The Turing Pi V2
October 08, 2021

Turing Pi have announced further details of their second Mini-ITX sized Compute Module cluster board.

Compute modules are effectively tiny low power consumption computers. A module has a processor and memory, often flash storage and sometimes Wi-Fi, and not much else. Compute Modules lack connectivity, so are generally mounted on a carrier or IO board to provide a route to the outside world.

The Turing Pi V2 is a carrier board which connects and powers up to 4 Raspberry Pi CM4 or Nvidia Jetson compute modules together.

The board becomes a cluster when multiple modules are fitted, with each compute module functioning as a node within that cluster.

The clever stuff happens underneath.

2x Gigabit LAN ports sit on the back panel, with an internal 7-port switch with VLAN support connecting all the modules together.

A Baseboard Management Controller allows remote board diagnostics and cluster management. The BMC and its network run independently from the data plane.

External storage is supported with 2 SATA 6Gbps interfaces. There are plenty of other interfaces to connect between the modules: HDMI, 2x Mini PCIe, 2x SATA, 4x USB 3.0, 3x 40-pin GPIO, Audio etc.

With 4x Raspberry Pi CM4 pi4.8_x modules connected, a cluster would have 16 cores and 32GB of memory on tap.

The Turing Pi V2 has a standard 24-pin ATX power connector and 17x17cm Mini-ITX form factor, meaning almost all Mini-ITX cases and power supplies can be used to house the cluster.
