Beitian BN-880 GPS & Compass Module for iNav & Betaflight

Beitian BN-880 GPS & Compass Module for iNav & Betaflight


In Stock


The BN-880 is a well proven GPS module and is in fact the recommended GPS/Compass module for iNav. It's also a great addition to a quad if you are looking to take advantage of the new GPS Rescue mode in Betaflight. The module features a M8N GPS chip and HMC5883l I2C compass module, which together ensures a quick GPS 3D fix and a precise navigation capability.

The module has a flash memory for saving configuration, but for most applications including iNav and Betaflight it arrives ready for use - if using with iNav simply select a baud rate and Ublox for automatic configuration. When it comes to mounting the GPS, ensure the antenna is pointing up towards the sky and position it away from sources of interference such as your VTX antenna.
