ESP32S Dev Kit C V4 NodeMCU WLAN Development Board compatible with Arduino (successor module of ESP32S Dev Kit C V2)

The AZ-Delivery ESP32S Dev Kit C V4 combines a CPU with 2 Tensilica LX6 cores, clocked at up to 240 MHz, and 512 kilobytes of SRAM in a single microcontroller. In addition, it integrates a radio unit for WLAN (according to 802.11b/g/n) and Bluetooth (Classic and LE). 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

With the new board layout, both the power supply and the reset circuit for automatic programming have been significantly improved.
