T3-Micro
From ArgentWiki
The T3-Micro is a [Tracker3] in a USB dongle form factor, presently in beta testing.
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 |
In place of the HT jumper used on the OT3m and T3-Mini, the T3-Micro uses the command HTPTT ON/OFF to set the PTT mode. Most handhelds, except for Kenwoods and Chinese imports like Wouxon, Puxing, and Baofeng, should use HTPTT ON.
