Hardware Reference

Introduction​

This page provides details for hardware developers for future boards to ensure maximum compatibility with Betaflight.

Target Maintenance​

The manufacturer is responsible for supporting their hardware: its config and documentation, faults, warranty and customer support, and keeping its target working as Betaflight moves forward. Target files are being separated as much as possible to the main code so as to facilitate this. The Betaflight team fixes bugs in the firmware, the Betaflight App and the cloud build, and does not provide end-user hardware support. See the Hardware Policy.

Adding new targets​

If you are adding a new flight controller then:

  1. Make any PRs against the master.
  2. Don't change the travis.yml or fake_travis_build.sh files - these are just for a subset off all builds to check PRs
  3. Add page to board section in support describing the flight controller and giving a link to at least one supplier.
