FireBeetle 2 ESP32-E IoT Microcontroller, With Header - 

DFR0654-F is a FireBeetle 2 ESP32-E IoT microcontroller with header (supports Wi-Fi & Bluetooth). FireBeetle 2 ESP32-E, specially designed for IoT, is an ESP-WROOM-32E-based main controller board with dual-core chips. DFR0654-F supports Wi-Fi and Bluetooth dual-mode communication and features a small size, ultra-low power consumption, onboard charging circuit, and easy-to-use interface, which can be conveniently used for smart home IoT, industrial IoT applications, wearable devices, and so on. You can easily create your own IoT smart home system when connecting it with an IoT platform like IFTTT. FireBeetle 2 ESP32-E supports Arduino programming and will support Scratch graphical programming and MicroPython programming very soon. There are thousands of sensors with welding-free Gravity interfaces and actuators to help you get started easily. Besides, the stamp hole design makes it able to be easily embedded in your PCB, greatly saving costs and time to build and test a prototype.
