Starting in VOXL SDK 1.1.1, VOXL 2 IO is being updated:
- new bootloader based on same bootloader as VOXL ESC (requires in field update, or request replacement by sending in existing hardware)
- new firmware based on same firmware as VOXL ESC
- for upgrade instructions, see the firmware guide
VOXL 2 IO is meant to be paired with VOXL 2 and adds PWM output along with S.BUS radio and Spektrum radio connections. It communicates over UART to VOXL 2 running PX4.
For documentation on the legacy PX4IO/VOXL SDK 1.1.0 and older usage, see here
