I recently purchased and assembled the MiniPOV4 (Jan/2020). Unfortunately when I power it on nothing happens: none of the LEDs blink, and there is no other indication that anything is happening.
Following the suggestions found in the forum, I tried a number of things:
- visually inspected the solder work for any issues (see attached)
- used new batteries and measured their voltage
- measured a voltage from the batteries to the board when in the ON position
- measured the voltage on Pin 7 of the socket to make sure that the IC is powered (it is).
- plugged it in to the USB port but did not see the device register (running MacOS 10.14.6 Mojave).
Thanks!
