Swissbit Secure Boot for Raspberry Pi Relies on MicroSD Card and optional USB Stick

Swissbit secure boot solution for Raspberry Pi consists of an 8GB or 32GB “PS-45u DP” Micro SD card pre-loaded with their secure firmware, and offering the following key features: Security policies with flexible and configurable authentication Access protection with configurable retry counter Protects Raspberry Pi boot loader Encrypts user and boot code to protect license, know-how, and IP The boot image can be set read-only to prevent unauthorized modification Restricting the access to data on the card by various configurable security policies: PIN or USB or NET policy Use 8GB PU-50n DP USB stick as 2nd authentication for secure boot Works with Raspberry Pi 2 and 3B+ (I suppose Raspberry Pi 4 support should come soon enough) Note that we previously wrote about an open-source Raspberry Pi 4 UEFI+ACPI firmware to make the board SBBR-compliant and support features such as UEFI secure boot, but Swissbit secure boot is completely unrelated […]

HART-IP Developer Kit Leverages Raspberry Pi 3B+, Off-the-Shelf Add-on Boards for Industrial Field Communication

Have you ever heard about the bi-directional HART communication protocol? I haven’t, but I should probably have as there’s an installed base of over 40 million HART-enabled instruments according to FieldComm Group who owns the protocol and the organization is comprised of 375 corporate members working on process automation instrumentation, systems, and services. HART stands for Highway Addressable Remote Transducer. The organization is also maintaining the more recent (2009) HART-IP IP-enabled version of the HART field communication protocol and just launched HART-IP Developer Kit whose hardware is comprised of a Raspberry Pi 3B+ SBC and off-the-shelf add-on boards mounted on a DIN Rail mount. List of all hardware components: Raspberry Pi 3B+ SBC DSLRKIT Power Over Ethernet PoE HAT (around $20 on Aliexpress) Waveshare Raspberry Pi High-Precision AD/DA (about $30) DINrPlate DIN Rail Mount. MicroSD card On the software side, the system runs Ubuntu MATE 18.04 64-bit preloaded on the MicroSD […]

Argon One Case Brings All Raspberry Pi 4 Connectors on One Side

Due to its small size, the Raspberry Pi 4 board has Ethernet and USB ports on one side, and micro HDMI ports, AV port, and USB-C port on another side. This may not be an issue for most people, but having all ports on one side may make cable management easier. Argon One case for Raspberry Pi 4 makes that feat possible thanks to an adapter board that brings HDMI and AV ports on the left side of the USB ports, and an extra power expansion board does the same for the USB-C port plus adds a power button. Argon One comes in a kit with the following components: Aluminum top cover, black bottom AR1 power board AR1 AV board with micro HDMI inputs and outputs, AV port input and output Fan Power button Thermal pads for the processor and memory chip for passive cooling via internal heatsinks built into […]

Raspberry Pi HQ Camera Features a 12MP Sensor, Supports Interchangeable Lenses

The Raspberry Pi Foundation introduced the first official Raspberry Pi camera in May 2013. The $25 camera module came with a 5MP sensor and connected via the board’s MIPI CSI connector. Then in 2016, the company launched version 2 of the camera with an 8MP sensor. The foundation has now launched a much better camera called Raspberry Pi HQ Camera (High-Quality Camera) with a 12MP sensor, improved sensitivity, and support for interchangeable lenses both in C- and CS-mount form factors. The module itself is equipped with a Sony IMX477 sensor, a milled aluminum lens mount with integrated tripod mount and focus adjustment ring, a C- to CS-mount adapter, and an FPC cable for connection to a Raspberry Pi SBC. RPi HQ camera specification: Sensor – 12.3MP Sony IMX477R stacked, back-illuminated sensor; 7.9 mm sensor diagonal, 1.55 μm × 1.55 μm pixel size Output – RAW12/10/8, COMP8 Back focus – Adjustable […]

“New” Raspberry Pi 3B v1.2/v1.3 May be Incompatible with Cases with Embedded Heatsink

As we’ve recently seen with Raspberry Pi 4 v1.2, the Raspberry Pi Foundation will sometimes provide new revisions of their boards with small differences or fixes that most users won’t notice, so they will not make announcements about those minor revisions. Somebody on the RPi forums noted there may be a “new version of Raspberry Pi 3B“, and the discussion points out there are actually two such revisions that are mass-produced from various companies. It turns out the Foundation also posted PCN (Product Change Notices) on the product page of their boards, so we can know exactly what has changed and when. The fist PCN for v1.2 board is dated November 1, 2018, and explains the SoC has changed switching from BCM2837 to BCM2837B0 found in Raspberry Pi 3B+ but with frequency limited to 1.2 GHz. The PCN further explains the timing of the change: The new part will be […]

Connect up to 32 Relays to Raspberry Pi with a Stackable 4-Relay Board (Crowdfunding)

People have been playing with off-the-shelf relays on Raspberry Pi boards ever since it was released in 2012, and over the years, some companies have maybe Raspberry Pi-specific relay boards such as Strawberry4Pi and Pi-OT. Two years ago, Sequent Microsystems introduced a stackable 8-Relay board enabling up to 64 relays to be connected to a single Raspberry Pi board. The 8-relay board only supported 24V/2.5A, and the company is now back on Kickstarter with a 4-relay board with 250V/10A line-switching relays that can offer up to 32 relays by stacking 8 boards connected to one Raspberry Pi board via the 40-pin I/O header. The board comes with four Songle 250V/10A relays, 3-pin pluggable connectors that accept 18 to 22 AWG wires, and a 5V/3A power supply is recommended. If you stack multiple relay board a beefier power supply may be required. Here are some power consumption numbers provided by the […]

Raspberry Pi 4 vs ODROID-C4 Features Comparison

Yesterday, Hardkernel launched ODROID-C4 Amlogic S905X3 SBC as an update to ODROID-C2 SBC launched in 2016. We’ve seen the board can compete with Raspberry Pi 4 4GB board thanks to benchmarks released by Hardkernel, but since those boards are so versatile, meaning they can be used in a variety of applications, it’s impossible to benchmark all use cases. One way to find out which board might be right for your application without going through benchmarks is to look at a list of features for each, and that’s exactly what we’ve done in this post. Let’s get straight to the Raspberry Pi 4 (4GB RAM) vs ODROID-C4 comparison table. Features/Specs Raspberry Pi 4B (4GB) ODROID-C4 Release date 24th June 2019 23rd April 2020 SoC Broadcom BCM2711 quad-core Cortex-A72 @ 1.5 GHz (overclockable to 2.0+ GHz) with NEON, FPU Amlogic S905X3 quad-core Cortex-A55 processor @ 2.0 GHz with NEON, FPU, Armv8 Crypto […]
