About

The ESP32 took over the maker world for a reason: two 240 MHz cores, Wi-Fi, Bluetooth (Classic and Low Energy), and a generous set of peripherals — capacitive touch pins, 12-bit ADC, DAC, SPI, I2C, I2S and PWM on almost every pin. This NodeMCU-style board brings all of it to a breadboard-friendly 38-pin package with a micro-USB port, EN/BOOT buttons and an on-board 3.3 V regulator. It is the board most ESP32 tutorials assume, so examples and libraries just work. Also available with the ESP-32E module or with a u.FL connector for an external antenna (ESP-32UE) — ask if you need those versions.
