Single Servo Driver
Who
@Daniel Puratich
Where
What
Buck converter to power servo
CAN to PWM conversion for servo signal
smaller than the body of the servo so it can be sticky taped to it!
Why
See notes in schematic for some details
A nice summary: Architect project to remove long PWM cables used by the flight controller to talk to servos that are often far away on larger UAVs. This board removes the problems of PWM corruption and bus voltage sag by placing the PWM generator and low voltage power supply in close proximity to the servo while using a more robust protocol and higher voltage (lower current) power connection to span the distance between the flight controller and battery to the servo.
Relevant Programs
Intended for use on Fixed Wing 2025 as a required component. Removing it requires major architecture changes that would negatively impact the system.
Intended to controller servos for possible Big Quad 2025 water system. Water system POR is not decided. Not architecturally required as of October 2024, but could become so, especially if boards work.
