I’ve been trying to make a usb c Pd ups for awhile now and I’ve successfully tested my first prototype. This could potentially work with a udoo bolt as well. I would suggest a 4s2p pack at least for a udoo bolt. Link to twitter post: https://twitter.com/projectsbc/status/1301820616144814080?s=21 I’ll post a build and test video in the next few days. I’ll update this post then.
