Frequently Asked Questions

What is the input voltage for the BotLink ExpressLRS Receiver V1?

The receiver is powered via its UART interface and requires a standard 5V supply, which is typically provided directly from the flight controller's 5V BEC or UART power rail. Ensure your flight controller can deliver clean 5V power to ensure stable receiver operation.

How do I update the firmware on this receiver?

The receiver supports both DFU (Device Firmware Upgrade) and UART boot modes for firmware updates. You can use the ExpressLRS Configurator tool to flash the latest firmware via a USB-to-serial adapter connected to the receiver's UART pins. Always ensure you have a backup of your configuration before updating.

What antenna is included and is it suitable for long-range flying?

The package includes a 2.4GHz dipole T-antenna, which provides good omnidirectional reception for most FPV and RC applications. For extreme long-range flights, a high-gain directional antenna on the transmitter side is recommended, but the included antenna is sufficient for typical long-range freestyle and racing scenarios.

Is this receiver compatible with all ExpressLRS transmitters?

Yes, the BotLink Receiver V1 runs the open-source ExpressLRS firmware and is fully compatible with any ExpressLRS transmitter (e.g., RadioMaster, HappyModel, Jumper) running the same major firmware version. Ensure both transmitter module and receiver firmware versions are matched for optimal performance.
