Yes, basically. What Im saying, is that no matter which one you pick, you will get the same board. If you want a wiring harness, its gonna cost extra. If you want a special wiring harness (trackabll) its gonna cost u even more.
If you buy the 29 dollar board, and BYO wiring harness, you still get the functionality of the trackabll, just you had to make your own wires. He's selling the wires basically.
