Description :

-ESP32-PICO-KIT is a mini IoT development board with functionalities of WiFi and Bluetooth
-It has a compact size of 52x 20.3x10mm and integrates a 4 MB SPI flash and a USB-UART Bridge circuit
-The board is well suited for space-limited or battery-operated applications such as wearable electronics and medical equipment
-At the core of the board is ESP32 chip, a single 2.4GHz WiFi and Bluetooth combo chip
-ESP32-PICO-D4 integrates all peripheral components in one single package, reducing complexity and improving control efficiency
-The board has 20×0.1″ pitch header pads on both sides for easy interfacing
-It also has 2×3 header pads grouped on each side of the board that can be populated later by the user if required.
