Toybrick TB-RK3588SD: A Rockchip RK3588S-Based SBC in Raspberry Pi Form Factor

The Toybrick TB-RK3588SD is a single-board computer(SBC) powered by the Rockchip RK3588S, equipped with 8GB LPDDR4X RAM and a dual-core GPU and NPU for AI. It’s designed for multimedia applications in AI, VR, and cloud computing, all while maintaining a similar form factor to a Raspberry Pi.

In our previous post, we covered similar Rockchip RK3588 SBCs like the Youteetoo Cyboboard R1, Broadcon Idea3588S, Indiedroid Nova SBC, Orange Pi 5 and many others feel free to check those out if you are looking for similar SBCs.

The RK3588S SoC combines quad-core Cortex-A76 (up to 2.4GHz) and Cortex-A55 (up to 1.8GHz) CPUs, an ARM Mali-G610 MP4 GPU (up to 1GHz), and a 6-TOPS NPU. This configuration supports advanced graphics with OpenGL ES3.2, OpenCL 2.2, Vulkan 1.1, and high-performance 2D/3D acceleration. It also features video decoding up to 8K@60fps, encoding up to 8K@30fps, and is compatible with various AI frameworks, making it ideal for AI and multimedia applications.

The Toybrick TB-RK3588SD offers multiple video interfaces, including MIPI-DSI, HDMI, and DisplayPort via USB Type-C, supporting 8K@60fps decoding (H.265/VP9) and 8K@30fps encoding (H.265/H.264). Designed for applications in AI, cloud and edge computing, VR/AR, and gaming, further details are available on the Toybrick Wiki.

The Toybrick TB-RK3588SD is available in three packages: Basic Kit (board only), 20W PD PSU Kit (board + 20W PD power), and Development Kit (board, 20W PD power, 32GB MicroSD, MicroSD reader). The powerboard features include three buttons, LEDs, USB to serial, a six-axis sensor (three-axis accelerometer and gyroscope), power management, 2.5GHz/5.0GHz antennas, a 5V fan connector, and an SPI interface for TFT screens.
