The T3-Micro is a Tracker3 in a USB dongle form factor, presently in beta testing.

TRRS connector

Pinout (3.5mm TRRS connector, starting with tip):

Pin Function
Tip Audio out (to mic)
R1 PTT (open collector)
R2 Audio in (from speaker)
Sleeve Ground

The T3-Micro has no jumpers. Handheld PTT mode, required for most handhelds except those by Kenwood and most Chinese imports, is set using the command HTPTT ON, or the "HT PTT" checkbox in otwincfg.exe located in the Radio Interface panel. When setting the option in otwincfg, you must first write the new configuration before the change will take effect.

Firmware build 56471 or later must be loaded for the HTPTT command to function.

The NMEA pass-through option (NMEAPASS ON or "NMEA P/T" in otwincfg) can be enabled to pass NMEA GPS data through from the on-board GPS receiver to the host. This applies to both console mode and KISS mode.
