6.5 USB HOST
The USB hosts and the Ethernet are controller by the iMX233 controller.
Important! The USB of OLinuXino-Micro can communicate directly only with High-speed or Full-
speed USB devices. The majority of keyboards and mice are low-speed devices.
A good solution for plugging a keyboard or a mouste to the Micro is to use a USB hub between
your device and OLinuXino-Micro - using such a hub has the additional benefit of providing
additional USB slot (which can be used for example to mount flash memories etc.).
The signals follow the familiar and standard USB host pattern:
6.6 PWR Jack
The power jack used is the typical 2.5mm one used by Olimex in most of our products. You should
provide 5 volts at 1A maximum to the board.
More info about the power supply can be found in chapter 5 of this manual
