+
+Overview
+===========
+
+ESP32-PICO-DevKitM-2 is an ESP32-based development board produced by `Espressif <https://espressif.com>`_.
+
+The core of this board is `ESP32-PICO-MINI-02 <https://www.espressif.com/en/products/modules>`_ module with complete Wi-Fi and Bluetooth functionalities. The development board features a USB-to-UART Bridge circuit which allows developers to connect the board to a computer's USB port for flashing and debugging.
+
+All the IO signals and system power on ESP32-PICO-MINI-02 are led out to two rows of 18 x 0.1" header pads on both sides of the development board for easy access. For compatibility with Dupont wires, all header pads are populated with two rows of male pin headers. 
+
+.. note::
+
+    ESP32-PICO-DevKitM-2 comes with male headers by default.
+
+ESP32-PICO-DevKitM-2 provides the users with hardware for development of applications based on the ESP32, making it easier for users to explore ESP32 functionalities.
