Description:

This is a breakout board based on US Digital's LS7366R quadrature counter IC. The LS7366R is designed to interface directly to an encoder output such as the hall-effect encoders on our IG32, IG42, and IG52 gear motors. Equipped with a SPI interface, the LS7366R makes is simple to monitor the position of the motors and total distance traveled. The LS7366R can be configured to work with a quadrature output or a single pulse and direction.

Depending on your encoder setup, this breakout board has a series of solder jumpers located next to the encoder input headers. To interface directly to our encoder equipped motors, the solder jumpers must be bridged to enable the required 1k-Ohm pull-up resistors. If you are interfacing with one of our optical encoders the solder jumpers must be left open.

Features and Specifications:

• Opperating Voltage: 3V to 5V*
• Dimensions: 0.77" x 2.50"
• 32-bit programmable counter
• 32-bit data register and comparator
• 32-bit output register

Solder Jumpers

There are a series of solder jumpers next to the encoder headers. These solder jumpers provide 1k pull-ups to the LFLAG, A channel, and B channel inputs. For use with our hall-effect motors the solder pads need to be connected. The output of the encoder is grounded as it senses the rotating magnet. These 1k pull-ups are required to pull the signal high so that the encoder pulses return to 5V after the magnet passes the sensor.
