Description
The ZERO2GO OMINI is a pHAT sized, auto-switching power supply extension board that allows you to power your Raspberry Pi from a wide range of possible inputs such as a power bank, solar panel or car battery. Compatible with all Raspberry Pi models that are equipped with the 40-pin header; including the A+, 3B+ and Zero models.
Features
- Three separated input channels (each accepts 3.5~28V DC).
- Auto step-up or step-down to output 5V for powering Raspberry Pi.
- Auto switch input channel (one with highest voltage takes the priority).
- Gracefully turn on/off Raspberry Pi with single tap on the button.
- Fully cuts power for Raspberry Pi and all its USB peripherals after shutdown.
- Long hold the button to force power cut, when OS loses response.
- Monitor the input voltage on each channel (via software).
- Shutdown Raspberry Pi when input voltage below preset threshold.
- Recover Raspberry Pi when input voltage exceed preset threshold.
