Connector Replacement Recommendations

Recommend a replacement for @J1.

flux

Here are solid library-available replacements for J1 (TYPE-C-31-M-12). I picked parts suitable for power-only use (VBUS/GND/CC1/CC2) and SMT, right‑angle, top-mount styles.
Recommended replacements for J1

Table

ReplacementWhy it fitsNotes
TYPEC-304-BCP16Datasheet: 16‑position Type‑C SMT R/A receptacle; 3 A capable. Good match for power‑only wiring.Footprint likely similar to TYPE‑C “16P” styles; verify pad/stake pattern before swap.
USB‑C 2.0 ReceptacleDatasheet: USB 2.0 top‑mount SMT receptacle; documented recommended PCB layout. Works well when only VBUS/CCs are used.Not guaranteed drop‑in; check shell tabs and pad pitch vs current footprint.
124018312112ARobust Type‑C receptacle (USB 3.x capable).Likely different pad map; choose if you can accept a footprint change.
Notes and checks
  • Current part package tag shows “USB16‑TYPEC8.94x7.35” and 24 pads listed in the datasheet entry; many power‑only connectors use 16 signal pads plus mechanical stakes. Please verify stake hole and pad spacing against your existing footprint.
  • Best practice: include TVS protection for USB data lines if you ever enable D+/D− in a future spin.
Would you like a drop‑in only swap (no layout changes), or are small footprint tweaks acceptable? If you prefer drop‑in, I can check pin/stake positions and propose the closest match, then replace J1 for you.

according to the datasheet, are all the GPIOs on U1 compatible with SPI?
