Description

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

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 labeled A, and B. These solder jumpers provide 1k pull-ups to A channel, and B channel inputs. For use with our hall-effect motors the solder pad must have solder on it. 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. If you are interfacing with an optical encoder the solder jumpers must be left open.

When you order a buffer board, the solder pads will come already set up for hall effect encoders. DO NOT connect the A and B solder pads together. Not only will this void the warranty, it may permanently break the board.
