BeepBerry handheld Linux computer drives 2.7-inch display with Raspberry Pi Zero W

BeepBerry

Good news! The PocketCHIP handheld Linux computer is back! OK, not quite but that’s what the Raspberry Pi Zero-powered BeepBerry reminds me of with a Blackberry-like keyboard, a small 2.7-inch display, and a 2,000mAh LiPo battery for power. The BeepBerry is another open-source hardware design from SQFMI, who previously did the Watchy ESP32 E-Ink smartwatch, that runs Raspberry Pi OS Lite on the Raspberry Pi Zero/Zero W, and also includes a Raspberry Pi RP2040 to handle the keyboard and peripherals. BeepBerry specifications: SBC – Raspberry Pi Zero board with a Broadcom BCM2835 ARM11 processor @ 700 MHz, VideoCore IV GPU, or Raspberry Pi Zero W with WiFi and Bluetooth Storage – MicroSD card slot Display – Ultra-low power high contrast 2.7-inch Sharp Memory LCD with 400 x 200 resolution User input – QWERTY tactile keyboard w/ backlight and touchpad based on Solder Party BB Q20 Keyboard USB – USB-C programming […]

EDATEC ED-IPC2010 – A compact DIN Rail mountable industrial computer based on Raspberry Pi CM4

DIN Rail Raspberry Pi CM4 industrial computer

EDATEC has launched yet another Raspberry Pi CM4-powered industrial computer with the ED-IPC2010 offering a more compact design than the company’s CM4 Industrial and CM4 Sensing models, and an aluminum alloy enclosure that can easily be mounted to a DIN Rail. Most of the specifications of the new ED-IPC2010 are pretty common with a choice of Raspberry Pi Compute Modules 4 with up to 8GB RAM, 32GB flash, and optional WiFi 5 and Bluetooth 5.0, as well as a full-size HDMI video output, a Gigabit Ethernet port, and a few USB ports. What’s a little different is one FPC connector on the mainboard with both HDMI and USB for touchscreen displays. ED-IPC2010 specifications: SoM – Raspberry Pi CM4 SoC – Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5GHz with VideoCore VI GPU System Memory –  1GB, 2GB, 4GB, or 8GB RAM Storage – 8GB, 16GB, or 32GB eMMC flash Wireless – […]

BIGTREETECH Pad 7 7-inch 3D printer control display runs Klipper on Allwinner H616 SoM or Raspberry Pi CM4

BIGTREETECH Pad 7 Settings

Yesterday, I wrote about the BTT Pi V1.2 Allwinner H616 SBC designed for 3D printers, but also mentioned I had received the Pad 7 from BIGTREETECH which is a software-compatible, but more complete solution with a 7-inch display and an Allwinner H616-powered CB1 system-on-module compatible with the Raspberry Pi CM4. The BIGTREETECH Pad 7 should be more convenient to use with its integrated 7-inch touchscreen display, and if you ever decided you didn’t need it to control your 3D printer anymore, it could always be used as a small Linux computer running Raspberry Pi OS or another operating system. BIGTREETECH Pad 7 specifications: Supported modules BIGTREETECH CB1 v2.2 (included in the kit) – Allwinner H616 quad-core Cortex-A53 CPU with Mali-G31 MP2 GPU, 1GB RAM, 802.11 b/g/n WiFi 4 Raspberry Pi CM4 module with Broadcom BCM2711 quad-core Cortex-A72 CPU with VideoCore IV GPU, 1 to 8GB RAM, 0 to 32GB eMMC […]

EVerest is an open-source software stack for car charging stations

EVerest open source car charging station software

EVerest is a software project initiated by PIONIX GmbH, but now part of the Linux Foundation’s LFEnergy initiative, whose primary goal is to develop and maintain an open-source software stack for EV charging infrastructure. EVerest supports multiple standards and it will run on any device from AC home chargers to public DC charging stations. I noticed the EVerest project in an upcoming talk at the Embedded Open Source Summit 2023 entitled ” EVerest: Electric Vehicle Chargers With Open Hardware and Software” and whose abstract reads in part: You will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open-source software stack for EV charging infrastructure. Following a quick introduction to EV charging technology, with explanations of the standards, protocols, and complexities involved, the talk will go into a deep dive into how you can build your own AC charging station.

