Mocoder is a 12-bit magnetic encoder (4096 steps). Use it to sense the position of any object that needs to rotate continuously, like an RC servo, wheel, gear-train, or some robot joints.
This version of Mocoder consists of just the breakout board for the AS5600 IC. A complete version that includes the PCB, nylon housing, magnetic spindle, SMD header, and ball-bearing is available here.
To use the encoder, add power (5V/3V selectable), hook up the output to your ADC, and rotate a diametric N35 magnet 1mm above the IC. It is also possible to read out values as Pulse Widths (eg. using Arduino pulseIn command), or use i2c to read values direct from memory. All of the AS5600 pins are broken out for user access. Wires can be soldered directly to the board, or use an SMD header to Mocoder for a quick connect option. Again, try the full version for a complete solution that includes the magnet, spindle, smd header, ball-bearing and sensor board.
Mocoder was first created as way to make RC servos have both position sensing and continuous rotation. It is used as part of the Moti Smart Servo project. However, during Moti's development it became clear that Mocoder could stand-alone, and so I'm selling some here on Tindie. This way if you have a different application in mind, or simply want to create your own Smart Servo you can do so. In fact, there is detailed documentation on how to modify a servo with Mocoder in the sidebar.
Most encoders are either cheap, low-resolution, mechanical types, or they are expensive ($40+). Mocoder is affordable, while offering higher resolution than some more expensive versions.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I develop code, and custom hardware, with a focus on embedded systems and robotics. I've been doing this both for clients and on my own projects for 15 years or so. Now I'm exploring commercializing these designs, by selling here on Tindie. Feel free to get in touch.
Also, please note that I'm from Toronto, but products ship from Macrofab in Houston.
