- The Raspberry Pi Compute Module 4 eschews a built-in USB 3.0 controller and exposes a 1x PCI Express lane. The slightly older Raspberry Pi 4 model B could be hacked to get access to the PCIe lane (sacrificing the VL805 USB 3.0 controller chip in the process), but it was a bit of a delicate operation and only a few daring souls tried it.
Four-slot Raspberry Pi cluster board starts at $80
Mar 4, 2020 — by Eric Brown — 65572 viewsIPTerra’s “CloverPi” cluster board starts at $80 on Kickstarter, supporting up to 4x Raspberry Pi SBCs with power, switches, LEDs, and network headers for each plus a 5-port GbE switch with uplink port.
Most Raspberry Pi cluster kits we’ve seen support the Raspberry Pi Compute Module, such as Turing Pi’s $128, 7-board Turing Pi Clusterboard or MiniNodes’ $259 5 Node Raspberry Pi 3 CoM Carrier Board. There’s also Pimoroni’s, 4-board, $49 RPi Cluster HAT v2.3, which instead supports the Raspberry Pi Zero. Like BitScope’s Blade boards, IPTerra’s new CloverPi can cluster regular-sized Raspberry Pi boards.

Houston-based startup IPTerra is a fifth of the way to its $15,000 all-or-nothing Kickstarter goal for the CloverPi, starting at $80 or $90 early bird prices through April 30, with shipments due in June or August, respectively. This is actually the CloverPi 1.4 — the first version IPTerra has sent to production — and if this doesn’t work, it’s already worked on a CloverPi 2.0 model.
The CloverPi, which we saw on Geeky Gadgets, consists of a backplane for connectors that house up to four Raspberry Pi SBCs, including any model with a 40-pin connector. There’s also a board that fits in the fifth slot with a 12 or 19V power supply that supports all four SBCs and a 5-port Gigabit Ethernet switch, with one of the ports used for uplink.

Each Pi board has its own dedicated power switch, network header, networking link light, and individually addressable LED. Mounting holes are also included. Applications are said to include K8s, Docker swarms, OpenStack development, and small office server or Open Flickr stacks.

The CloverPi is available on Kickstarter in $80 or $90 early bird prices through April 30, with shipments due in June or August, respectively. These will be followed by a $120 package due in November and an eventual $150 retail price. Double-board discounts are also available. More information may be found on the CloverPi Kickstarter page and the IPTerra website.

Raspberry Pi enthusiasts interested in learning more about using the new Raspberry Pi Compute module with external graphics cards may be interested in a new video created by Raspberry Pi aficionado Jeff Geerling, who explains a little more about his experimentation below. A couple of graphics cards used in the project include the Zotac Nvidia GeForce GT 710 and VisionTek AMD Radeon 5450.
“After I learned the Raspberry Pi Compute Module 4 IO Board comes with a PCIe slot, I know the first thing I thought about testing was a graphics card. The Mali GPU inside the Pi 4 is decent on its own, but what if you could use external video cards, for mining, for rendering, or for CUDA or other GPU-accelerated computing purposes?”
Specifications of the new Raspberry Pi Compute Module 4
– 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU
– VideoCore VI graphics, supporting OpenGL ES 3.x
– 4Kp60 hardware decode of H.265 (HEVC) video
– 1080p60 hardware decode, and 1080p30 hardware encode of H.264 (AVC) video
– Dual HDMI interfaces, at resolutions up to 4K
– Single-lane PCI Express 2.0 interface
– Dual MIPI DSI display, and dual MIPI CSI-2 camera interfaces
– 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM
– Optional 8GB, 16GB or 32GB eMMC Flash storage
– Optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0
– Gigabit Ethernet PHY with IEEE 1588 support
– 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI
