The current OSBee shield would not work for RPi — because it requires one PWM pin with fairly high frequency to generate the boosted voltage. I don’t know if RPi support PWM or not, and if so, what’s the frequency.
A better design for OSBee shield would be to have a dedicated boost converter, like how OpenSprinkler DC circuit is designed. Unfortunately we are not in the cycle to re-design OSBee shield yet.
The standalone OSBee is temporarily put on hold, partly because 24V AC valves are still more common (than latching valves) on the market.
