There's not a lot of reason to stick with micro USB even for hobbyist projects. You can get USB-C "charging" receptacles that only breakout 6 contacts in any combination of SMD/PTH on the contacts and the mounting pins. Even in tiny quantities they're less than $0.10/ea on aliexpress. If you just want 5V you don't need to deal with PD, just stick 5K1 resistors to GND on each of the CC1 and CC2 pins (don't cheap out like the Raspberry Pi4 did and tie the CC pins together to save on a second resistor, or you'll end up with the same problems as they did). They should be just as easy to route and hand-solder and the footprint should be just as compatible with low-end pcb services as any micro-usb connector, and it will allow you to use a better USB-C cable as your power connector. If you also want the USB2 D+/D- lines broken out you can get USB-C connectors with 16-contact pinouts (everything but the SS pins). |
