ALMOCN 2PCS ESP WROOM 32 ESP32 ESP 32S Development Board 2 4 GHz Dual Mode WiFi Bluetooth Dual Cores Microcontroller Processor Integrated Compatible with Arduino IDE

Reference links of ESP32: github.com/espressif/arduino-esp32 github.com/nodemcu/nodemcu-firmware/tree/dev-esp32 Features: 1.The ESP32 integrated with Antenna switches, RF Balun, power amplifiers, low-noise amplifiers, filters, and management modules, and the entire solution occupies the least area of PCB.  2.2.4 GHz Wi-Fi plus Bluetooth dual-mode chip, with TSMC Ultra-low power consumption 40nm technology, power dissipation performance and RF performance is the best, safe and reliable, easy to extend to a variety of applications. 3.Small volume, easily embeded to other products 4.Strong function with support LWIP protocol, Freertos 5.Supporting three modes: AP, STA, and AP+STA 6.Supporting Lua program, easily to develop 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: 2 x ESP32 Development Board
