This is 32 GB RAM Rock 5B running an #Ethereum Super Node (L1+L2 Optimism snap yncing).

L1: Geth+Lighthouse
L2: op-geth+op-node

TL;DR: We need more testing to get a stable image but these devices are really promising, particularly for running Super Nodes.

First things first. We got it from a new supplier (Arace), a model called "Blue Edition". See it here:

https://arace.tech/products/radxa-rock-5b-blue?variant=42502489931956

252 € + 70 € at customs.

No accessories are available here (Case, heatsink, power supply, etc).

Contributing to the Ethereum decentralisation by providing OS images that turn ARM64 boards into full Ethereum nodes.

Other suppliers (such as All Net China) have a 32 GB RAM option as well but it is currently sold out:

Here you can buy all necessary components to get a decent set up.

We ran into stability problems right after running an L1 node. Allocation memory is a known issue in Armbian.

There are other factors that may lead to these issues such as PD and drivers for the board and disks.

It may take a while to get a stable image but these new devices are particularly interesting to run Super Nodes.

Official Radxa image seems to work OK.

Another board is on its way to start testing (Orange Pi 5 Plus 32GB) so we'll get more options soon.
