OK153-S: New Linux Single-Board Computer with ARM and RISC-V

Key Takeaways

1. The OK153-S is a single-board computer that uses the FET153-S SOM, similar in use to a Raspberry Pi.
2. It features the Allwinner T153 SoC, combining four ARM Cortex-A7 cores and a RISC-V E907 chip for high-performance data processing.
3. Memory options include 256 MB, 512 MB, or 1 GB of DDR3 RAM, with storage options up to 8 GB in NAND or eMMC.
4. It supports Linux 5.10 and is designed for industrial applications, lacking an HDMI port but offering various connectivity options.
5. Key ports include two USB 2.0, one USB-A, one Ethernet, two RS485, and two CAN-FD, along with slots for nano-SIM and microSD.


The OK153-S is an innovative single-board computer that utilizes the FET153-S SOM. The FET153-S is effectively mounted on a carrier board, making it similar in use to a Raspberry Pi, as the connectivity is structured in a largely standard way. The system on chip (SoC) featured is the Allwinner T153, which integrates a computing chip that combines two distinct architectures: it has four ARM Cortex-A7 cores and a RISC-V E907 chip. Forlinx claims that this combination renders the OK153-S ideal for intensive data processing and applications demanding high real-time performance.

Memory and Storage Options

Depending on which model you choose, the OK153-S comes equipped with either 256 MB, 512 MB, or 1 GB of DDR3 RAM. Additionally, it has options for 256 MB or 512 MB of NAND storage or eMMC storage that reaches up to 8 GB in capacity. It supports Linux 5.10, a system many developers are likely to recognize and be comfortable with.

Connectivity Features

If you’re looking for an HDMI port on the OK153-S, you’ll be disappointed, but that’s not unexpected for a device primarily aimed at industrial applications. Instead, it features MIPI CSI, and displays can be attached using MIPI DSI. The array of ports includes two USB 2.0 ports, one USB-A port, one Ethernet port, two RS485 ports, two CAN-FD ports, and plenty more. There are also slots available for a nano-SIM and a microSD memory card.

Details regarding pricing or when it will be available are still unknown.
