For other platforms, please visit the guide for CircuitPython on Linux to see whether your platform is supported (https://adafru.it/BSN). © Adafruit Industries https://learn.adafruit.com/adafruit-mini-gps-pa1010d-module Page 17 of 35...
  • Page 18 For UART, you have two options: An external USB-to-serial converter or the built-in UART on the Pi's TX/RX pins. USB-to-Serial Cable Interface Here's an example of wiring up the USB-to-TTL serial converter (https://adafru.it/dDd), and the FTDI serial TTL-232 USB cable (https://adafru.it/dNN) (also available in USB-C (https://adafru.it/H3d)): © Adafruit Industries https://learn.adafruit.com/adafruit-mini-gps-pa1010d-module Page 18 of 35...
