-pin version — same dual-core ESP32 processor, same WiFi and Bluetooth capability, but with a narrower PCB footprint that fits tighter chassis and enclosure builds. The ESP32 Expansion Board 30-pin provides a dedicated base for that module, breaking all 30 GPIO connections out to accessible headers while adding power regulation and dual USB interface on the same board.

That combination removes the need for a separate USB-to-serial programmer or an external power regulator when moving from bench to field deployment. The esp32 expansion board power input accepts either 6.5V to 16V DC through a barrel connector or standard 5V through USB — both the Type-C and Micro USB ports work for programming and power simultaneously. That wide DC input range covers 9V wall adapters, 12V automotive power, and 2S LiPo battery packs directly without a step-down converter between the supply and board.

The dual-core processor count of 2 confirms this 30-Pin ESP32 expansion board works with the standard dual-core ESP32 module — one core handles the wireless stack while the second runs application firmware. Expanding the pin count to an accessible breakout format while adding versatile power options is what separates this board from plugging the ESP32 module directly into a breadboard. The expansion board 30-pin suits sensor network hubs, gateway device prototypes, and builds compact IoT controller. Available on StemVolt. This board is developing ESP32-based projects and practical GPIO expansion.
