Raspberry Pi 4 2GB gets a price hike to $45, 1GB version coming back for $35

Raspberry Pi 4 Price Hike

We’ve been used to getting better hardware for cheaper or in the case of Raspberry Pi model B boards a stable $35 price tag since 2021 with gradual improvements to the hardware. Many companies already had to hike prices for their board due to supply constraints, and Raspberry Pi Trading has become the latest victim of the increase in components with the Raspberry Pi 4 with 2GB RAM going back to its original $45 price tag, and the re-introduction of the Raspberry Pi 4 1GB for $35. We are told this is temporary, and once everything settles the Raspberry Pi 4 2GB should sell for $35 as was the case since last year. This is the very first price hike in Raspberry Pi (short) history. The supply shortage is not as bad as it seems though, as Raspberry Pi Trading expects to sell around seven million units this year, or […]

LEGO Technic meets Raspberry Pi with the Build HAT

Raspberry Pi Build HAT with LEGO Technic

A new official Raspberry Pi expansion board is introduced today. The Built HAT provides four connectors for LEGO Technic motors and sensors from the SPIKE Portfolio, as well as an 8V DC jack to power both the Raspberry Pi and LEGO motors, sensors, LED matrix, and more. Designed in collaboration with LEGO Education, the Build HAT features the Raspberry Pi RP2040 dual-core ARM Cortex M0+ MCU for I/O control, and will enable more complex models benefiting from more powerful Broadcom BCM2xxx processors, as well as a Python library for easy programming. Build HAT key features and specifications: MCU – Raspberry Pi RP2040 microcontroller for low-level control of LEGO Technic devices 4x LPF2 connectors for LEGO Technic motors and sensors included in the SPIKE Portfolio 40-pin GPIO header for connection to Raspberry Pi 4 Model B, 3B+, 3B, 3A+, or Pi Zero family (Raspberry Pi 400 not supported) Misc – 2x […]

Nintendo Switch Lite Raspberry Pi CM4

StonedEge and Dmcke5 have come up with an incredibly well-designed Raspberry Pi CM4 handheld console that looks like a Nintendo Switch Lite “clone”, and that can run Dreamcast and PSP emulators at full speed using RetroPie. The RetroLite CM4 The design includes a 5-inch display, speakers, all buttons, joysticks, and D-PAD controlled via a custom Arduino board, a micro HDMI port to connect an external display, and a 4000 mAh LiPo battery charged over the USB Type-C port, and it seems to work, albeit we are told there’s still some more work to do. RetroLite CM4 specifications include: Linux capable SoM – Raspberry Pi CM4 Lite module with custom copper heatsink and fan Storage – MicroSD card slot All-on-one PCB with Arduino for inputs, TI bq24292i for battery management controlled via a PIC16F15234 MCU, and backlight boost converter circuitry Display – ~5-inch LCD IPS screen Audio – Stereo speakers User […]

OpenBSD 7.0 adds 64-bit RISC-V, improves Apple Arm silicon support

OpenBSD 7.0

OpenBSD 7.0, the 51st release of the UNIX-like operating system, was outed on October 14, 2021, with the introduction of 64-bit RISC-V support for HiFive Unmatched and PolarFire SoC Icicle Kit boards, as well as further improvements to ARM64 targets, notably for Apple Silicon Macs, although it’s not quite ready for general use yet. You’ll find the complete list of new features and updates on the OpenBSD website, but here are some of the highlights: New platforms – OpenBSD 7.0 add 64-bit RISC-V support Extended platforms arm64 Improvements to Apple Silicon Macs support USB 3, NVMe storage, GPIO driver, power management, etc… Enabled LEDs for the LAN7800 chip as found on the Raspberry Pi 3 Model B+. Added Type-C PHY controller found on the Rockchip RK3399. Implemented multicast support to Marvell ARMADA chips Various other changes to mips64, amd64, armv7, powerpc64 Kernel improvements Enabled dynamic tracker (dt) for GENERIC kernels […]

Raspberry Pi 4, Rockchip RK3399 SBC’s get Arm SystemReady IR certification

RockPro64 RK3399 Arm SystemReady IR certification

The first hardware platforms getting Arm SystemReady IR certification for IoT Edge applications were announced a few months ago with namely NXP i.MX 8 Mini evaluation kit and Compulab IOT-GATE-IMX8 gateway being able to run off-the-shelf operating system images such as Fedora IoT, OpenSuSE Leap 15.3, and Debian 11 thanks to UEFI firmware. But following PinePhone Pro Linux smartphone announcement, and Pine64 October update, we also learned that Rockchip RK3399 based RockPro64 was also Arm SystemReady IR certified, and check Arm’s website directly revealed it was joined by Lenovo Leez P710 “Gateway” SBC, as well as Raspberry Pi 4 and Pi 400 platforms. Let’s check the details and see what off-the-shelf images each board has been tested with. Pine64 RockPro64 RK3399 SBC achieved SystemReady IR v1.0 Level 1 certification meaning it complies with some waivers and workarounds found in the errata document. The board has been successfully tested with Fedora […]

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

Raspberry Pi CM4 IO Boards USB 3.2 ports

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 […]

Using Raspberry Pi 400 keyboard PC as a USB keyboard for your PC

Raspberry Pi 400 USB keyboard

Let’s try not to get confused, but you can now use Raspberry Pi 400 keyboard PC as a standard USB keyboard, optionally with a mouse attached to it, for your computer, or twisted minds may even connect it to a Raspberry Pi SBC… “But why?” you may ask. Because we can. That’s now possible thanks to work from Phil Howard (Gadgetoid), software lead of Pimoroni, and his Pi400kb project which implements a raw HID keyboard forwarder that turns the Raspberry Pi 400 into a standard USB keyboard. All you need to do is to find a USB-C to USB-A cable to connect the Raspberry Pi 400 to one of the USB ports on your computer, change some Raspberry Pi OS configuration, and install and run pi400kb. Add dtoverlay=dwc2 to /boot/config.txt in order to use the dwc2 USB device/gadget mode, and reboot your Pi 400 Load the libcomposite kernel module, get […]
