Espressif ESP32-PICO-KIT V4 USB-UART ESP32 SiP Development Board

Overview ESP32 PICO KIT is a mini development board produced by Espressif At the core of this board is the ESP32 PICO D4 a System in Package SiP module with complete Wi Fi and bluetooth functionalities Comparing to other ESP32 modules the ESP32 PICO D4 integrates several peripheral components in one single package that otherwise would need to be installed separately This includes a 40 MHz crystal oscillator a 4 MB flash filter capacitors and RF matching links in This greatly reduces quantity and costs of additional components subsequent assembly and testing cost as well as overall product complexity The development board integrates a USB UART Bridge circuit allowing the developers to connect the board to a PCs USB port for downloads and debugging For easy interfacing all the IO signals and system power on ESP32 PICO D4 are led out through two rows of 20 x 0 1 pitch header pads on both sides of the development board To make the ESP32 PICO KIT easier for Dupont wires 2 x 17 header pads are populated with two rows of female pin headers The remaining 2 x 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 Functional Description The following list and figure below describe key components interfaces and controls of ESP32 PICO KIT board ESP32 PICO D4Standard ESP32 PICO D4 module soldered to the ESP32 PICO KIT board The complete system of the ESP32 chip has been integrated in
