JACDAC Hardware DDK ?

@peli , I’m looking for your hardware specs for the peripherals for jacdac system. You have them for the new USB connector but I need the distances and locations of the holes in the boards of each sensor/actuators. Or are they mandated in form factor ? I’m talking about those gold ring holes in each peripheral board. Can you point me to DDK documents ? Thanks. https://github.com/microsoft/jacdac-ddk/blob/main/connector/JACDAC_PCB_Edge_Connector_Drawing_JD-PEC-01_rev_01.pdf
