IP68-rated Rockchip RK3588 embedded mini PC works underwater

Mekotronics R58X-IP68 is a Rockchip RK3588-powered embedded mini PC with an IP68 ingress protection rating that makes it waterproof and even allows it to run submerged underwater.

We’ve previously covered IP68 or IP67-rated hardware platforms like IoT gateways, thermal cameras, telemetry modules, and more. Those often rely on M12 or M8 connectors for waterproofness, but the Mekotronics R58X-IP68 relies on regular connectors housed in a waterproof socket and cable.Mekotronics R58X-IP68

E-Weichat waterproof connectors closed

The video below shows the Mekotronics R58X-IP68 operating underwater playing a video with all ports connected to waterproof cables.

The waterproof sockets and cables are provided by a Chinese company called E-Weichat which happens to have a shop on AliExpress. Those waterproof sockets and cables are relatively inexpensive (around $8 to $10) for the HDMI socket and 1-meter cable or the USB socket and 60-cm cable.

Mekotronics told CNX Software the R58X-IP58 is available now with a sample price of $240 US in 4GB/32GB configuration and all waterproof connectors and cables. A few more details can be found on the product page.

[ Does a Wifi or BT range change with transmitters/receivers from under water? ]

[ thx, me also wondering, if wireless (Wifi frequency ranges, BT, BLE, ZigBee, 6LoWPan, being on frequencies ~430/860/920MHz, 2.4GHz, 5.xGHz, 6GHz, 60GHz) is influenced from high moisture/cloudy/rainy/snowy weather conditions or even dust or smoke? How about high temperatures in summer? ]
