Hello,
I run a small ITAD business, and I'm trying to go portable. At the moment, I use laptops running linux / dhcpd / tftpd / node.js / mongodb. Basically, network booting equipment using the laptops ethernet and performing maintenance operations via the laptops wifi.
I want to switch the laptop out for an SBC. All it really needs is ethernet and wifi, running an embedded linux image. The main thing is keeping the unit low power and running off a battery. All of this fitting into a nice case if possible and looking presentable.
I've done a lot of searching and I think the closest I have to a working product solution is a Raspberry Pi 3/4B with a PiJuice HAT. Perhaps that PiSugar may also work. The problem with the Raspberry Pi, is it's kind of overkill for the requirements, I don't need any form of output from the unit, it's all going to be API and TTY based maintenance via wifi.
The unit itself is pretty much just going to be serving out a 15mb embedded linux image via ethernet for network booting purposes. On battery power, maybe the wifi could even be turned off and then plugged into power for the maintenance. The main vision I have for this is making it super portable, but I'd love if a single unit was at least ultra conservative on the power consumption.
I see a lot of products out there, and they are definitely overkill. The idea of carrying a big chunky battery around for this is a little extreme, then having a cable from one to the other, not workable. The PiJuice HAT is probably a very convenient way to connect the two up, but the Pi's power consumption is a real let down.
Any ideas? Portability of this product is key, having a stable way to capture data is required here. I basically just want to plug it into devices by ethernet, network boot, obtain data collection via API and JSON Curl.
