Raspberry Pi Compute Module 4 industrial carrier board supports M.2 NVMe SSD, 4G LTE modem

Since the Raspberry Pi Compute Module 4 launch last fall, we’ve seen several interesting carrier boards for the system-on-module including Wiretrustee to build a NAS with up to four SATA drives, the compact, Arduino-sized Piunora board that also include an M.2 socket, or Over:Board mini-ITX carrier board. Oratek brings another one specially designed for industrial use cases with TOFU Raspberry Pi Compute Module 4 carrier board offering wide DC input, Gigabit Ethernet with PoE, M.2 NVMe SSD or 4G LTE modem support, among many other features. Specifications: Raspberry Pi Compute Module 4 socket Storage NVMe SSD via M.2 2242 Key B socket (See Expansion section) MicroSD card slot Video Output HDMI 2.0 port up to 4Kp60 MIPI DSI connector for Raspberry Pi LCD display Camera – 1x MIPI CSI connector for Raspberry Pi camera Connectivity Gigabit Ethernet port with PoE Optional WiFI 5 and Bluetooth 5.0 on Raspberry Pi CM4 module Optional 3G/4G LTE (USB) modem via M.2 2242 Key […]

StereoPi v2 stereoscopic camera is powered by Raspberry Pi CM4 (Crowdfunding)

StereoPi stereoscopic camera based on Raspberry Pi Compute Module 3 was introduced in late 2019 on Crowd Supply.  The camera can record 3D video, create 3D depth maps with OpenCV, and benefits from the Raspberry Pi software ecosystem. The developers are now back with an upgraded model. StereoPi v2 comes with many of the same features, but as it is based on Raspberry Pi CM4 (Compute Module 4) it offers better performance, Gigabit Ethernet, Wifi & Bluetooth connectivity out of the box, while other features like PoE, TFT screen, shot button, etc.. are optional. StereoPi v2 specifications: Supported SoM – Raspberry Pi CM4 or CM4Lite modules Storage – MicroSD card socket Video Output – Micro HDMI port Camera I/F – 2x MIPI CSI camera connector plus “hackable camera lines” Networking – Gigabit Ethernet RJ45 port, plus optional WiFi 5 and Bluetooth 5.0 on Raspberry Pi CM4 module USB – 2x USB 2.0 Type-A ports, 1x USB 2.0 interface on header […]

iPod Classic given new life with Raspberry Pi Zero W & Spotify

Guy Dupont got a bunch of 2004, fourth-generation iPod Classic MP3 players from his mother-in-law, and instead of playing MP3 files on the media players, he decided to repurpose one with a Raspberry Pi Zero W to be able to stream music from Spotify over WiFi. The resulting project is called sPot (ess-pot), and looks just like an original iPod, but it’s a Linux device that can stream/search via Spotify with a UI written in Python and based on the original iPod experience. But apart from the enclosure, and the original “click wheel” there’s not much left from the original design. Besides the Raspberry Pi Zero W SBC and iPod enclosure, the sPod includesAdafruit Mini LiPoly/LiIon USB Charger and PowerBoost 1000 Basic boards for charging and power management,  a 1,000mah,3.7V rechargeable li-ion battery, vibration motor discs For haptic feedback, a 2-inch Adafruit TFT display, and a few other components, wires, and cables which you can find the project’s page on […]

Lisperati1000 Lisp portable programming workstation features Raspberry Pi Zero W, ultra-wide display

Conrad Barski (Lisperati) wanted a portable “workstation” to write in Lisp and see all those parentheses. Since there aren’t many devices with an ultra-wide display, he decided to build his own “Lisperati1000” ultra-compact Lisp programming workstation powered by a Raspberry Pi Zero W, and equipped with an ultra-wide 1920×480 8.8-inch display, a compact keyboard made of Cherry Brown switches, and a 4,400mAh dual battery all housed in a 3D printed enclosure. When Conrad first showcased his little handheld computer on Twitter, he first claimed only 3 will ever be built, but think quickly got out of control with the project being featured on Hacker News, and he changed his mind after seeing the popularity of the DIY computer. UPDATE: Due to high demand, I have decided to fund a project to release this as a kit. If you are an electrical engineer and/or know about machining Aluminum, please get in touch! — Conrad Barski (@lisperati) February 4, 2021 The launch […]

Build a Raspberry Pi CM4 4-Bay NAS with Wiretrustee Carrier board

Broadcom BCM2711 processor comes with a PCIe interface that is used for the USB ports on the Raspberry Pi 4 SBC, but that is exposed through the board-to-board connectors of Raspberry Pi Compute Module 4, aka Raspberry Pi CM4, and allows all sort of designs. So far we’ve mostly seen this PCIe interface used for M.2 expansion slots on devices ranging from industrial computers to carrier board such as Piunora or Gumstix Raspberry Pi CM4 development board. But Wiretrustee had a different idea and designed carrier board with Marvell 88SE9215 PCIe to SATA controller and offering four SATA connectors to build a 4-bay NAS with Raspberry Pi CM4 module. Wiretrustee carrier board specifications: Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite Storage 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) chip tested at a write speed of ~220MB/s on each of the SATA ports (not simultaneously) MicroSD card […]
