USB

The Pigeon computer is equipped with three USB host ports. The total current draw from all USB +5V outputs and the +5V DC connector should not exceed 1A. More details about power control can be found in the Power control section.

GPIO6 is connected to the RESET signal of the USB hub and the Ethernet controller (LAN9514 chip). The RESET input assertion (low state) time must last for at least 1 μs.

The fourth USB port, labeled 'USB DEVICE', is intended solely for system updates.
