FireBeetle 328P Low-Power Arduino Board (BLE 4.1)

The FireBeetle Board-328P with BLE4.1 is a low-power consumption microcontroller featuring an ATmega328P processor and a DIALOG BLE 4.1 chip. It operates at 3.3V (8MHz) and is compatible with Arduino Pro/Pro Mini. The board supports both BLE central and peripheral modes, multi-device cascade (up to 4 devices), and P2P wireless programming. Key low-power features include a 25µA standby current and dual interrupt wakeup capabilities. It has an onboard lithium battery charging circuit (400mA max) and can be powered by a 3.7V Li-ion battery or 3.7V-5.5V via VCC. Peripherals include 14 digital I/O, 6 analog inputs, SPI, I2C, and UART.

FireBeetle BLE 4.1 is compatible with the Bluno series (BLE 4.0) and performs much better. FireBeetle Board-328P with BLE4.1 is equipped with a more stable DIALOG Bluetooth 4.1 chip, supporting a maximum 4Kbyte/s transmission rate and low power consumption (25uA POWER DOWN). It can be directly applied to low power consumption application such as wearable and intelligent tools and so on.

It also supports bluetooth 4.1 multiple devices, KISS connections (approach connections) and is compatible with the Bluno series. Its connection can be realized by holding the host BOOT and moving to the target peripheral device.
