POLOLU ROMI ENCODER PAIR KIT, 12 CPR,
3.5-18V
USER'S GUIDE
PINOUT AND INSTALLATION
The encoder board is designed to be soldered directly to the back of the motor, with
the back shaft of the motor protruding through the hole in the middle of the circuit
board. One way to achieve good alignment between the board and the motor is to tack
down the board to one motor pin and to solder the other pin only when the board is
flat and well aligned. Be careful to avoid prolonged heating of the motor pins, which
could deform the motor case or brushes.
We currently have two boards that the these encoders can directly plug into: the Romi
32U4 Control Board and the Motor Driver and Power Distribution Board for Romi
Chassis. The encoder pins need to be installed pointing down toward the chassis in
order to be able to plug into this board.
The Romi Encoder can plug directly into
Romi 32U4 Control Board with LCD on a
the Motor Driver and Power
Romi chassis.

- Page 2 For robots not using these boards, it might be more convenient to install the board and pins facing up and connect to them with a cable made from our wires with pre-crimped terminals. The included low-profile headers are still long enough to work with our pre-crimped jumper wires.
- Page 3 If you do not care about compatibility with existing or potential future boards, we recommend soldering wires directly to the encoder or installing a standard-length male header that works better with cables made from our wires with pre-crimped terminals. A standard-length straight 0.1″ male header allows for compact cable connection. Once the board is soldered down to the two terminals, the motor leads are connected to the M1 and M2 pads along the edge of the board;...
- Page 4 Encoder A and B outputs of a magnetic encoder on a high-power (HP) mini plastic gearmotor running at 4.5 V. The board’s six pads have a 0.1″ (2.54 mm) pitch, so they are compatible with common 0.1″ connectors, or you can just solder individual wires directly to the board. Once the board is soldered to the motor, the magnetic encoder disc can be pushed onto the motor shaft.
