Awesome usb type c tool
I needed something to check the hardware side projects i create where I power then with type c decoys. This board helps me quickly diagnose and failures in design and is able to trigger output voltages for different type c spec level. The graph over time and stats feature is really useful and i am currently using this with the desktop app which is working flawlessly.
