How to evaluate the 21 inch tablet models

The 21 inch tablet category on our site centers on the H2152T, a wall mount or desktop all-in-one built around the Rockchip RK3288. Page data lists Android 8.1, 2 GB RAM, 16 GB storage, a 1920 x 1080 panel, and optional PoE and NFC. A dash means we don't publish a value for that combo, not that the feature is impossible. Need a different OS build or a higher memory tier? Mention it in the RFQ, and we'll tell you what the current BOM supports.

Choosing between rows isn't about specs. It's about your deployment. The H2152T model page shows the same base data. Need a larger display? Compare with our 24 inch Android tablets. For a smaller counter unit, the 15 inch line may fit better. We'd rather you ask about a blank cell than assume it means no.

What to put in the RFQ for a 21.5 inch Android tablet

When you send an RFQ, specify the model and the Android build you can accept. List any per-order options, too. For this size, tell us if you need PoE, NFC, a camera, or a 3G/4G dongle via USB. GMS or an AOSP build without Google services? Let us know. A custom launcher that locks the device to one app is common for wayfinding and self-service. Say if you need that, and whether ADB must stay open.

Housing color and logo method come next: silk print, metal badge, or boot animation. Will the unit sit on a counter or mount to a wall? Tell us which bracket you plan to use. We can confirm the VESA pattern and any mechanical limits. Don't send payment or network credentials. We only need hardware and firmware details. We answer within 24 hours.

Integration limits and what we do not make

For a 21.5 inch Android tablet, we supply the display, touch panel, mainboard, and housing per the page data. We don't build the kiosk enclosure, the floor stand, or the wall arm. Need a full self-service station? Source those from a metal shop and send us the mounting requirements. Our team can confirm the rear hole pattern and the connector positions.

We also don't preinstall third-party payment apps or certify them. Payment security belongs to the payment application and its certified reader, not to our hardware. If your project needs a specific NFC module, tell us the chip and antenna requirements, and we'll check whether the current BOM supports it. We won't guess. Any value not shown in the table stays unknown until we confirm it against the latest engineering sample.

Common questions

Does the 21.5 inch Android tablet support PoE?

The page data shows a dash for PoE on the H2152T, which means we do not publish a value for that model and option combination. It does not mean no. PoE is listed as optional on many models in this category. Ask us with the model name, and we will confirm whether the current board revision supports IEEE802.3at/af.

Can I get the 21 inch tablet without Google Mobile Services?

Our tablets ship with AOSP Android without Google Mobile Services. If your app depends on Google Play services, tell us in the RFQ so the build can be checked before sampling.

What is the wall mount pattern for the 21.5 inch model?

The page data does not list a VESA pattern, so we cannot state a size from this page. Send the model name in your inquiry, and we will confirm the rear hole spacing and any bracket compatibility. If you already have a mount, include its pattern in the RFQ so we can check fit.
