Description :

– FireBeetle 2 ESP32-E is a low-power consumption microcontroller board designed for IoT projects
– It is based on the ESP-WROOM-32E module and supports WiFi and Bluetooth dual-mode communication
– It has a small size, ultra-low power consumption, onboard charging circuit, and easy-to-use interface
– It can be used for smart home IoT, industrial IoT applications, wearable devices, and more
– It supports Arduino programming and will soon support Scratch graphical programming and MicroPython programming
– Detailed online tutorials and application cases are provided, and there are thousands of sensors and actuators available to help you get started
– Two versions are available: unsoldered and pre-soldered with headers
– Note: FireBeetle 2 and FireBeetle pins and sizes are not compatible, and neither are the expansion boards
– Espressif has released an ECO V3 version of the ESP32 chip with bug fixes and improvements, including a fix for a PSRAM cache bug, a fix for read errors when accessing certain address spaces simultaneously, improved stability of the 32.768 KHz crystal oscillator, and the ability to support a lower baud rate for the CAN module.
