Remora for RP2040

Would it be possible to use one or is the way the code setup make it not possible?
Might be useful for high speed encoders.

The PIO on the pico will need a learning curve for a DDS style step gen but I would think a high speed encoder interface could nearly be off the shelf...

I'm not an electronics guy, but have been looking on how to use the Pico in a real system. I've got a G540 and some old parallel port breakout boards kicking around so I'm thinking of a a carrier board with a DB25 connector. Question is, what would be the basic requirements to add to the board? 

I have not looked at the pinout for the Pico W5500 module to see if it is compatible with the A1 PicoBOB, and the B1 does not have W5500 as it was designed to be the simplest solution for GRBLHAL, but this might give you some ideas anyhow.

Thanks, this will be a great start!!! Unfortunately the W5500 uses some of the PicoBOB pins so some small routing modifications will be needed.

Came up with this using the same SPI pinout as the Wiznet module.  Should be the MVP for Remora on RP2040 and a great plugin for G540.  Placement looks good, I'll route it when I get a chance.
