Description:
FireBeetle 2 ESP32-E, specially designed for
IoT, is an ESP-WROOM-32E-based main controller board with dual-core chips.
It supports WiFi and Bluetooth dual-mode communication and features a small size, ultra-low power consumption, on-board charging circuit, and easy-to-use interface, which can be conveniently used for smart home IoT, industrial IoT applications, and 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.
Note: FireBeetle 2 and FireBeetle pins and sizes are not compatible, and neither are the expansion boards.
