I cannot find any details of the capacitor or resistor values for the new encoder board (see image).
I have the AS5040 chip, but I cannot find a BOM or schematic for the other components.
I am using DC motors, so I need this encoder.
Can anyone point me in the right direction for a schematic or BOM?
Cheers,
Brian
@azisi has done a very good job, documenting everything at https://gitlab.com/librespacefoundation/satnogs/satnogs-rotator-controller-encoder There is a BOM and the Kicad project of the encoder.
To second what @surligas just wrote: Specifically have a look at the releases of satnogs-rotator-controller-encoder. There you can also find a nice InteractiveHTMLBOM called SatNOGS-Rotator-Controller-Encoder-ibom.html which is great during assembly.
Thanks for the replies. I guess my question is that in the image below from the build sequence (https://ohai.satnogs.org/project/satnogs-rotator-v3-mechanical-assembly/hardware/) shows the new version of the DC motor encoder. The image from my first post shows a new encoder board based on the AS5040 chip. The image below shows the prototype board mounted above the DC motor drive axis. I have the board and the associated 5040 chip. The problem is that I don’t have a schematic to figure out the component values, nor do I have an stl file for the bracket to hold the board as shown below.
I am wondering if I should abandon this route, get the old 5601 encoder and the old encoder board and go that way, versus using the items I now have.
I am guessing that it will not be straight forward as to how I can connect the new encoder board to the existing Satnogs Controller?
Any suggestions as to how to proceed?
Hey! The DC motor encoder (AS5040) that you use isn’t released and the ohai - assembly guide never updated, sorry about this confusion. The released version of encoder is this with AS5601 IC. In wiki - SatNOGS Rotator Controller: Encoders and wiki - SatNOGS Rotator v3:Assembly you can find all the parts which are needed for the encoder.
