Seaberry Mini-ITX carrier board for Raspberry Pi CM4 exposes 11 PCIe slots and sockets

SeaBerry mini-ITX motherboard Raspberry Pi CM4

The Raspberry Pi CM4 may only have a one PCIe x1 Gen 2 interface, but this has not stopped ALFTEL from designing Seaberry, a mini-ITX carrier board for the Raspberry Pi Compute Module 4 with eleven slots and sockets making use of the single 5 Gbps PCIe Gen 2 interface. The board also offers two SATA ports, one Gigabit Ethernet port, one RJ45 console port, two HDMI ports, a micro SD card slot, two USB 2.0 ports, as well as the usual 40-pin GPIO expansion header, besides the PCIe x16 slot, a PCIe x1 side slot, and M.2 and mPCIe sockets. Seaberry carrier board specifications: Compatible systems-on-module Raspberry Pi CM4 module (Regular or Lite) Radxa CM3 Pine64 SoQuartz Storage – 1x MicroSD card for Raspberry Pi CM4 Lite, 1x M.2 socket for NVMe SSD (See PCIe expansion section) Video Output – 2x HDMI output ports, 1x MIPI DSI connector Camera […]

10.1-inch Raspberry Pi All-in-One touchscreen display review – Part 1: Unboxing and installation

Raspberry Pi OS All-in-One Touchscreen Display

I’ve just received a 10.1-inch touchscreen display designed for Raspberry Pi model B boards with 1200×800 resolution from the EVICIV store on Amazon that also offers models with 1366×378 and 1920×1200 resolutions, and allows users to create an All-in-One computer based on the popular SBC. The product can also be used as a standalone display connected to an HDMI or USB-C (via DisplayPort Alt mode) source, so it could be interesting for all sorts of projects and not only ones relying on Raspberry Pi boards. In the first part of the review, I’ll check out the hardware, install a Raspberry Pi 4, and boot it to check out whether it works, before going into more details in the second part of the review. RPI All-in-One Touchscreen Display Unboxing The package lists some of the specs and highlights features of the device with a built-in stereo speaker, support for older and […]

Meet Dot – A stamp sized 2-wheel robot powered by a Raspberry Pi RP2040 board

Kaisar (aka Roboticbits) has developed a tiny robot based on Pironomi Tiny 2040 Raspberry Pi RP2040 development board, which he/she claims is the smallest in the world, but it might not be depending on how one measures it. Nevertheless, the Dot is a cool project with two wheels with a 3V DC motor attached to the 22.9 x 18.2 mm board, and a 70mA battery to power the mini robot. Here’s what it looks like in action. Introducing Dot.. a stamp size @Raspberry_Pi #RP2040 robot.. the smallest in the world! Makes a proper use of the @pimoroni #Tiny2040!#raspberrypi #robot #robotics #make pic.twitter.com/rnYghWY6NJ — kaisar (@roboticbits) November 11, 2021 Eventually, the robot should be documented on Github, but at this time we have limited information with a photo accompanying the video demo above. Tom’s Hardware got more details about the software as well, with Kaisar saying the firmware was developed with […]

Only 3 days left to get a Raspberry Pi RP2040 + ESP32 board at 80% discount (Sponsored)

There’s always a bunch of DIY electronics on Kickstarter, but right now nothing is as compelling as UDOO KEY. Built by UDOO, a multidisciplinary team that has already completed (and delivered) four highly successful Kickstarter projects, UDOO KEY is an innovative, never-before-seen combination of Raspberry Pi RP2040 and ESP32. Mind you: unlike the newest microcontroller by Arduino, UDOO KEY doesn’t simply use the ESP32 for connectivity. Instead, it features a fully programmable ESP32, offering the widest set of options in the field when it comes to Edge AI. Predictive maintenance, sound recognition, keyword recognition, gesture recognition, face recognition, object detection & classification… these are just a few of the many applications you can build, also thanks to the several programming languages and libraries supported, such as Micropython, C, C++, TensorFlow Lite and TinyML. This is not some fancy mini PC for low-budget gaming, but a platform for AI at the […]

Android 12 on Raspberry Pi 4 – (Almost) everything works

Android 12 (AOSP) source code was released last month, and a developer took the opportunity to port Android 12 to the Raspberry Pi 4 single board computer and derivatives. More specifically, KonstaT created an unofficial build of LineageOS 19.0 for Raspberry Pi 4, Raspberry Pi 400 keyboard PC, and Compute Module 4 working on systems with at least 2GB of RAM. While it’s reserved for advanced users, the Android 12 build appears to work pretty well with most features supported including: Video HDMI display including CEC Touchscreen/multi-touch (USB touchscreens, Waveshare SPI touchscreens) Hardware-accelerated graphics (V3D, OpenGL & Vulkan) Audio HDMI, 3.5mm jack, USB microphones, Bluetooth speakers/headphones Audio DACs such as Hifiberry DAC+ Connectivity Ethernet WiFi including tethering Bluetooth including Bluetooth tethering GPS using external USB modules USB tested with USB mouse, keyboard, storage, etc… USB-C: ADB, MTP, PTP, USB tethering I/Os (GPIO, I2C, SPI) tested with Remote controls via external […]

Giveaway Week 2021 winners announced!

Giveaway Week 2021 is now over, and I’m ready to announce the winners. This year, CNX Software was joined by Rakwireless and Shenzhen Xunlong Software, as I did not have enough hardware to send out. I also had planned to give away Crowbits Master Kit, but when I realized the ESP32 module had a battery, I would have had to ask $100 just for shipping, plus having the risk of messing things up, since I’ve never sent devices with batteries with the new regulations. Nevertheless, the void was filled thanks to the generosity of Rakwireless who offered a solar-powered LoRa GPS tracker, and Shenzhen Xunlong Software who proposed an Orange Pi R1 SBC with a plastic enclosure. Let’s go through the list of winners located in four continents with Europe, North America, Asia, and Oceania represented: NanoPi R2S gateway – Jason, CANADA WisBlock Kit 2 LoRa-based GPS Tracker with Solar […]
