The T3-Micro is a Tracker3 in a USB dongle form factor, presently in beta testing. It includes an on-board GPS receiver, and its only external connections are USB and a radio port. Power is provided over the USB connector. The T3-Micro can be connected to a PC, run from a cigarette lighter USB adapter in a vehicle, or powered standalone with a USB battery pack.

Documentation is provided through the support wiki.

No pre-built cables are presently available. A 3.5mm TRRS plug is provided with each T3-Micro so you can build your own cable.
