So what am I attempting to do Most of the work revolves around USB Type C power delivery. Building new USB power modules that use Type C connectors and thus can deliver more than the 5-7W of a typical USB connection. This also applies to the Brick Controller which will be able to deliver more power to the motors.
Here is a 3D model of the test prototype of the Type C power module. From this design it looks like I will be able to maintain the 1.5 x 1.5 inch size of the previous modules. This is the area contained inside the four mounting holes. I have added a small PIC18F area(to the right) so that I can monitor the STUSB4500 during the test process, In the end the configuration will be programmed into NVM on the IC and this wont be needed.
The other project is the new brick controller. Besides adding Type C, I want to add an MP3 player and storage for music that appears as a USB drive, as an option. With USB HID and MSD, MP3 and BTLE interface, a PIC18F is not going to make it. So I am moving this design to a PIC32. Some what of learning experience, since the Harmony Configurator is taking some time to get use to. I am prototyping the design using a PIC32MX470 Curiosity development board for now. With two expansion slots it should make it easier to do. Here is a stock picture of the development board.
