Raspberry Pi CM4 based PiBox 2 Mini serves as NAS, private Cloud storage (Crowdfunding)

The PiBox 2 Mini is a networked storage solution based on a Raspberry Pi CM4 module and equipped with two slots for 2.5-inch SATA drivers be it HDD’s or SSD’s. It also exposes USB ports and an HDMI port, so I could also be used as a computer. Designed by KubeSail “self hosting company”, the PiBox does not only serve as a standard NAS, but aims to provide a home-based private cloud hosting solution that can replace services such as Google Photos or Dropbox with easily installable templates that are hosted in the box. Pibox 2 Mini specifications: Support SoM – Raspberry Pi CM4 or CM4 Lite with up to 8GB RAM, 32GB eMMC flash Storage 2x SATA port for 2.5-inch drives (SSD or HDD) MicroSD card socket for people using CM4 Lite Video Output – HDMI 2.0 port up to 4Kp60 Display – Built-in 1.3-inch color LCD for information […]

PCIe adapter adds four USB 3.2 ports to Raspberry Pi CM4 IO board

Waveshare has introduced a non-standard PCIe adapter that adds four USB 3.2 ports to the Raspberry Pi Compute Module 4 IO carrier board in a way that does not take too much height. It’s non-standard as it can not be inserted directly into a typical computer PCIe slot, and Waveshare recommends a PCIe extension cable to connect it to a motherboard. Having said that It looks much better on the IO board. Waveshare USB PCIe adapter features: PCIe host interface 4x USB 3.2 Gen1 ports, USB 3.0 / 2.0 / 1.1 compatible Onboard VIA Labs VL805 chip as found on Raspberry Pi 4 SBC Power supply – 12V via PCIe connector or 4-pin header Designed for Raspberry Pi Compute Module 4 IO Board Dimensions – 82×39 mm   Since it’s basically using the same design as Raspberry Pi 4 providing USB ports through the same VL805 PCIe chip, there’s no […]

Turing Pi V2 mini-ITX cluster board takes four Raspberry Pi CM4 or NVIDIA Jetson SoMs

The Turing Pi V2 is a mini-ITX cluster board that builds on the  Turing Pi mini-ITX cluster board taking up to 7 Raspberry Pi Compute Modules introduced in 2019, but instead supports up to four Raspberry Pi CM4 (Compute Modules 4) or NVIDIA Jetson Nano/TX2 NX/Xavier NX SO-DIMM system-on-modules. The Turing Pi 2 board is equipped with two Mini PCIe sockets, two Gigabit Ethernet ports, two SATA III ports, four USB 3.0 ports, a 40-pin GPIO header, and a 24-pin ATX connector for power. Since board-to-board connectors – as found in Raspberry Pi Computer Module 4 – are not ideal for density, the company went with a design including 260-pin SO-DIMM connectors plus CM4 adapter boards, a design that allows them to also integrate other SoMs like the NVIDIA Jetson SO-DIMM modules. Turing Pi V2 specifications: SoM interface – 4x 260-pin SO-DIMM slot for up to four Raspberry Pi CM4 […]

MinCab is the smallest Raspberry Pi CM4 carrier board ever

Carrier boards for Raspberry Pi CM4 modules are all over the place for routers, NAS, industrial gateways, and more. Here’s another one with the Minimal Carrier Board for Raspberry Pi Compute Module 4, or MinCab, that powers the RPi CM4 module via a USB Type-C port. That’s about all it does, although you would also be able to access some GPIOs, 5V,  3.3V, and GND signals via pads on the carrier board. Specifically, eight GPIOs are accessible with IO14, IO15, IO2, IO3, IO4, IO12, IO13, and IO18. Ivan Kuleshov explains this can be useful for Smart Home systems for instance, but it could be anything that requires WiFI and/or Bluetooth connectivity, a powerful Linux capable processor (as opposed to something like ESP32), and a few I/Os. The MinCab might be a good alternative to the upcoming (and delayed) Raspberry Pi 4 Model A for people wanting to use Broadcom BCM2711 […]

Raspberry Pi Compute Module 4 mini router keeps cool with aluminum alloy cover

There are many hardware platforms based on Raspberry Pi CM4 system-on-module, but in most instances, only the baseboard is provided, and you have to handle mounting and/or make an enclosure by yourself. One of those boards was Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4”, which as the name implies, offers two Gigabit Ethernet ports, as well as two USB 3.0 ports, and a micro HDMI port for video output. I say “was” because the company has now designed a PC/ABS case with an aluminum alloy cover acting as a heatsink to keep the RPi CM4 module cool. Raspberry Pi Compute Module 4 mini router’s specifications: SoM – Raspberry Pi CM4 with up to 8GB RAM, 32GB eMMC flash, dual-band WiFi 5 and Bluetooth 5.0 module; replaceable by any Raspberry Pi Compute Module 4 Storage – MicroSD card slot (only accessible with RPi CM4Lite module) […]

CatsPi Industrial Lite RPi CM4 carrier board features GbE, RS485, Watchdog MCU

We’ve seen a fair deal of Raspberry Pi CM4 carrier boards, and here’s another one courtesy of QwaveSystems with CatsPi Industrial Lite board following Raspberry Pi SBC form factor/dimensions, and equipped with Gigabit Ethernet, RS485, USB ports, as well as a watchdog MCU among other interfaces and features. Contrary to what the name implies, CatsPi Industrial Lite only works with Raspberry Pi CM4 with eMMC flash, but not the CM4 Lite module since there’s no MicroSD card on the baseboard. It’s not the first Raspberry Pi Compute Module 4 carrier board with RS485, however, as we previously covered CM Hunter also including CAN and 1-wire interfaces, but QwaveSystems’ solution is more compact and mostly mechanically compatible with Raspberry Pi model B SBC’s. CatsPi Industrial Lite board specifications: Compatible SoMs – Raspberry Pi CM4 with eMMC flash only Video Output – Micro HDMI port Connectivity – Gigabit Ethernet, optional 802.11b/g/n/ac WiFi […]

$30 Raspberry Pi CM4 IoT Router Carrier Board Mini offers Dual Gigabit Ethernet

We’ve recently written about Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4” that offers dual Gigabit Ethernet, and two USB 3.0 ports for software router applications, but it can also be used for IoT, Smart Home, and camera projects, as well as HTPC maker thanks to micro HDMI output and MIPI DSI/CSI connector. It is sold for an affordable $45, exceeding the Raspberry Pi CM4 module. But if all you want to do is get a dual Gigabit Ethernet WiFi router or IoT gateway, DFRobot has now introduced a more compact and cheaper carrier board for Raspberry Pi CM4: “Compute Module 4 IoT Router Carrier Board Mini“. CM4 IoT Router Board Mini specifications: Compatible Module – Raspberry Pi Compute Module 4 / 4 Lite with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB flash, optional 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0 […]
