There it is, the new revision of Replicape. This revision is more compatible with the new BeagleBone Black that has a built in eMMC. There are a lot of other changes as well on this revision. The most important is the moving of the stepper motor connectors to the outside of the receptacles so removing is no longer necessary. Furthermore there is no need for a separate 12V and 5V power supply. You can now power the whole board with a single 12 to 24V PSU. Other things to mention is a major upgrade to the tracks and connectors for the heater cartridges and heated build platform, the addition of a fuse and finally a new color so that there will be no doubt which BeagleBone this belongs to : )
I’ve gotten a lot of help from Dirk Eichel on this revision, especially on the fat power tracks, the addition of a freewheeling diode across the MOSFETs to suppress voltage spikes and grips to reduce noise on the ADC lines.
Although there are a lot of nice changes, there has also been a lot of work put into keeping the cost down. The total cost of the board is the the same (BOM is ~$90).
I’ll give it a couple of days to get input from the community both on bugs in the layout/schematic and feature requests. Have a look at the RevA2 tag of the repository.
