N20 DC Motor with Magnetic Encoder - 6V with 1:50 Gear Ratio _MAKE_DISPLAY_PAPER Comes with a 2 pin

Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard)

But these are very fine calipers as well

Compact device at 3" / 80mm long

Easy e-paper finally comes to microcontrollers

N20 DC Motor with Magnetic Encoder - 6V with 1:50 Gear Ratio _MAKE_DISPLAY_PAPER Comes with a 2 pinThe first step in a robotics project is to get a motor spinning. Once you've done that you quickly learn that not all motors go the same speed, even if they are the same part number! There are always variations that relate to voltage, environment, and manufacturing changes. So, the second step is to figure out how fast it's going! Turns out that's not so easy, but the best way to get started is to add an encoder wheel and an optical or magnetic
