While I’ve been mostly happy with the NES USB power board I made a couple years ago, I have noticed power sags when the console is loaded down with 2 wireless controllers, and an Everdrive. Some of that could be due to a crummy USB cable, or the resistor (or dead short) on the data pins not playing nice with my 3A charger.
Nonetheless, I decided to upgrade the design of the board to use the USB type C Power Delivery spec. Assuming an adequate charger and cable, this should guarantee 5V@3A at the input to the console. Totally overkill, but the future is now, old man. 🙂
I haven’t sent the gerber files off for production yet, but I can’t wait to give this new design a test…
