Rockchip RK3588 Pico-ITX board launched with four-node cluster box (Crowdfunding)

The Mixtile Blade 3 Pico-ITX single board computer (SBC) powered by Rockchip RK3588 processor has now launched on Crowd Supply with either 8GB or 16GB RAM, and an optional four-node cluster box with a built-in PCIe switch designed to accommodate four Mixtile Blade 3 boards.

The board also comes with up to 128GB of storage, two 2.5GbE interfaces, HDMI 2.1 output, HDMI 2.0 input, USB 3.2 Gen 1 USB Type-C ports, as well as a mini PCIe Gen 2 for expansion and a 30-pin GPIO header for expansion, as well as U.2 edge connector with 12V, PCIe x4 Gen 3 and SATA signals to interface with other Mixtile boards and build clusters.

As discussed in the initial announcement, Mixtile does not directly offer Linux support, but instead, runs a Linux container within the Android 12 image preloaded on the board. What’s new is the board will ship with a large heatsink in a design similar ODROID-N2+ board for instance. The documentation does not seem to be up yet, but the support forum is.

The company says it’s possible to create a cluster of 75 Mixtile Blade 3s in a 19-inch 2U chassis with up to 600 processor cores while drawing less than 1500 W of power. For smaller deployments and evaluation, there’s also a four-node cluster box to create a neat system instead of going the usual acrylic case and spacers setup.

Typical applications for the Mixtile Blade 3 include on-premise high-performance servers, low-power HPC cluster nodes, advanced HMI systems with extensive image processing capabilities, compact computing clusters, high-density server integrations for MLOps deployments, big-data storage and processing for 3D graphics and AI applications, edge computing for autonomous vehicles, real-time video streaming and more.

The Rockchip RK3588 Pico-ITX board is available on Crowd Supply for $169 with 4GB RAM and 32G eMMC flash, and $259 in 16GB/128GB configuration. The 32GB RAM model is not offered yet, and I don’t think any company is currently selling RK3588 hardware with 32GB RAM despite the various announcements to the contrary. A $239 pledge is asked for the four-node cluster box. We don’t have many details about it, except “the batteries are not included”. So I’d assume there may be a UPS function too? Shipping adds $10 to the US, and $20 to the rest of the world, with deliveries scheduled to start by the end of October 2022.
