Antmicro ARVSOM offers StarFive JH71x0 RISC-V processor, Raspberry Pi CM4 compatibility

The Linux capable BeagleV SBC, now called “BeagleV Starlight”, was announced last January with a StarFive JH7100/JH7110 64-bit RISC-V processor, and developers and beta users have just started to get their hand on the board in recent days.

But there’s another StarFive JH71x0 hardware in the works with Antmicro ARVSOM. The system-in-module will feature the dual-core RISC-V processor, and be compatible with Raspberry Pi CM4, and by extension Antmicro’s Scalenode server-oriented baseboard.

Antmicro AVRSOM RISC-V CPU Module

The company did not provide the complete specifications for the module, but based on public information available, Antmicro ARVSOM should feature the following:

  • SoC – StarFive JH7100 Vision SoC:
    • RISC-V U74 dual-core with 2MB L2 cache @ 1.5 GHz
    • Vision DSP Tensilica-VP6 for computing vision
    • NVDLA Engine 1 core (configuration 2048 MACs @ 800MHz  – 3.5 TOPS)
    • Neural Network Engine (1024MACs @ 500MHz – 1 TOPS)
    • VPU – H.264/H.265 decoder up to 4Kp60, dual-stream decoding up to 2Kp30
    • JPEG encoder/decoder
    • Audio Processing DSP and sub-system
  • System Memory – Up to 8GB LPDDR4
  • Storage – TBD
  • 2x 100-pin board-to-board connectors with a pinout (at least partially) compatible with Raspberry Pi CM4
  • Supply Voltage – 5V
  • Dimensions – 55 x 40 x 4.7mm with 4x M2.5 mounting holes

Note we were just informed that BeagleV and ARVSOM will first ship with the JH7100 dual-core RISC-V processor, it will eventually be upgraded to JH7110 quad-core U74 RISC-V processor with Imagination Tech IMG BXE-4-32 GPU, and PCIe support.

Antmicro Scalenode Raspberry Pi CM4The RISC-V CPU module will be compatible with Scalenode baseboard, shown with a Raspberry Pi Compute Module 4 above, with Gigabit Ethernet and PoE, several expansion connectors in a server-oriented form factor, as well as an M.2 key M PCIe connector for SSD storage or add-on boards such as AI accelerators like Google Coral accelerator.

Up to 18 Scalenode boards can be installed in a 1U rack to build continuous integration systems, or custom, open-source hardware & software-based systems for edge AI applications. ARVSOM should also be compatible with any other Raspberry Pi CM4 baseboard, especially once the JH7110 model comes out with PCIe and graphics acceleration.

Further information can be found in the announcements for the module and the baseboard.

And so RISC-V begins! Cool.


  • great there will be a RISC-V Compute Module. And kudo’s to the Raspi organization for defining and providing that standard
  • I see no prices. But seeing the server oriented Scalenode baseboard, I fear this will be an expensive combination
  • we need cheap RISC-V solutions! So sub-100USD, including shipping and VAT. Just like the Raspi and other ARM based SBC’s

Just my 3 cents.

Assuming that this board exposes same interfaces as BeagleV, (including both CSI-2 interfaces, which could be tricky) through this module there could be the easiest way to make more complex robots and computer vision systems.

Both BeagleV and ARVSOM looks great for early adopters of RISC-V. With deployment of those I would certainly be more cautious as the StarFire is privately held solely China company and for security domain in EU/US this is a no go. So evaluation and development fine, deployment no.

Combined with NVIDIA’s patents (read the license) and Imagination Tech’s commitment to open source (sarcasm), can someone explain what the point of using RISCV was?

that’s a gorgeous form factor and spotting a colossally huge, flat, & dominating Coilcraft transformer. I hope imagination tech & antmicro can give the linux drivers on this gpu a decent treatment. ditto on the dsp & vision chips.

again curious what exactly the high density ports are that appear on both sides of the module. talk of
m.2 but not visible or not really what’s happening. I’d love to see higher density connectors make big inroads.
