This summer Banana Pi and ArmSoM launched single-board computers featuring a Rockchip RK3576 processor and plenty of I/O features including support for a PCIe 2.0 SSD, eMMC storage, and a microSD card reader.

Now ArmSoM has introduced a compute module with the same processor. The ArmSoM-CM5 is a Raspberry Pi CM4-sized computer-on-a-module with an RK3576 processor and dual 100-pin connectors that allow you to connect the module to a carrier board. It's available for pre-order for $103 and up and expected to ship in mid-October.

While the ArmSoM-CM5 costs more than a Raspberry Pi Compute Module 4, ArmSoM notes that it has a higher-performance processor, supports up to twice as much storage, and has support for more PCIe and USB connections. The starting price is also for a model with 8GB of RAM and 64GB of storage, and ArmSoM also plans to offer models with up to 16GB of memory in the future.

The RK3576 processor features four 2.2 GHz ARM Cortex-A72 CPU cores, four 1.8 GHz Cortex-A53 cores, Mali-G52 MC3 graphics, and an NPU with up to 6 TOPS of AI performance. It can  also handle 4K video decoding at up to 120 frames per second.

The Raspberry Pi CM5 offers more video output options though.

The board measures 55 x 40mm and features an integrated wireless chip with support for WiFi 6 and Bluetooth 5.3 as well as a socket that can be used for an optional eMMC storage module.

ArmSoM is also offering an optional I/O board for $35 that gives users physical ports and connectors including:

  • 1 x USB Type-C OTG4 x USB 3.0 Type-A
  • 1 x HDMI output
  • 1 x Gigabit Ethernet
  • 2 x MIPI-CSI
  • 1 x MIPI-DSI
  • 1 x microSD card reader
  • 1 x M.2 M-key (PCIe 2.0)
  • 1 x 40-pin header
  • 1 x DC power input

    • The I/O board measures 100 x 80mm and also features fan, maskrom, power, and reset buttons, as well as support for Power over Ethernet.
