ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution takes up the least amount of printed circuit board area. This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology, power and RF properties best, which is safe, reliable, and scalable to a variety of applications. Features: High performance-price ratio Small volume, easily embeded to other products Strong function with support LWIP protocol, Freertos Supporting three modes: AP, STA, and AP+STA Supporting Lua program, easily to develop Development Board: https://github.com/nodemcu/nodemcu-firmware/tree/dev-esp32 https://github.com/Nicholas3388/LuaNode If it cann't get bluetooth working? Using Node32s as the Board selection. To reference GPIO pins in code use just the number, for example "digitalWrite(13, HIGH)" sets GPIO13 high. The built-in LED to GPIO2. Package including: 1 x ESP32

ESP32 is a safe, reliable, and scalable to a variety of applications. SupportThree Modes: AP, STA, and AP+STA. Support LWIP protocol, Freertos. Ultra-Low power consumption, works perfectly. 2.4GHz Dual Mode WiFi + Bluetooth Development Board.
