This ESP32S Dev Kit C was designed by AI-Thinker to provide an easy introduction to programming the new ESP32 dual core processor. With a host of new sensors and functions, this board represents the next step in IoT development. As with the predecessor model ESP8266, the WLAN functionality is implemented directly in the SoC, but with additional Bluetooth functionality (incl. BLE).

Compared to our alternative ESP32 Dev Kit version the ESP32 chip used here is a newer revision (Rev. 3). In addition, this board has the high-quality USB serial chip CH340 and even higher demands were made on the quality of the processing of the board.

Special features

  • The used ESP32 processor combines in a single microcontroller chip a CPU with 2 Tensilica LX6 cores, clocked with up to 240 MHz, and 512 kilobyte SRAM. In addition, it integrates a radio unit for WLAN (according to 802.11bgn) and Bluetooth (Classic and LE).
