FireBeetle Board-328P Microcontroller with Bluetooth 4.1, 3.7V
Low-power FireBeetle microcontroller with Bluetooth 4.1 for IoT. Features ATmega328P, Arduino IDE support, and lithium battery power.
The FireBeetle Board-328P with Bluetooth 4.1 is a low-power consumption microcontroller board designed for Internet of Things (IoT) development. It combines an ATmega328P Arduino-compatible controller with a stable DIALOG Bluetooth Low Energy (BLE) 4.1 chip, offering superior performance and significantly lower power draw compared to previous generations like the Bluno series.
This board is engineered for efficiency, featuring an ultra-low power consumption mode of just 25µA in POWER DOWN state, making it ideal for battery-powered and wearable applications. It supports a maximum data transmission rate of 4 Kbyte/s and includes advanced Bluetooth functionalities such as central/peripheral mode switching, serial data transmission, and peer-to-peer (P2P) wireless programming.
Key Features & Specifications
- Bluetooth 4.1: Features a more stable chipset supporting multiple device cascading (up to 4 devices), KISS proximity-based connection, and firmware updates over Bluetooth.
- Power Management: Supports USB charging and direct power from a 3.7V lithium battery, perfect for portable projects.
- Dual Wake-up System: Implements a double-interrupt wake-up mechanism where the BLE module can wake the ATmega328P via pin D2 (high level), and the microcontroller can wake the BLE module via pin D3 (low level).
- Rich I/O: Provides extensive connectivity with 14 digital I/O pins, 6 analogue input pins, and dedicated SPI, I2C, and UART interfaces for connecting a wide array of sensors and peripherals.
- Programmability: Fully supported by the Arduino IDE for easy development and comes with an Arduino Bluetooth library.
- Status Indication: Equipped with LEDs for clear visual feedback on board and Bluetooth status.
The board is supplied as a complete kit, ready for prototyping and integration into your next smart device or IoT solution.
