Smart Watch Charger (Amazfit Neo) 5.0 · 模型 52030
Currently there is no charger for the Amazfit Neo with a type c male interface. Previously I took it upon myself to make a more compact charger than the OEM and add the type c female interface. Since that project was a success I decided to do this project. To make this charge I needed to take apart a knock off charger for the Amazfit NEO linked below: https://www.amazon.com/Chofit-Compatible-Replacement-Charging-Smartwatches/dp/B08QHY6WLK/ref=sr_1_3?crid=1MY5LLZZ7OZCP&keywords=amazfit%2Bneo%2Bcharger&qid=1690655878&sprefix=Amazfit%2Bneo%2Caps%2C153&sr=8-3&th=1 While taking part that charger I found out that there is no proprietary chip for charging this device. The PCB only consisted of pogo pin connectors and a resistor going from V in to the pogo pin which i assume is to regulate charging current. It is possible to replicate this at a cheaper price if you have more experience in electrical work and soldering small components. As for the type c male interface I took apart a type c to USB A adapter and used the internals to design a case for the charger. The soldering was relatively easy just connect the ground to ground and V_in to Vbus. Although the orientation is flipped for actual watch charging. This is due to the adapter type c port no t being unidirectional for some reason. I found this out when I measured the circuit charger before assembly with a multimeter and showed the output at about 5 volts for only one orientation. 3D Printing : This was printed using PP with these settings and preparations Place Scotch tape evenly no bubbles on top of the print bed Print bed temp : 80°C Nozzle temp : 225°C Layer height : 0.2 mm Print speed : 30 mm/s Retraction length : 3 mm Retraction speed : 30 mm/s These settings usually result with an easy no issue initial print, but the second print will have issues (clogging the filament). I believe this is due to the gears retracting the filament at a different rate than that of the settings above. If you read this thank you for your time
