Engineering verification

The supplied RJY3566M datasheet is the primary reference; the earlier website image uses RJY-RK3566M. Its core summary lists 2/4 GB RAM and 16/32/64 GB eMMC, while its hardware table lists 1/2/4/8 GB and 8/16/32/64/128 GB. MicroSD is stated as 2 TB in the summary and 512 GB in the table; confirm the supported limit. The touch connector is labelled both 1.0 mm and 0.5 mm pitch. The GPU and decoder table contains apparent GS2 and H.256 typos. Connector notes retain these discrepancies. No revision number or issue date is printed in the supplied 11-page PDF.

Designed for integration

Product overview.

One platform for Linux and Android projects

RJY3566M combines a quad-core Cortex-A55 processor with Mali-G52 2EE graphics and an NPU specified at up to 1.0 TOPS. The supplied datasheet lists Ubuntu 20.04, Debian 11, Android 11 and Buildroot, giving system developers several software starting points.

Connect displays and peripherals at board level

Choose Micro HDMI, eDP or MIPI DSI for display output. Separate MIPI CSI and I²C touch connectors support camera and touch integration. A 40-pin 1.27 mm GPIO header and a 39-pin high-speed expansion interface expose additional system connections; Ethernet and USB 3.0 are described as expansion signals.

Plan the mechanical and power arrangement

The board measures 70 × 45 × 9.6 mm. The documented power inputs are USB Type-C at 5 V / 3 A and a 2-pin GH1.25 connector at 12 V / 2 A. Use the supplied interface diagrams, mechanical drawing and connector tables to check cable orientation and enclosure fit.

Work from the supplied technical document

The original 11-page Chinese datasheet is available in Technical resources. The English tables below translate its technical content and identify conflicting values or incomplete definitions. Request a confirmed board configuration and revision-matched development package before finalizing integration.

Key features

  • RK3566 quad-core Cortex-A55 up to 1.8 GHz, Mali-G52 2EE graphics and up to 1.0 TOPS NPU.
  • Linux options include Ubuntu 20.04 and Debian 11, alongside Android 11 and Buildroot.
  • Micro HDMI, eDP and MIPI DSI outputs, plus camera and I²C touch connections.
  • 40-pin 1.27 mm GPIO and 39-pin high-speed expansion for system integration.
  • Compact 70 × 45 × 9.6 mm format, with −20 to +70 °C operating range.

Before you integrate

Product questions.

Which operating systems are listed in the datasheet?

Ubuntu 20.04, Debian 11, Android 11 and Buildroot are listed. The document states that an SDK is provided; request the package matched to the board revision and target system.

Which memory and storage capacities should I specify?

The core summary lists 2/4 GB LPDDR4x and 16/32/64 GB eMMC 5.1. Its hardware table gives wider ranges. Confirm the installed capacity and supported configuration rather than treating all combinations as separate verified models.

What is the MicroSD capacity limit?

The PDF summary says up to 2 TB, while the hardware table says up to 512 GB and supports system boot. This conflict needs confirmation for the selected card, OS and board revision.

Is there a Gigabit Ethernet socket on the board?

The datasheet lists 100/1000 Ethernet on the 39-pin expansion interface. A carrier or adapter implementation and its pin definitions need confirmation; do not assume an onboard RJ45 socket.

Can I connect any 6-pin touch panel?

No. Confirm I²C wiring, 3.3 V electrical compatibility, pin orientation and the connector. Section 5.3 gives conflicting 1.0 mm and 0.5 mm pitch labels.

Where are the pin definitions and development files?

Connector pin tables are transcribed in the Connectors & pinout tab, and the original 11-page Chinese PDF is available under Technical resources. SDK, BSP and firmware packages have not been uploaded.
