KDS Software and POS Compatibility

SUNMI FLEX 3 KDS provides Android KDS hardware, not a bundled kitchen software service. Your POS or KDS software provider must confirm the supported application version, Android and Google services requirements, screen layout, network and peripherals. Order routing, ticket timing and reporting depend on the selected software.

Before a multi-location rollout, validate the application on the selected screen and accessory configuration in a pilot kitchen, then confirm the configuration for each station. Share the results and deployment requirements with Rosper to discuss hardware selection.

Frequently Asked Questions

What is restaurant KDS hardware?
Restaurant KDS hardware is the physical touchscreen, mount, power and network equipment used to run kitchen display software. The software receives and organizes orders; the hardware keeps those orders visible and actionable at prep, cook, packing and expo stations. FLEX 3 KDS provides the Android hardware layer. Your KDS or POS software provider determines order routing, ticket timing, bump behavior, reporting and other workflow features.
Is SUNMI FLEX 3 KDS hardware or software?
SUNMI FLEX 3 KDS is commercial Android hardware for restaurant kitchen display deployments. KDS software is selected separately. Before rollout, confirm that the software provider supports the device OS, Google services, screen format, network and required peripherals.
What screen sizes are available for SUNMI FLEX 3 KDS?
SUNMI FLEX 3 KDS is available in 15.6-inch, 18.5-inch and 22-inch Full HD configurations. Rosper SKUs are P11050019, P11050016 and P11050010 respectively.
Is SUNMI FLEX 3 KDS protected for kitchen use?
The front of SUNMI FLEX 3 KDS is rated IP55 for dust and water resistance. SUNMI also states that the aluminum-alloy body was tested under 70°C oil-bath conditions. The specified operating temperature is 0°C to 50°C; 70°C is a test condition, not the operating limit.
Can staff use FLEX 3 KDS with wet hands or gloves?
Yes. SUNMI specifies touch response with wet hands, gloves and oil residue, which helps staff interact with the display during active prep.
Does FLEX 3 KDS support Power over Ethernet?
PoE is available through an optional module. It can combine network connectivity and power in one cable where the deployment and network equipment support it.
Do all FLEX 3 KDS sizes use the same processor?
No. The 15.6-inch Rosper configuration uses a Qualcomm hexa-core processor up to 2.4 GHz. The 18.5-inch and 22-inch Rosper configurations use Qualcomm octa-core processors up to 2.4 GHz. All three listed configurations include 4 GB RAM and 64 GB storage.
Will FLEX 3 KDS run my kitchen display software?
FLEX 3 KDS runs SUNMI OS 4.0 based on Android 13, and the listed Rosper configurations support GMS-EDLA. Exact application, peripheral and version requirements should be validated with the software provider before rollout. Rosper can help arrange hardware validation.
Where can I buy SUNMI FLEX 3 KDS in the U.S. or Canada?
Request a SUNMI FLEX 3 KDS quote from Rosper, an authorized SUNMI distributor serving the U.S. and Canada. Share your software, screen sizes, station count and mounting requirements. Rosper can help narrow the hardware configuration and confirm availability, lead time and project service scope before purchase.
Which SUNMI FLEX 3 KDS screen size should I choose?
Choose SUNMI FLEX 3 KDS based on viewing distance, available station space, mounting clearance and your software interface. The 15.6-inch size suits focused prep or packing stations, 18.5-inch provides a balanced production view, and 22-inch provides a wider order view. Validate your application layout and installation space before selecting a model.
Does SUNMI FLEX 3 KDS include KDS software?
This page is a SUNMI FLEX 3 KDS hardware purchasing entry point. Confirm KDS software, licensing and integration scope separately with Rosper and your software provider. Android support alone does not establish compatibility with a POS or KDS application.
