N-O LILYGO ESP32 ESP32S Development Board 2.4GHz Dual Mode WiFi Plus Bluetooth Ultra Low Power Dual Cores Microcontroller Processor Integrated with ESP32s Antenna RF AMP Filter AP STA for IDE

ESP32 has integrated antenna and RF balun, power amplifier, low noise amplifier, filter and power management module. The entire solution occupies the smallest printed circuit board area. The board uses TSMC 40nm low-power technology with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips, with the best power and RF performance, which is safe, reliable and scalable to various applications. Features: Cost-effective Small size, easy to embed other products Powerful functions, support LWIP protocol, Freertos Support three modes: AP, STA and AP + STA Support Lua program, easy to develop Development board: https: //github.com/espressif/-esp32 https://github.com/nodemcu/nodemcu-firmware/tree/dev-esp32 https://github.com/ Nicholas3388 / LuaNode If it cann't get bluetooth working? Use Node32 as the board choice. To reference GPIO pins in the code, use only numbers, for example, "digitalWrite(13, HIGH)" sets GPIO13 to high. Built-in LED of GPIO2. The package includes: 1 * ESP32 development boards
