Hi Everyone,

Does anyone have any experience using the HSM4/6 in a custom circuit/PCB with the Raspberry PI, I am in the process of designing one and am struggling to find any reference documentation. So far I have only been able to find the pinout of the connector.

Any examples or advice would be very helpful.
