See > https://www.csgshop.com/product.php?id_product=195 (if we assume all > ports are available, to be confirmed) I've emailed Lucas for the driver code. No response. So, just guessing, from what I think I understand in the pdf: Needs the UBX-TIM-TM2 message. Section 3.6 UBX-TIM-TM2 works like a TICC on EXTINT0. Section 3.6 The figure in 3.6 looks to be directly from the u-blox doc: u-blox8-M8_ReceiverDescrProtSpec_\(UBX-13003221\).pdf Section 19: TIMEMARK. That also describes measuring EXTINT0 with UBX-TIM-TP2. So I think that is nailed down. Sort of. The u-blox doc says UBX-TIM-TP2 is supporting on firmware verion 15 up to 23.01. Looking at the csgshop page, I can't tell if pin 4 (FREQ PHASE IN 0) is the same as EXTINT0, but that would be my guess. The firmware version also not specified, but csgshop tends to ship fresh parts. $189 is real sticker shock for a u-blox 8. All academic unless Lucas shows us his code.
