Gear ratio 298:1
Magneic encoder, 2 channels, 7 PPR
This particular DC motor comes with a 1:298 gear ratio and uses 3V nominal power. The gear ratio will not affect the current draw but does change the torque and RPM. See below for the no-load/rated/stall current, RPM, and torque for a range of ratios!
Provide 3V DC (nominal) to the white and red wires - these connect to your motor driver and can be PWM'd for speed adjustment and direction by using an H-bridge.
Connect the black wire to your microcontroller ground pin, and the blue wire to 3-5V DC using whichever voltage your microcontroller uses. Then you can read the hall effect outputs on the yellow and green wires.
Basically, you just want to interrupt on one of the encoder pins, use count the time since the last interrupt, and multiply the count time by 14-counts-per-revolution and the gear ratio.

The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
