Waveshare PCIe to USB 3.2 HAT+ adds four USB ports to Raspberry Pi 5

Waveshare ‘PCIe to USB 3.2 HAT+’ is an expansion hat that adds four USB 3.2 ports to the Raspberry Pi 5. The HAT+ features real-time power status monitoring and software-controlled USB power management, along with an onboard EEPROM for storing HAT ID and product data. The HAT is mounted on top of the Raspberry Pi cooler and has an airflow vent to help keep the Pi cool. This new module leverages the HAT+ standard to add 4 additional USB 3.2 ports to the Raspberry Pi 5. Previously, boards like PineBerry Pi HAT+, Geekworm X1003/X1004, and Mcuzone MPW7 have used the HAT+ standard for various attachments, such as converting the Pi 5’s PCIe into an NVMe SSD adapter, enabling access to Google’s TPU, or adding a PCIe x16 socket. Waveshare  PCIe to USB 3.2 HAT+ Specifications PCIe x1 Gen2 mode Only supports Raspberry Pi 5 Model B. Equipped with VL805 original […]

Radxa Penta SATA HAT adds up to five SATA drives to the Raspberry Pi 5 for NAS applications

The Radxa Penta SATA HAT leverages the PCIe interface on Raspberry Pi 5  SBC to add up to five 2.5-inch or 3.5-inch SATA drives through four SATA connectors and an eSATA connector and enables NAS designs with the latest SBC from Raspberry Pi Limited. The Radxa’s Penta SATA HAT was initially launched in 2019 as an accessory for the Rock Pi 4 SBC powered by a Rockchip RK3399 processor and an M.2 PCIe socket since Raspberry Pi competitors have been exposing PCIe interfaces for years. It turns out the exact same Penta SATA HAT design can be reused with the Raspberry Pi 5 by providing a new PCIe FPC cable and updating the configuration scripts. Radxa Penta SATA HAT for Raspberry Pi 5 specifications: 4x SATA interfaces + 1x eSATAp for up 100TB storage via 5x 2.5″ or 3.5″ HDD/SSD Host Connection – Flat cable with 2-lane PCIe 2.1 via […]

PineBerry Pi launches five additional HAT+ boards for the Raspberry Pi 5 with 2.5GbE, GbE, M.2 NVMe, and more

PineBerry Pi was the first company to launch a Raspberry Pi HAT+ board making use of the Raspberry Pi 5’s PCIe FPC connector with the Hatdrive! M.2 HAT for the Raspberry Pi 5 along with the HatDrive! Bottom expansion board that goes underneath the Raspberry Pi 5 SBC. The company has now launched five additional HAT+ boards for the Raspberry Pi 5 with various PCIe (NVMe/AI modules) and networking (2.5GbE, GbE) options. Here’s the list with basic specifications: HatNET! 2.5G –  2.5GbE for the Raspberry Pi 5 using a Realtek RTL8125BG controller, dedicated MAC address range (i.e. not randomly assigned), and an RJ45 jack with Activity and Link LEDs HatDrive! NET 1G – Gigabit Ethernet (Realtek RTL8111H) and M.2 M-Key socket for NVMe 2230,2242 SSD. Implemented through an ASMedia PCIe Gen 2 switch and booting with the SSD is not supported at this time.

Android 15 Developer Preview released – What’s New?

Google has just released the first Android 15 Developer Preview with some improvements related to privacy and security, the addition of the partial screen sharing feature, camera and audio improvements, and some new performance optimization that developers can leverage when running games or other demanding applications. User privacy and security in Android 15 Android 15 features the latest version of the Privacy Sandbox on Android to improve user privacy while enabling personalized advertising experiences for mobile apps, the Heatlth Connect by Android adds support for new data types related to fitness, nutrition, and more, and the File integrity manager implement new APIs making use of the fs-verity feature that was added to the Linux 5.4 kernel so that files can be protected by custom cryptographic signatures. Partial screen sharing is a completely new feature in Android 15 that allows users to share or record an app window rather than the […]

Ovrdrive USB is an open-source, privacy-oriented USB flash drive that can self-destruct (Crowdfunding)

We have previously covered the Tillitis Tkey, an open-source security key in a USB-C case but the Ovrdrive USB stick is not a security key. It is a simple, plain USB flash drive with a special security feature. It will appear completely blank unless you plug this drive in three times in quick succession. The Ovrdrive flash drive is aimed at journalists in repressive areas and security researchers but may be useful to other security and open-source hardware enthusiasts. As for how it works, the Ovrdrive has two identical circuits connected to the ATtiny24A microcontroller that controls the rapid plug-in functionality. When the flash is plugged in, the microcontroller powers on, and the CHG1 node goes high, charging C3 through D2. The pin will remain high for a while and then slowly discharge via R1 and body resistance. C3 and the identical C14 will remain high through power cycling/a quick […]

Add two M.2 NVMe SSDs to Raspberry Pi 5 with Geekworm X1004 HAT+

We’ve seen a range of PCIe HAT(+) for the Raspberry Pi 5 taking one NVMe SSD, but Geekworm X1004 is different as it can take up to two standard M.2 2280 SSDs over the Pi 5’s PCIe connector and 40-pin GPIO header. The official Raspberry Pi 5 M.2 HAT+ is not available yet, but we already have an embarrassment of choice with products such as the PineBerry Pi HatDrive, Waveshare PCIe To M.2 HAT+, Pimoroni NVMe Base, and the Geekworm X1003. The latest X1004 adds even more options with support for two M.2 SSDs for up to 8TB storage, although this may not make that much sense on the Pi 5 as we’ll discuss further below. Geekworm X1004 specifications: Supported SBC – Raspberry Pi 5 only Chipset – ASMedia ASM1182e PCI express packet switch with 1x PCIe x1 Gen2 upstream port and 2x PCIe x 1 Gen2 downstream ports 2x […]
