H713M-CY-4D308 Projector Mainboard

1.This H713M‑CY‑4D308 mainboard uses separate RAM and EMMC chips. What practical differences does it have compared with the EMCP‑version projector mainboard?

This model adopts discrete 1G DDR3 RAM chip and independent 8G EMMC storage, while the EMCP version integrates RAM and storage inside one single chip. Both deliver comparable overall performance. The discrete‑chip solution offers more flexibility for component replacement yet sets higher requirements for PCB layout; the EMCP variant features simpler board wiring. They share identical LVDS output, Wi‑Fi/BT specification and Android 11 system. It outputs native 720P resolution only, differing from the EMCP model merely in storage hardware packaging.

2.Equipped with Mali‑G31 GPU, what capabilities does this mainboard bring for video decoding and projector display? Can it decode 1080P video sources?

The Mali‑G31 GPU handles graphic rendering and UI output. The SoC supports H.264 and H.265 1080P video decoding for media playback. Nevertheless, its LVDS hardware output remains 1280*720 (720P). 1080P video content will be scaled down for 720P optical engine and native 1080P display output is not supported.

3.Does this mainboard support HDMI‑IN input? What are the specifications of its display interface and which optical engines are compatible?

It supports HDMI‑IN for external signal input from laptops, OTT boxes and other sources, alongside USB‑OTG and earphone jack. Its 30PIN 8‑bit LVDS display interface delivers native 1280*720 output. It only works with 720P LVDS optical engines and cannot drive 1080P panels directly. Please double‑check the pin definition of your optical engine before ordering.

4.Does H713M‑CY‑4D308 support OEM software customization, such as boot logo modification and pre‑installed APK applications?

Powered by Android 11 OS, this mainboard supports OEM customization including custom boot logo, pre‑install or remove APKs and UI adjustment. Custom software services are subject to specific MOQ requirements. Local USB firmware update is available, and OTA remote upgrade can be enabled for bulk‑order projects upon evaluation.

5.What are the MOQ and sample policy for this projector mainboard? Can I get datasheets and relevant technical documents?

The MOQ for standalone mainboard supply is 1000 pieces. Samples are accessible; sample cost and freight shall be covered by buyers, and sample fees can be deducted from subsequent bulk orders. Datasheet is provided upon request. Schematic diagrams and low‑level firmware resources will be handed over after bulk‑order confirmation.
