Kaki Pi is a Raspberry Pi-inspired Renesas RZ/V2H AI SBC with four camera connectors, a PCIe 3.0 interface

Japanese company Yuridenki-Shokai Co. Ltd will soon launch the Kaki Pi single board computer based on the just-announced Renesas RZ/V2H Arm microprocessor with a powerful 80 TOPS AI accelerator, with Raspberry Pi-inspired form factor and features such as the 40-pin GPIO header, the same PCIe 3.0 connector as found in the Raspberry Pi 5, and four 22-pin MIPI CSI connectors that look to be compatible with the Raspberry Pi cameras.

The board also comes with up to 8GB LPDDR4,  a microSD card for the OS, a 22-pin MIPI DSI connector for a display, a gigabit Ethernet port, two USB 3.0 ports, two CAN Bus connectors, and other interfaces that make it suitable for robotics applications such as Autonomous Mobile Robots (AMR) and HSR (Human Support Robots) as well as IoT projects.

Yuridenki will provide a Yocto Linux SDK for the Kaki Pi SBC, the company also mentions support for the ROS2 robotic operating system and an unnamed RTOS, and the two AI accelerators in the RZ/V2H microprocessor can help offload OpenCV computer vision workloads.

According to an article on PR Times (Japanese), the Kaki Pi will be launched at the end of April, but I could not find pricing information and whether it will be available outside of Japan at this time. Having said that, I’m confident it will be much cheaper than the Renesas RZ/V2H-EVK evaluation kit that goes for close to $1,200 US. Further information may be found on the official website.

  1. That was quick, not only with RZ/V2H, but “someone else” adopting PCIe 16-pin FFC as a de-facto standard.

    1. If there was a “no key” m.2 socket that would be my favourite…
      Else the miners’ pcie to usb3 stuff looks quite simple, also hdmi cables might do the trick unfortunately sata cables lack one lane.

      Just don’t like the proprietary stuff that locks you into a certain vendors product line

    2. From earlier implemtations like for example the SPI one could imagine that the pcie3 extensions are hardware compatible. It does not help however if there is no driver and the dt-bindings are not updated
      I hope it works, but pi hardware is soo inconvenient on alternative platforms…

    3. This is just terrible news.
      According to specs SoC is capable of 1x4x pcie 3.0 or 2×2. With this pi connector it will have only one of four lanes. 🙁

  2. I may not be a fan of the company making the CPU, but the people designing the board have been paying attention. Look at that DC input!!!! A nice barrel jack and up to 24V input? That’s wonderful! Well done! Let’s see what the price is. Performance wise, it’s Pi3 level in the CPU and GPU.

    The camera I/O and the ML are the real special bits it brings to the table. (things I have no use for and couldn’t care less about) Hopefully someone with experience in that area can talk about their usefulness.
