EduMIP parts: optical quadrature encoder, where to buy?

Good afternoon,

Does anyone know where I could buy spare parts for the BeagleBone Blue EduMIP kit (https://www.renaissancerobotics.com/eduMIP.html)?

More specifically, I wanted to know which is the exact optical quadrature encoder used here:

If someone could provide me a link to Amazon, Banggood, Digi-key, etc with the exact same part, I would really appreciate it.

Thought I’d answered this, but I don’t see it. The motor assembly comes from Wowwee and I don’t think the components can be purchased separately. Tons of different encoders available work fine (need to support 3.3V).

Here’s an example of what I’ve used: https://www.pololu.com/product/1523
