ESP32S Wifi Bluetooth Combo Module

The ESP32S is a WiFi and Bluetooth combo module built around the Espressif ESP32 dual-core processor. It supports 802.11 b/g/n WiFi with speeds up to 150 Mbps and Bluetooth v4.2 (both Classic and BLE), making it a versatile foundation for IoT, wearable devices, and wireless projects.

With dual Xtensa LX6 cores running at up to 240 MHz, 520 KB SRAM, and a rich set of peripherals including capacitive touch, ADC, DAC, SPI, I2C, UART, and CAN, the ESP32S offers significant upgrades over the ESP8266 in a compact 16 × 24 mm module with a built-in PCB antenna.
