eDRUMin revision changes

[MWJT42]

Is there a page somewhere documenting the changes in the eDRUMin revisions, please?

I believe there is:

- ED4 (plastic)
- ED4R2
- increased trigger headroom, higher USB power like ED10
- ED4R3 (metal)
- ?
- ED4 rev 4
- ?

- ED10
- ED10R2
- increased HH sensitivity, more USB power

I'm selling a ED4 (rev 1) and people are asking about firmware support, and capabilities relative to later revisions.

It's all documented in this forum.

ED4 (plastic) -- original device
ED4R2 (plastic) -- much improved input circuitry taken from ED10 and more power for pedal input.
ED4R3 (metal) improved hihat sensitivity
ED4R4 functionality the same as ED4R3, but had to design with some new parts that were no longer available.
