Designed for direct interfacing with hall-effect and optical encoders, it offers a high-speed SPI interface for accurate motor position and distance monitoring. Configurable solder jumpers enable compatibility with various encoder types, making it a must-have for professionals demanding precise, reliable encoder data in robotics and automation. ## Description This is SuperDroid Robot's TE-183-002 encoder buffer 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 from an encoder or a single pulse and direction from a single sensor. 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 for the motors. If you are interfacing with one of our optical encoders the solder jumpers must be left open. Documentation, support, and sample code can be found on SuperDroid Robot's website. Review: Just what I was looking for! - This board does what it says, and it does it well. It's kind of pricey in my opinion, but if you absolutely positively cannot miss a pulse on either of two axes, it's the way to go. (It has a minimum quadrature period of around 52ns or so, meaning you could hypothetically read something like 24000 revolutions per second on a 200PPR encoder? Works for me!) No more fussing with Arduino hardware or pin-change interrupts. Honestly, the only thing that annoys me about the LS7366R is that it expects the index signal to be inverted, i.e. active-low (which none of my US Digital encoders do), and you cannot configure it in software (unlike the LS7366, which lets you set either a negative or positive index in MDR0 bit 6). Still, that's not SuperDroid's fault - this board does exactly what it's supposed to do - and it's not really a pain for me to throw an inverter into the circuit. Don't forget -- if you need a simultaneous reading of both axes, activate both SS lines at the same time and send a 'copy CNTR to OTR' command to lock in the values on both devices, then read each OTR value at your leisure. These chips will do SPI at over 4MHz but that's still too slow to read one buffer and then the other buffer. Review: Pricey, but works great! - Works great, but at almost $50 is a little overpriced for what you get. It doesn't even come with headers/connectors. I will say that superdroids has great documentation on it. ## Features - 32-bit data register and comparator - 32-bit programmable counter - Dimensions: 0.77" x 2.50" - Opperating Voltage: 3V to 5V ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.0 out of 5 stars 2 Reviews | ## Images ![Dual LS7366R Quadrature Encoder Buffer - Image 1](https://m.media-amazon.com/images/I/51qFTNfBg6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just what I was looking for! *by J***N on September 13, 2016* This board does what it says, and it does it well.
