T3-Mini / OTUSB-Mini
The Mini board is an embeddable tracker module measuring 1.72" by 1.12" (43mm by 28mm) and weighing 5.5 grams. The same board can be equipped with a Tracker3 MCU or an OpenTracker USB MCU, configurations referred to as the T3-Mini and OTUSB-Mini respectively.
The Mini features 13 general-purpose I/O pins (GP1 through GP12 and AUX) and four analog inputs. Connections are made through 34 contacts in two rows of 17, with a pitch of 0.1" and row spacing of 1" center to center. A mini USB type B connector provides a simple connection for a PC.
All software functions of the full-size versions are retained.
