is there any documentation who shows the relation between RPI header pins and the gpios on the “outer-ring” of the CF3 module for WP77 ?

\_ for wp85 : [GPIO for CF3 - Legato Docs](https://docs.legato.io/latest/sampleApps_gpioCf3.html#pinMapping)

following this indication.

> Raspberry Pi header pin 7 is labeled as WP\_GPIO\_3\_lvl in the schematic which can be traced to WP\_GPIO\_3 and finally to GPIO24 on the “outer ring” of the cf3 module. So 24 is the GPIO number that you want to use in your code. Aside from that, your code won’t appear to do much because you turn the GPIO on and then immediately turn it off. Maybe take a look at the [heartbeat app](https://github.com/mangOH/Heartbeat) for a demonstration of LED blinking.

RPI pin 7 = CF3 pin 24 = le\_gpioPin24 … confusing
