Description
Description
Ultra simplified and economic solar power module, with minimal components.
- Charge x3 AA NiMH rechargeable baterries using small solar panel power.
- Tested with smalls 72x72mm, 130 mA, 5.5v solar panel.
- Output voltage range from 3.3v to 4.3v
- P1 module, original output format is USBC power but case allow any cable.
- This ultra simplified charger, require undervoltage protection at the controler side, usind ADC or other.
- This ultra simplified charger, don't control overcharge and asume client device will consume the overcharge. This works due to the low 130 mA charge current.
- Free GPLv3 3D printable case here
Here can see an example of wifi water level sensor that use this power module
