In my test, using Gpy and expansion board.
(Vcc and GND pins are not included here): I2C and SPI pins

| SDA | GPIO4 | GPIO21 | Pin 'P21' |
| SCL | GPIO5 | GPIO22 | Pin 'P22' |
The original driver source from Arducam was instrumental in the creation of this pure MicroPython version.
The overall project was inspired by esparducam, but getting this to work doesn't require any SMD soldering. :)
