VOXL 2 Remote Controller Configurations
Table of contents
Summary
We are working to expand the capabilities of VOXL 2 every day. The built-in PX4 flight controller enables industry leading SWAP for an autonomous flight controller, but not every interface and flight controller are supported yet. This page provides an overview of available connectivity. If this connectivity is insufficient for your application, VOXL 2 is a world-class companion computer for autonomous navigation and AI when paired with an external flight controller.

Spektrum (DSMX)
Hardware
Tested hardware:
- Spektrum SPM9X45
NOTE: recomendded to have binding method outside of VOXL 2.
M0054 J19:
- Connector on board : SM12B-GHS-TB(LF)(SN)
- Mating connector : GHR-12V-S
Software
Checking Status
The px4-listener input_rc command can be used to check status.
PX4 Driver
See the ModalAI spektrum_rc driver.
CRSF
Hardware
PLEASE NOTE: the baud rates for the receivers likely need to be updated.
The baud rates for the receiver UART are set here when PX4 starts on VOXL2:
- MAVLink - https://github.com/modalai/px4-firmware/blob/voxl-dev-1.12/boards/modalai/rb5-flight/voxl-px4.config#L172
- CRSF - https://github.com/modalai/px4-firmware/blob/voxl-dev-1.12/boards/modalai/rb5-flight/voxl-px4.config#L175
Tested hardware:
- Happymodel ES900EX (in CRSF mode)
- TBS Crossfire Nano Rx (in MAVLink mode)
M0054 J19:
- Connector on board : SM12B-GHS-TB(LF)(SN)
- Mating connector : GHR-12V-S
Software
Checking Status
The px4-listener input_rc or px4-listener rc_channels command can be used to trouble shoot, if neither have been published it’s likely the receiver has yet to get RC data or the serial link isn’t working.
PX4 Driver
See the ModalAI tbs_crossfire driver.
The switch between MAVLink and raw CRSF are here and here.
