SoC Espressif ESP32 Series

ESP32 Series

32-bit MCU & 2.4 GHz Wi-Fi & Bluetooth/Bluetooth LE

  • Two or one CPU core(s) with adjustable clock frequency, ranging from 80 MHz to 240 MHz
  • +19.5 dBm output power ensures a good physical range
  • Classic Bluetooth for legacy connections, also supporting L2CAP, SDP, GAP, SMP, AVDTP, AVCTP, A2DP (SNK) and AVRCP (CT)
  • Support for Bluetooth Low Energy (Bluetooth LE) profiles including L2CAP, GAP, GATT, SMP, and GATT-based profiles like BluFi, SPP-like, etc
  • Bluetooth Low Energy (Bluetooth LE) connects to smart phones, broadcasting low-energy beacons for easy detection
  • Sleep current is less than 5 μA, making it suitable for battery-powered and wearable-electronics applications
  • Peripherals include capacitive touch sensors, Hall sensor, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C
