As I was tearing my MKS Sbase installation down, I thought that maybe I'll test the SBC mode while I'm at it. This means adding a raspberry pi to the setup with a custom SPI cable. And after some fiddling the setup seems to work. The biggest improvement is the networking; when using the Sbase's ethernet, it's slow (upload about 70kb/s) and it allows only one connection at a time. That's because of limits of the CPU on the board. So in SBC mode I get:
- Wifi
- multiple connections
- speed (5.5Mb/s)
Now I'll just have to make an enclosure for the raspi, currently just hanging by the wires... .
Btw I'm powering the raspi from 12V, using a small DC-DC step-down converter fixed to output 5V. So no need to use a usb charger
