I tested mine too with the latest release (4.5.4) and it seems to be working fine. Note that there hasn’t been any changes to the firmware since the stable release, so there’s no need to test the dev-firmware as it’s just the same as the stable one.
Update: I pressed on the connector and that made it stop working, with the same error on reset(). I then disconnected the sensor and reconnected it, then it started working again.
I also noticed that it sometimes fails to detect the sensor. I think this can be fixed by increasing the delay after toggling the reset/pwdn pin. This particular sensor board connects the reset signals to an LDO, so it may need more time to settle. I have a PR here to do just that, we’ll test this more and discuss to see if we merge this or not. In the meantime if you have more issues with this board let us know.
