The ESP32 is a high-performance, low-power Wi-Fi and Bluetooth dual-mode system-on-chip with 40nm process for ultra-high RF performance, stability and reliability. Built-in Xtensa LX6 dual-core 32-bit processor with up to 240MHz, 520KB of SRAM and 448KB of ROM, and support for external memory expansion, the ESP32 also integrates a rich set of peripheral interfaces. ESP32 also integrates rich peripheral interfaces. In addition, it supports multiple communication protocols, has strong security encryption function, and can be developed through various programming environments, such as MicroPython, which is widely used in IoT and smart home applications.
MCU : ESP32 is a dual-core MCU with integrated Wi-Fi and Bluetooth, featuring low power consumption, high performance, rich peripheral interfaces and support for multiple communication protocols, which is suitable for IoT, smart home and other application scenarios.
2.0 Battery Interface: 480Mbps transmission rate, supports USB 2.0 standard, provides stable power transmission and data connection for devices.
USB:CH340X: Supports the highest baud rate up to 2Mbps and has a built-in transceiver buffer to ensure data transmission stability. The built-in clock eliminates the need for an external crystal, simplifying circuit design and providing reliable and stable data transmission.
Switch on/off reset key: under power condition, short press once to turn on the power and reset, short press twice to turn off the power.
The main chip adopts a low-power dual-core 32-bit CPU with a main frequency of up to 240MHz.

1 x Development Board
1, the module is connected to the PCB on-board antenna by default (i.e. only connect the 0OR resistor at ①);
2、If you need to use // mount external antenna, just connect the 0OR resistor at ② (you need to replace the 0R resistor position by yourself);
3、The 0R resistor can only be placed at ① or ②, corresponding to the use of different antennas, can not be placed at the same time!
