Product Overview

This is the revolutionary Lamprey Absolute Encoder. It is a 10-bit absolute encoder specifically designed in collaboration with 221 Systems for the next generation of Swerve and Steer. It features a large hollow bore and is great for swerve drive steering, arm joints, or anywhere you need to directly measure your output without being at the shaft end.

It features a custom PCB with the sensor elements and a custom ring magnet to use as a sensor target. The ring magnet is designed to pilot on the flange of any of our 1.125" OD bearings. To install it, glue to any rotating surface or 3D print a custom hub. The magnet can be sensed from either side of the board.

The interface and included cable use a 0.05 in. 2x5 pin header and IDC cable. This lets you plug directly into a Talon SRX speed controller and interface with other popular components for FRC competition use.

The encoder can be acquired as the encoder only, just the magnet, or a bundle which contains the encoder PCB, the ring magnet, the 10 pin SRX data cable and the mounting hardware used in the Swerve and Steer.
Note: As indicated here it is necessary to cut pins 5 and 7 when using this sensor directly with a speed controller to prevent the sensor from restarting intermittently.

Pinout:

The Lamprey uses a 10-pin IDC cable arranged in a 5x2.
Pin 9: SCK Pin 7: UART -Tx Pin 5: UART - Rx Pin 3: Analog Out Pin 1: Reset
Pin 10: Ground Pin 8: MOSI Pin 6: PWM Out Pin 4: MISO Pin 2: 5V DC In

Specifications

  • Output: 10-bit Analog: 3.3v or 5v, 10-bit PWM: 1000uS-2000uS, UART, 5v
  • Voltage: 5V

    Seems to be a great solution for measuring rotation on through shafts

    We are using this for what most probably are, measuring rotation on a swerve module. The magnets are a little more brittle that expected, we broke one in half on a light press fit and had to order another to replace it. Glad we are close enough for 1-2 day shipping. Thanks!
