NASR-M first prototype production

Yesterday, I sent the initial NASR-M prototype for production to JLCPCB. Hoping there will be no obvious blockers and I'll be able to bootstrap Linux with no re-spins. I want to bring the board up circuit by circuit to know precisely what works and what doesn't.
Since I have no X-ray inspection equipment at home, my PCB assembly list includes all the BGA components. The board will be populated with SOC, DRAM, EMMC chips, and small bypass capacitors to save me time on soldering in tiny 0201 and 0402 parts. There are about 200 of them, so it's a substantial time saver. It's time to consider investing in an "assembly" microscope and nice probe holders.
