Important Update

Starting in VOXL SDK 1.1.1, the VOXL 2 IO system is being updated, with changes including:

• a new bootloader based on same bootloader as VOXL ESC
• a new firmware based on same firmware as VOXL ESC
• a new voxl-px4 driver voxl2-io to support new firmware

Existing VOXL 2 IO may be updated but requires a bootloader update over the debug header. This can be done in the field, or contact ModalAI to arrange a swap out if needed.

For updating the legacy firmware, please see the firmware guide.

Features

Spektrum receivers connect directly to VOXL 2 (spektrum_rc driver) on current firmware, not through VOXL 2 IO. The legacy PX4IO firmware supported Spektrum input; see the legacy user guide.
