From the HRM connector header, I could only identify HRM_SDA (D24) and HRM_SCL (D32). I guess the other pins (HRM_INT and HRM_POWER) are gated. It’s hard to trace without removing components which likely damage parts.
Gordon already answered that the schematic is not available and no answers from anyone for my question about the HRM header pinout, so my guess is Bagle.js’ software is open, but not the hardware.
I really want just one more pin. Can anyone just let me know whether any of those pins, HRM_INT and HRM_POWER or both, are exposed and accessible on the PCB and where they are if accessible?
Thanks.
