ASUS Zenwatch 3 Snap in Charge Cradle

thingiverse

This is a snap on, (Rather than magnetic), charging cradle for the ASUS Zenwatch 3. Electrical connections of course have to be installed. Here is the connection key, looking at the back of the watch, connectors at the top; Top Left - Ground Top Right - Green USB Wire Bottom Left - White USB Wire Bottom Right - +5V (If needed; If you look at the end of a USB plug, with the gap on the end facing up, the connectors are Ground, Green, White, +5V.) For the connectors, I used Pogo Pins, which are spring loaded pints used for testing circuit boards. These are the ones that fit in the holes. (Part of the reason for making this project was the poor connections on the rounded stock pins. These pins have very small claws on the tips to help connect, and they have more pressure against the contacts. (I used these - https://www.aliexpress.com/item/32795357197.html?spm=a2g0s.9042311.0.0.27424c4dN1lBmk) Magnets MAY be possible while still accomplishing this, but I haven't gone down that road. (It was hard enough to get the pin holes in the right place!!! I used quick setting epoxy to hold the pins in place. (I didn't risk putting it down the holes, just on the back.. So far.) I soldered the wires onto the backs of the pins. Obviously, there is room for improvements!! The first improvement needing made is the pins themselves, obviously, having them stick out the back almost 10mm isn't very nice looking. A simple back plate would help. I may add this soon.
