interface (API) sending files to sd card and ask printer to print
Goal: remote print.
I know it can be done via raspberry pi zero W, but my pi 0 just burned up and it is very expensive to get another one.
I am thinking to use a pi alternative (more expensive than PI zero W but got way more power), but does not have support. Was thinking if we have the link descriptions (i.e. pin X is power, pin Y is comm with Z protocol), I might be able to add the software myself to a third party board and communicate to the printer.
All I want is:
1. a protocol to send files to printer's SD card
2. a protocol to ask printer to print a file on SD card
So I don't need to copy files to sd cards manually.
Thanks

There are other single board computers that may work: OrangePi, Rock64 are a couple possibilities that come to mind. I would connect via USB and skip trying to plug into the back of the Einsy like you likely had with the Pi Zero. Check specific models for features you may want (like WiFi). It doesn't look you can install OctoPi on either, but OctoPrint should be installable after installing Armbian OS.

Thank you! I will try to get a sbc with wifi and try octo print.
Really want to use Prusa link because I heard someone saying prusa link works better. but I guess that is not an option.
I hope octo print over usb is as good as print from SD.

YMMV but one things for sure, streaming gets the print started much quicker than writing everything to an SD card.

I think you should take that opinion with a large pinch of salt. Prusa Link is very much a work in progress whereas Octoprint has been around for a while, gone thro various iterations and has a highly active user base.

Prusa Link has been working well enough for me.
I'm using 2 old Rasp. Pi 1 Model B rev 2 with wireless dongles that connect to my MK3S+'s via USB (not via RPi). Granted, it's lacking in many features but in my case, all I was interested was wireless remote printing and this works for me, surprisingly well.

Thank you guys!

Just for reference.
prusa uses Einsy board Rambo, and the pins matches to :
5v, GND, rx (mapped to tx on rpi), tx. The last pin (22) is mapped to reset (I guess allows board to be reset remotely).
