SpeedyBee BT Nano 3 Wireless FC Configurator

The SpeedyBee BT Nano 3 is a micro-sized Bluetooth 5.0 module designed to add wireless configuration to flight controllers lacking integrated Bluetooth or Wi-Fi. By soldering this module directly to an available UART, builders can tune PIDs, change motor directions, adjust rates, and configure GPS directly from a smartphone via the SpeedyBee app, eliminating the need to haul a laptop to the field.

Key features

• Bluetooth 5.0 LE provides a fast, stable connection to the SpeedyBee iOS and Android apps.
• Direct UART integration leaves USB ports free and works securely inside sealed or hard-to-reach builds.
• Full wireless configuration support for flight controllers running Betaflight, INAV, or Emuflight.
• Bare-board nano form factor adds minimal weight and fits effortlessly inside micro frames and dense stacks.
• Bluetooth switches off automatically while the drone is armed so it cannot interfere with other radios in flight; a BT switch pad can also disable it on a low signal.

Specifications

• Wireless protocol: Bluetooth 5.0 LE (Wi-Fi used only for the module's own firmware updates)
• Input voltage: 5V DC
• Working current: max approx. 87 mA at 5 V
• Required connection: 1x UART (5V, GND, TX, RX)
• Baud rate: 115200
• Supported firmware: Betaflight, INAV, Emuflight
• Size: 14 x 11 x 0.8 mm
• Weight: 5 g

To set up the module, wire it to an open flight controller UART ensuring the RX and TX pads cross over (module RX to FC TX, and module TX to FC RX). In your firmware's Ports tab, enable MSP on the corresponding UART and set the baud rate to 115200 to establish communication with the app.
