How to Network Boot a Raspberry Pi Without a MicroSD Card

https://www.makeuseof.com/tag/network-boot-raspberry-pi-without-microsd/

One alternative is to boot from a USB device instead, but with the release of the Raspberry Pi 3 B+, things have improved. Now you can boot multiple Raspberry Pi’s over Ethernet, from a central server.

 

Presumably CM3 Lite could also accomplish something like that?

Allo's Revolution is a USB-input DAC and not at all compatible or interchangeable with the Katana. Will it be better? Allo learned a lot of new tricks in developing the Katana and has added a number of additional tricks since and will apply them liberally on the Revolution. BUT the Revolution will have less flexibility in providing it good power. AND it will be a significantly less expensive DAC, which tells you a bit about how Allo is positioning it.

But the company has also worked with third-parties, and Gumstix, an Altium company, has unveiled four different carrier boards for the Raspberry Pi Compute Module 4, as well as a convenient CM4 to CM3 adapter board that enables the use of Raspberry Pi CM4 on all/most carrier boards for the Compute Module 3/3+.
