| FireBeetle ESP32 IOT Microcontroller Supports & Bluetooth SKU DFR0478 Introduction DFRobot FireBeetle series is the low-power consumption micro-controller intentionally designed for Internet of Things IoT projects. FireBeetle Board - ESP32 integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Bluetooth dual-mode communication. The electric current is just 10uA in the deep-sleep mode. The main controller supports two power supply methods USB and 3.7V external lithium battery. And both USB and external DC can charge the Lipo battery directly.<br4> FireBeetle Board-ESP32 has made a special hardware design for Arduino IDE. You can make a download without switching booth-mode manually. It supports Arduino, IDF linux , micropython etc. Moreover, FireBeetle made a pin mapping for Arduino IDE. It can be configured with Dx transport, compatible with UNO and reduce the entry barrier. The small size and high performance makes FireBeetle become idea solution for IOT low power consumption projects. Please kindly note that developers are the most common users of FireBeetle Board-ESP32 and not all of the peripherals have examples for reference, and there are still some bugs being found and fixed. For Arduino IDE, all GPIO function, I2C/SPI communication has been working. But the other functions are still under development. We recommend this board for experienced engineer. • Compatible with products in the DFRobot FireBeetle serials • Low-power consumption the electricity current under ultra-low power is 10uA • Quick Response the top frequency is 400KHz • Cost-effective • Small size, convenient to install Specification • Working voltage 3.3V • Input voltage 3.3V~5V • Support electric current of low power consumption 10 uA • Support maximum discharge current 600mA • Support maximum charge current 500mA • Support USB charging. • Processer Tensilica LX6 dual core processer One for high speed connection one for independent programing . • Frequency 240MHz • • • Wi-Fi • Wi-Fi protocol b/g/n/d/e/I/k/r 802.11n, high speed can reach to 150 Mbps , converge A- MPDU and A-MSDU, supporting 0.4us protecting interval. • Frequency range GHz • Bluetooth protocol Comply with BR/EDR/BLE standard of Bluetooth v4.2. • Bluetooth audio the current under low power consumption of CVSD and SBC is 10uA • Working current 80mA in average • Frequency range 2.4~2.5GHz • Support one-key downloading. • Support micropython. • On-chip clock 40MHz crystal and KHz crystal. • Digital I/O 10 default setting of arduino • Simulative input 5 default setting of arduino • SPI 1 default setting of arduino • I2C 1 default setting of arduino • I2S 1 default setting of arduino • • Interface FireBeetle series compatible • Working temperature -40 ~+85 • Dimension 24 x 53 mm /0.94 x 2.09 inches • The dimension of mounting hole inner diameter 3.1mm outside diameter 6mm. Board Overview FireBeetle Board - ESP32 is not only compatible with ESP32 PinMap, but also make a special compatible with Arduino IDE PinMap.
