Stealth is a Canadian company that specializes in rugged displays, computers, and other ruggedized electronics for the industrial, defense, and marine markets. The company published a press release for a new rugged fanless mini PC equipped with a dedicated NVIDIA GeForce graphics card, and older Intel 6th and 7th Generation Core i5, i7 & Xeon processors.
But as I browsed their website, I also noticed a compact “industrial IoT device” with a rugged enclosure called SIOT-50 that appeared to be fitted with an off-the-shelf Arm Linux SBC.
Let’s look at the SIOT-50 specifications and photos to find out which SBC that may be:
- SoC – Rockchip RK3288 quad-core Cortex-A17 processor with Arm Mali-T764 GPU, H.264/H.265 video hardware decoder
- System Memory – 2GB DDR3
- Storage – 16GB eMMC flash, MicroSD card slot
- Video Output – HDMI up to 4K @ 30hz
- Audio – Realtek ALC4040 audio codec, 3.5mm audio Line Out jack
- Networking
- Gigabit Ethernet (RJ45)
- Built-in 802.11 b/g/n WiFi 4, Bluetooth 4.0 + EDR with optional antenna
- USB – 4x USB 2.0 ports
- Misc – Power LED, drive/storage LED
- Power Supply – 5V/3A via micro USB port
- Dimensions – 92 x 68.3 x 33.35 mm (fanless rugged aluminum chassis)
- Temperature Range – 0 – 40°C
- Weight – 540 grams
The specifications match exactly the ones of ASUS Tinker Board S single board computer, and indeed. the company confirms the board is used in the description on the product page. Both Android (Nougat) OS and Debian Linux are provided for the tiny rugged computer, and Stealth expects SIOT-50 to be used in various industrial applications, including process automation, mobile resource management, fresh and waste water management, and smart grids.
Stealth SIOT-50 industrial IoT device is sold for $545, which looks really expensive for a Tinker Board S with a metal case, but I assume long term supply may be provided for industrial consumers. Further details may be found on the product page.

I think that 2020 is a bit late to invest for the long term in armv7. No doubt the RK3288 is an excellent device, I’m still having 9 running fine in the office, it’s just that now that even the least expensive ARM boards have moved to armv8, the cost of maintaining a v7 in field will progressively increase, for very little benefit. And at this price they could probably have switched to an RK3399 (to stay in the same range) for a few more dollars, it wouldn’t make a visible difference.
I think in a decade or so it might actually be easier to get some random v7 thing working than it will to get anything v8 going because of all of the extra layers of firmware on v8. :p
