1. ESP-PICO-KIT Overview

1.1. ESP-PICO-KIT

ESP32-PICO-KIT is a mini development board based on the ESP32-PICO-D4 SIP module.

All the IO signals and system power on ESP32-PICO-D4 are led out through two rows of

20 pads populated with standard 0.1" pitch header pins. Developers can connect the

board to other circuit modules according to their needs. The development board integrates

a USB-UART Bridge circuit, allowing the developers to connect the development board to

a PC's USB port for downloads and debugging.

At the core of this development board is the ESP32-PICO-D4, a System-in-Package (SIP)

module with complete Wi-Fi and Bluetooth functionalities. ESP32-PICO-D4 integrates

several peripheral components seamlessly in one single package, that otherwise would

need to be installed separately. This includes a crystal oscillator, 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.

With its ultra-small size, robust performance and low-energy consumption, ESP32-PICO-

D4 is well suited for any space-limited or battery-operated applications, such as wearable

electronics, medical equipment, sensors and other IoT products.
