I’ve looked for breakout boards for a magnetometer (Compass) module) I need, AK8963 but they are expensive $25 each.
I thought perhaps I could buy the chip (surface mount) and make a board, but find they’re a challenging small size. The N is app 2x2mm and has edge connectors 4 by 4, that I may with care be able to solder and check $5ea.
I bought the C type but these have dots for connections on the bottom (14) and later I found they are app 1.6x1.6mm. $0.70each Almost too small to see (Amazing) (IPHONE compass)
Is there any way I will be able to use them?
