M70 dual-mode control for commercial LED signage
The Sysolution M70 is designed for mirror displays, advertising screens, light-pole signs and similar commercial installations. Its quad-core Cortex-A17 platform runs Android 7.1 and supports HDMI input/output alongside stored-program playback. A built-in web server and LedOK Express provide content and configuration workflows.
Plan the LED screen within the total 1.3-million-pixel load. The maximum layout dimensions and hardware video-decoding resolution describe different limits. For remote access or synchronized screens, check the selected 4G, GPS, Bluetooth and LoRa hardware instead of assuming every supported feature is included in the base unit.

Frequently asked questions
What is the difference between M70 synchronous and asynchronous playback?
The M70 supports a synchronous HDMI source and asynchronous stored-program playback. The same sending box supports both modes, with HDMI input/output and local or remote program-management functions.
Can M70 drive a full 1920 × 1080 LED display?
The stated LED load is 1.3 million pixels. Its asynchronous maximum width of 1920 and maximum height of 1080 are separate limits within that load, not a full 1920 × 1080 LED canvas. The PDF’s higher decoding-resolution entry also does not increase the LED output capacity.
Are 4G, GPS and Bluetooth supplied as standard?
The technical table labels the 4G module, external GPS and Bluetooth 4.0 as optional. Confirm the chosen configuration. Onboard Wi-Fi supports AP and Station modes, and Ethernet is also listed.
Can the M70 synchronize programs across several screens?
The M70 supports a LoRa modem for wireless program synchronization. Check that the required modem and configuration are provided for the multi-screen installation.
Which power supply and software does the M70 use?
The listed power input is 5 VDC, 3 A. LedOK Express is specified for the controller, and the built-in web server supports local program editing from computers and mobile devices.
