Hi folks! I bought this Delta Electronics D12S300-1 board recently, which is similar to the 300W GE Raptor chip. The pinout is basically the same as the Raptor and OKR for that matter, though there are multiple input, output and ground pins. I wired them all for the sake of current carrying capacity. The board is rated to 5V, but the resistor/pot setup I used (the standard 200 ohm pot and 220 ohm resistor a la OKR builds) yielded 3.5V-6.4V. I'm pretty sure it's good for it, since I've successfully run other boards 1.5V higher than max for the hell of it. I'm aware of the risks involved in going outside the spec sheet limits, and don't recommend anyone else do it. It's powered by a 3S 35C lipo to reduce the input current demand as much as possible. It isn't finished, but it's functional. I used a copper plate and mounted a brass Chi-You top cap as a high current, heat dissipating connector setup.
