The TinyPilot power connector splits the Raspberry Pi 4B's USB-C port into a power input and a data output.
The Raspberry Pi 4 requires 3 Amps of power for stable operation. A computer's USB port provides less than a third of that. The TinyPilot power connector allows you to connect your Pi to an external power source so it can receive the full 3 Amps it needs.
The connector ensures that your Pi stays running even when the target computer shuts down. This allows TinyPilot to power down its target computer without risking an unplanned shutdown of its own power.
Critically, the TinyPilot Power Connector prevents damage to your hardware. Without a device like the TinyPilot Power Connector that prevents reverse current, power can flow incorrectly between your devices and cause permanent damage to your Pi or your motherboard.
