FireBeetle 2 ESP32-E (N16R2) IoT Microcontroller
The FireBeetle 2 ESP32-E (N16R2) IoT development board is equipped with 16M Flash, 2M PSRAM, and a 32-bit dual-core processor clocked at 240MHz. Built on Espressif's ESP32-WROOM-32E-N16R2 module, it supports dual-mode Wi-Fi and Bluetooth communication, making it ideal for IoT applications. The board features multiple peripheral interfaces, including 17 digital pins, 11 analog pins, UART, SPI, I2C, I2S, and DAC interfaces, catering to various hardware needs.
With support for dual power supply modes (USB and 3.7V lithium battery) and automatic switching, it ensures power efficiency. It also supports programming via Arduino IDE, ESP-IDF, and Micro-Python, offering flexibility for developers. Measuring just 25.4mm x 60mm, the compact design is suitable for embedded projects. The onboard PCB antenna offers space-saving benefits, while an external antenna (with the ESP32-WROOM-32UE variant) can provide greater signal range.
This low-power development board is perfect for IoT projects requiring efficient performance and compact design.
