Introduction
DFRobot FireBeetle series are low power consumption microcontrollers designed for Internet of Things (IoT) development. This Bluetooth controller combines Bluetooth Low Energy 4.1 with Arduino controller, offering functions similar to the former Bluno series but with lower power consumption. You may also check the Bluetooth microcontroller selection guide to get more information.
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.
