At the core of this board is ESP32 chip, which is a single 2.4GHz WiFi and Bluetooth

combo chip designed with TSMC’s 40 nm ultra-low power technology. ESP32-PICO-D4

integrates all peripheral components seamlessly, including a crystal oscillator, flash,

filter capacitors and RF matching links in one single package. Given that on other

peripheral components are involved, module welding and testing is not required either.

For easy interfacing, all the IO signals and system power ESP32-PICO-D4 are led out

through two rows of 20×0.1” pitch header pads on both sides of the development board.

To make the ESP32-PICO-KIT easier for Dupont wires, 2 ×3 header pads grouped on

each side of the board besides the antenna are not populated and may be populated

later by the user if required. As such, ESP32-PICO-D4 reduces the complexity of the

supply chain and improves control efficiency.
