Miniature Raspberry Pi CM4 carrier board only exposes USB-C port and 40-pin GPIO header

Mirek Folejewski’s (aka Mirko Electronics) PicoBerry is an open-source hardware, miniature Raspberry Pi CM4 carrier board with just a USB Type-C port for power, a 40-pin Raspberry Pi GPIO header, and barely anything else. At just 70x20mm, the 2-layer board only adds a few LEDs, namely the ACT/PWR LEDS and two user LEDs, and supports any Raspberry Pi CM4 module with eMMC flash, but not the Raspberry Pi CM4 Lite since the board does not include a microSD card slot. PicoBerry specifications: Supported system-on-modules – Raspberry Pi CM4 with eMMC flash, and possibly compatible SoMs such as Radxa CM5 or Pine64 SoQuartz64 USB – USB Type-C for power Expansion – 40-pin GPIO header with the same layout as on Raspberry Pi 4 or other Pi boards with a 40-pin header Misc – ACT/PWR LEDs, 2x user LEDs (green.red) Power Supply  – 5V DC/3A via USB-C port, Dimensions – 70x20mm (2-layer […]

Ubuntu 22.10 released with MicroPython and improved Raspberry Pi display support

Canonical has just released Ubuntu 22.10 “Kinetic Kudu” with improved desktop usability and performance, upgrade enterprise management tooling, and tools to optimize developer workflows, but highlights most relevant to CNX Software readers are the inclusion of MicroPython and improved embedded display support for Raspberry Pi. It feels like Ubuntu 22.04 LTS was just recently outed, but six months have already passed and Ubuntu 22.10 interim release is out. Some of the generic changes include: Toolchain updates to Ruby, Go, GCC and Rust OpenSSH server (sshd) is only activated when an incoming connection request is received to lower the memory footprint on resource-constrained devices A new debuginfod service to help developers and admins debug programs shipped with Ubuntu Landscape 22.10 beta to run and manage Ubuntu server to desktop on most architectures including Arm and RISC-V GNOME 43 with GTK4 for improved performance and consistency. Pipewire audio platform with better Bluetooth […]

Making a weather station with Maker Pi Pico Mini board and SparkFun SerLCD display

Cytron’s Maker Pi Pico Mini comes with a Raspberry Pi Pico or Raspberry Pi Pico W microcontroller board. It has the same features as the larger Maker Pi Pico including a GPIO LED, WS2812B Neopixel RGB LED, a passive piezo buzzer, programmable push buttons, and a reset button. I would like to thank Cytron for sending the Maker Pi Pico Mini board fitted with a Raspberry Pi Pico W as well as a character RGB LCD and a 3.7V Lithium Polymer battery. In this tutorial, we will show how to make an Internet connected weather station with the Maker Pi Pico Mini board using Arduino code and the OpenWeather API. We’ve already covered the Maker Pi Pico Mini board, so we’ll have a closer look at the accessories SparkFun SerLCD character display The SparkFun SerLCD is a 16×2 character display with a Microchip ATmega328P microcontroller that handles commands sent from […]

Mini Pupper 2 – Raspberry Pi 4 / CM4 robot dog adds ESP32, ROS2 support, servo feedback (Crowdfunding)

Mini Pupper 2 is an improved version of the Mini Pupper robot dog powered by a Raspberry Pi 4 introduced last year. The new model support either the Raspberry Pi 4 SBC or CM4 module, adds an Arduino programmable ESP32 wireless MCU, support for ROS2, and servo feedback. Two variants are offered with the Mini Pupper 2 implementing position servo feedback, and the Mini Pupper 2 Pro position, velocity, and torque servo feedback. Other changes common to both variants include the addition of an IMU, microphone & speaker, a touch sensor, support for autocalibration, as well as a new mobile app for control. Mini Pupper 2 specifications: CPU module – Raspberry Pi 4 SBC or Raspberry Pi CM4 system on module MCU – ESP32 WiFi and Bluetooth dual-core microcontroller programmable with the Arduino IDE Display – 320×240 LCD for facial animation Audio – Built-in Microphone and speaker Camera – Support […]

UP 4000 x86 SBC review with Ubuntu 22.04

The UP 4000 is a credit-card / Raspberry Pi-sized single board computer based on an Intel Apollo Lake processor. AAEON sent me the model with an Intel Atom x7-E3950 quad-core processor, 4GB RAM, and a 64GB eMMC flash, and in the first part of the review, I installed Ubuntu 22.04 since the board would initially only boot to the UEFI shell out of the box. I’ve now spent more time with the board, and in this article, I will report my experience with the UP 4000 SBC running Ubuntu 22.04 checking out features, performance, video playback, power consumption, and so on. Ubuntu 22.04 System info Let’s check out some information after I’ve upgraded the system to the latest packages:

Everything looks good with an Intel Atom E3950 processor detected together with 3.68GB RAM and a 56.53GB rootfs EXT-4 partition. UP 4000 features testing There may also be some issues […]
