It is a ZiiLab company in Korea.
A VTOL drone is being developed.
I am considering using the VOXL2.
1. 5G Network and Doodle Labs Helix modem
2. Minimum 12 PWM channels required

12 PWM channels are required, but only 8 are supported for VOXL FC. (4 rudder control, 5 motor control, 2 camera control, 1 spare, total 12 channel)
Is it possible to add a PWM channel?
Ex) VOXL 2 IO (4 channel)+ VOXL FC (8 channel)

Sorry for the delay. To achieve 12 PWM you would need a custom solution. You could likely use an Arduino Teensy or similar
