I just sent off a first attempt at an adapter board that includes the following:
- The Pi Zero 2W footprint (on the underside of the board, to save space)
- A 4-port USB hub, with connectors (QWIIC style, though of course not compatible) to bring the connections where needed. There’s a small header to interface with the test points (I’m not sure whether I’ll use low-profile pogo pins, or just wire wrap): SL2.1A | CoreChips | Price | In Stock | LCSC Electronics
- A Pololu 5V boost for power: Pololu - 5V Step-Up Voltage Regulator U3V40F5
- A Sparkfun Thing Plus, with a bunch of connections for some external sensors: SparkFun Thing Plus - ESP32 WROOM (USB-C) - SparkFun Electronics
- Various headers to break out pins in case I made a mistake and need to get out the wire wrap, or for things to connect later.
It should show up in hopefully ~2 weeks, then I’ll get to build and test it.
