WE ARE NO LONGER SELLING THE PSC. However, HangTight.io is. Go here to see their version of the PSC. Their version does NOT have a UI, or the same feature set, but does support PWM and Analog, and is automatic detection with no setup needed.
If you need one urgently, feel free to email us, and we will put you in contact with them.
We do not, and will not support GPS, as it is unreliable and dangerous for on road vehicles or high speed motorsports.
