Can the Tokymaker power up a PCA9685 power board. Will it need a separate power source if it can. Thanks. I am working on a design for your board.

The motor shield should replace the need of a PCA9685, it should come with some power port. 

Hi Bill, Actually If you want to extend the Output ports of the tokymaker to power up many motors, you can use our Motor Shield. That is capable of driving 8 big servo motor + 4x 2Amp DC motors. It is all connected to one Output and we have the blocks for that already added in our coding platform https://create.tokylabs.com44

Hope you find this info useful!
