Microchip PIC18-Q24 8-bit MCU focuses on security and supports Multi-Voltage I/O (MVIO)

The newly introduced Microchip PIC18-Q24 8-bit MCU implements security measures such as the Programming and Debugging Interface Disable (PDID) feature and optional support for an immutable bootloader, as well as support for Multi-Voltage I/O (MVIO) to interface with digital inputs or outputs at different operating voltages without the needs for level shifters. While it’s fun to find a new MCU platform that you can hack via serial, JTAG, or other debug interfaces, it can be a security issue, and the Microchip PIC18-Q24 aims to make that impossible by disabling programming and debugging interfaces and the 8-bit microcontroller also offers an option to make the bootloader impossible to modify once a specific configuration bit has been set. Microchip PIC18-Q24 key features and specifications: MCU core – 8-bit C compiler optimized RISC core @ up to 64 MHz Memory – Up to 4 KB of Data SRAM Memory Storage – Up to […]

DIN rail mount works with all Raspberry Pi boards and compatible SBC’s with a 40-pin GPIO header

DIN rail mounts or mountable enclosures for the Raspberry Pi have been available for years with products such as the RailPi 2.0 enclosure or TerraPi’s DIN rail mount, but PlasmaDan’s DINPi RACK adds another option that happens to be compatible with any Raspberry Pi board, be it model A, model B or Zero. Since there’s no software involved, it will also with other SBCs with a 40-pin Raspberry Pi GPIO header and the same mounting holes as the Raspberry Pi SBCs, and DINPi RACK also supports one Raspberry Pi HAT or up to two Raspberry Pi pHATs, also known as uHATs (Micro HAT), plus there’s an extra 40-pin right angle for further example. The board received CE & UKCA certifications, is RoHS compliant (lead-free), and is manufactured by a UL 796 certified manufacturer. This is what the DINPi RACK looks like with a Raspberry Pi Zero W and a Raspberry […]

Radxa ROCK 3B Rockchip RK3568 SBC combines Pico-ITX and Raspberry Pi form factors

Radxa ROCK 3 Model B, or ROCK 3B for shorts, is a “PI-CO ITX” SBC powered by a Rockchip RK3568 SoC that combines the benefits of Pico-ITX and Raspberry Pi form factors in the sense that the 100x72mm board features all main ports on the rear side and supports expansion through a 40-pin Raspberry Pi-compatible GPIO header and several M.2 sockets for storage and wireless modules. The ROCK 3B is the younger, but bigger brother of the ROCK 3A business card-sized SBC introduced in 2021, still with an RK3568 CPU and up to 8GB LPDDR4, but the board features two gigabit Ethernet ports, an M.2 B Key socket for 4G LTE/5G cellular modules, an M.2 PCIe 3.0 x1 socket for an M.2 2280 SSD not necessitating an expansion board, besides the M.2 Key-E socket for WiFi 6. ROCK 3B specifications: SoC – Rockchip RK3568(J) CPU – Quad-core Cortex A55 processor […]

GEEKOM Mini IT13 review – Part 3: Ubuntu 22.04 tested on an Intel Core i9-13900H mini PC

We published the review of the Core i9-13900H powered GEEKOM Mini IT13 mini PC in Windows 11 Pro earlier this week and have now installed Ubuntu 22.04 and tested the machine with the Linux-based operating system in detail with benchmarks, features testing, networking and storage performance tests, power consumption, and thermal performance which we will report in this third and final part of the review. Installing Ubuntu 22.04 on GEEKOM Mini IT13 I shrank the Windows partition by about 500 MB in Disk Management in Windows 11 (Disk 1) in order to install Ubuntu 22.04.3 in dual boot configuration. The installation went smoothly using WiFi 6 to retrieve newer files and I could log in to the Ubuntu 22.04 desktop. But there was a trick, as I had to go to Windows first to select “Advanced Startup” and select Ubuntu on the next boot since the GRUB menu would just […]
