The FireBeetle 2 ESP32-E, specially designed for IoT, is an ESP-WROOM-32E-based main controller board with dual-core chips.

Available with no headers attached or with female readers pre-soldered (select above). Both versions come with a pack of male and stacking headers too!

The board supports WiFi and Bluetooth dual-mode communication and features an onboard charging circuit with easy-to-use interface, which can be conveniently used for smart home IoT, industrial IoT applications, wearable devices and more. You can easily create your own IoT smart home system when connecting it with an IoT platform such as IFTTT.

FireBeetle 2 ESP32-E supports Arduino programming and will support Scratch graphical programming and MicroPython programming very soon. DFRobot provides detailed online tutorials and application cases, and there are thousands of sensors with solder-free Gravity interface and actuators to help you get started easily. The stamp hole design also makes it able to be easily embedded in your PCB, greatly saving your costs and time to build and test a prototype.

Note: FireBeetle 2 and FireBeetle pins and sizes are not compatible, and neither are the expansion boards.
