DFROBOT FireBeetle 2 ESP32-E IoT Microcontroller With Header
DFROBOT FireBeetle 2 ESP32-E IoT microcontroller with header. Features Wi-Fi, Bluetooth, USB-C, and low power for smart home projects.
The DFROBOT FireBeetle 2 ESP32-E is an IoT microcontroller equipped with headers, specially designed for Internet of Things applications. Based on the ESP-WROOM-32E dual-core chip, it supports Wi-Fi and Bluetooth dual-mode communication. Its compact size and low power consumption make it suitable for a wide variety of projects.
The board features an onboard charging circuit with a PH2.0 lithium battery interface and a USB-C power supply. It operates at 3.3V and includes a CH340K USB to UART bridge. With 4MB flash and 520KB SRAM, it provides ample memory for IoT applications. The GDI display port allows for straightforward screen connections, while 5 analogue pins and 10 digital pins offer versatile connectivity options alongside UART, I2C, and SPI interfaces.
Supporting Arduino programming, this microcontroller is also compatible with solder-free Gravity interface sensors and actuators, allowing users to get started effortlessly. The stamp hole design enables the board to be easily embedded directly into your PCB, saving both time and cost during prototype development. It also features a fool-proof design, an RGB-LED, and a 2mm mount hole.
The package includes the FireBeetle 2 ESP32-E board with headers, along with 18-pin and 14-pin male and female pitch pins for flexible setup.
