Hi everyone,

Does anyone know of an evaluation board or reference design for Quectel RG50xQ modules that exposes the GPIO_32 1 PPS output (SIB9 timing signal)? Ideally, something that breaks out this pin and can provide the 1 PPS signal for an external timing system. This is for precision timing or synchronized applications.

Dear @khan
Which module do you use? I can share reference design document to you.

Dear @silvia

We are currently in the R&D and component selection phase. Our purchase is strictly dependent on 1 PPS (SIB9) availability. Please provide the recommended model number and Hardware Design documents confirming that GPIO_32 supports this 1 PPS output so we can proceed.

Thanks alot

Which R5xx does have a PPS pin for SIB9?

Dear @MaciejMuehleisen
What do you mean of R5xx?

I meant RM5xx meaning modules from the RM500, RM520 or RM530 series.
