Mekotronics D58 embedded computer features 6 HDMI outputs for video walls or mirrored displays

Mekotronics D58 is a Rockchip RK3588 embedded computer running Android or Linux with six HDMI outputs for 4K video walls or multiple mirrored displays that should be mostly useful for digital signage applications.

The system comes with up to 16GB RAM and 128GB eMMC flash, supports NVMe and SATA storage, comes with two GbE ports, WiFi 6 connectivity, optional 4G LTE and GNSS, one 4K-capable HDMI input port, four USB ports, some DB9 connectors for serial communication (RS232, RS485, TTL), and a terminal block with GPIOs and CAN bus.

Mekotronics D58 specifications:

  • Terminal block for 4x GPIOs and CAN Bus
• Misc – Infrared receiver
• Power Supply – 12V/2A via 5.5×2.0mm DC jack
• Dimensions – TBD

It’s unclear how the video wall function is implemented and I’m unable to find chips designed for this purpose, so it might be done through an FPGA (TBC). There are several video wall controllers capable of driving six screens or more on the market including on Amazon and Aliexpress with prices ranging from $40 to over $1,000 depending on the functions, but those connect to a host computer, while the Mekotronics D58 is an all-in-one system that serves both as an Android or Linux host and video wall controller. The company shot a video demo in Android.

The company did not provide availability and pricing information for the Mekotronics D58 embedded computer. More details may be found on the product page.
