Against the backdrop of the ever-increasing demand for efficient development platforms in the field of intelligent industrial applications, the Rockchip RK3506 series of chips have become a popular choice for scenarios such as industrial control, the Internet of Things (IoT), and edge computing, thanks to their high performance, low power consumption, and rich interfaces. Forlinx Embedded has keenly captured the market demand and launched the OK3506-S12 Mini development board, a powerful development tool designed specifically for high cost-performance.

First Unboxing Experience: Simple yet Sophisticated

The packaging of Forlinx Embedded's OK3506-S12 Mini development board uses a hard-paper box. The surface is printed with the product model, contact information, and Forlinx Embedded's brand logo. The overall design is simple and elegant. After opening the package, the development board and its accessories are fixed inside with a custom-made mold to ensure they are not damaged during transportation.

Inside the box, there are the main body of the development board, a Type-A to Type-C adapter cable, an accessory package, and a factory certificate.

Next, let's take a look at the appearance details.

The OK3506-S12 Mini development board is very compact, measuring only 65mm x 105mm. It feels about the same size as the antique iPhone 4 in the author's drawer.

Despite its compact size, it integrates a rich variety of interfaces, including a Raspberry Pi 40-Pin GPIO interface, two native CAN-FD interfaces, RMII, UART, Display, and other interfaces, meeting the diverse development needs of engineers.

Hardware Configuration
