Forlinx provides a compatible carrier board that extends the functionality of the FET3506J-S SoM, offering additional connectivity and peripheral interfaces. The OK3506J-S Single Board Computer includes a MIPI DSI interface for display output along with an RGB888 interface supporting resolutions up to 1280×1280@60Hz. It features multiple USB ports, including a USB 2.0 Type-C connector that supports OTG functionality and two high-speed USB 2.0 Type-A ports.

Storage expansion is available through an SDIO interface for an external MicroSD card, though it is only accessible on the SPI NAND version of the SoM. Wireless connectivity is provided via a mini PCIe slot for a 4G module, along with an onboard Wi-Fi and Bluetooth module. The board includes two 10/100 Mbps RMII Ethernet ports for networking, a four-segment audio jack supporting stereo output and MIC input, and an additional onboard microphone.

Industrial communication interfaces include two CAN-FD ports with isolation and protection, as well as an RS485 interface with similar safeguards. Debugging and system expansion are facilitated through a USB-to-serial debug port via a Type-C connector, a JTAG header, and six function keys for system control.
