The AZ-Delivery 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.

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

  • As with the predecessor model ESP8266, the WLAN functionality is implemented directly in the SoC, but with additional Bluetooth function (incl. BLE).
  • Support for simultaneous charging and transfer of data. The ESP32 processor used combines a CPU with 2 Tensilica LX6 cores, clocked at up to 240 MHz, and 512 kilobytes of SRAM in a single microcontroller chip.n
  • It also integrates a radio unit for WLAN (according to 802.11bgn) and Bluetooth (Classic and LE).