BLIKVM open-source KVM over IP works with Raspberry Pi CM4, Raspberry Pi HAT, PCIe card, and soon Allwinner H616

BLIKVM Raspberry Pi KVM

BLIKVM is an open-source KVM over IP software that helps you manage servers or workstations remotely regardless of the health of the target system, and currently working with Raspberry Pi CM4 hardware, a Raspberry Pi HAT, or a PCIe board, and a new model based on MangoPi’s Allwinner H616 CPU module is coming soon. We’ve previously written about the Raspberry Pi-based PiKVM DIY project, followed by the PiKVM v3 Raspberry Pi HAT from the same project, and now I can see there’s a CM4-based PiKVM V4 that was on Kickstarter last month and raised over $800,000… You’d think this kind of system would be rather a niche market, but there’s even demand to have a similar open-source project called BLIKVM offering many of the same features since it’s based on PiKVM, except for the option to use a PCIE card fitted with a CM4 module. Highlights of the BLIKVM project: […]

IP67-rated CM4 AI camera uses Raspberry Pi Compute Module 4 for computer vision applications

EDATEC ED-AIC2020

EDATEC ED-AIC2020 is an IP67-rated, Raspberry Pi CM4-based industrial AI camera equipped with a fixed or liquid lens and LED illumination that leverages the Raspberry Pi Compute Module 4 to run computer vision applications using OpenCV, Python, And Qt. We’ve previously written about Raspberry Pi Compute Module-based smart cameras such as the Q-Wave Systems EagleEye camera (CM3+) working with OpenCV and LabVIEW NI Vision and the StereoPi v2 (CM4) with stereo vision. But the EDATEC ED-AIC2000 is the first ready-to-deploy Raspberry Pi CM4 AI camera we’ve covered so far.

Cytron CM4 Maker Board review – Part 2: NVMe SSD, RTC, Buzzer, Grove modules, ChatGPT…

Cytron CM4 Maker board Review

We’ve already checked out Cytron’s CM4 Maker Board kit with a Raspberry Pi CM4 system-on-module and booted the system with the included 32GB “MAKERDISK” Class 10 microSD card preloaded Raspberry Pi OS in the first part of the review. For the second part of the CM4 Maker review, I’ve mostly used the 128GB NVMe SSD provided by the company and played with other features of the board including the RTC, the buzzer, some Seeed Studio grove modules, and even got help from ChatGPT for one of the Python programs I used. Booting Cytron CM4 Maker Board with the “MAKERDISK” NVMe SSD I connected several Grove modules with GPIO and I2C interfaces, a Raspberry Pi Camera Module 3, an Ethernet cable, two RF dongles for a wireless keyboard and mouse, an HDMI cable to a monitor, and finally inserted the provided 5V/3.5A USB-C power adapter. The MAKERDISK SSD comes with Raspberry […]

M5Stack CM4Stack – A tiny Raspberry Pi CM4 Linux computer with an integrated 2-inch display

CM4Stack mini PC Raspberry Pi CM4

M5Stack CM4Stack is a tiny Arm Linux mini PC based on Raspberry Pi CM4 that measures 59 x 44 x 46mm and integrates a 2-inch touchscreen display for information and control, as well as the usual ports you’d expect from a mini PC such as HDMI, USB 3.2 ports, Gigabit Ethernet, and so on. We’ve previously written about M5Stack Core and Atom controllers based on ESP32 microcontrollers, an optional 2.0-inch display, and a few GPIOs. The company has now decided to provide a similar solution with a jump in performance and interfaces with the CM4Stack development kit. CM4Stack specifications: SoM – Raspberry Pi CM4 (CM4104032) with SoC – Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz System Memory – 4GB RAM Storage – 32GB eMMC flash Wireless module with 802.11 b/g/n/ac WiFi 5 and Bluetooth 5.0 Integrated display – 2.0-inch LCD with ST7789V2 controller, touchscreen function Video Output – HDMI […]
