PiFinger is a Fingerprint HAT for Raspberry Pi (Crowdfunding)

“There’s a HAT for that” they say, or something close to it… We’ve covered many HAT expansion for Raspberry Pi boards over the years, but so far, I don’t think we’ve seen any HAT with a fingerprint sensor, probable because tiny USB fingerprint readers are a thing. But if you’d like a HAT with a built-in fingerprint sensor, the guys at SB Components have you covered with PiFinger HAT equipped with a 2D capacitive fingerprint sensor and a small display. The expansion board is also powered by a Nuvoton Cortex-M23 MCU with Arm TrustZone support and on-chip crypto-accelerator. PiFinger specifications: SoC – Unnamed Nuvoton Arm Cortex-M23 microcontroller with Arm Trustzone (likely NuMicro M2351 since it’s made for fingerprint applications) Display – 0.91-inch OLED display Sensor – 2D capacitive fingerprint sensor with 176×176 resolution connected to MCU over SPI Host interface USB to computer UART up to 115,200 baud + GPIO via 40-pin Raspberry Pi header UART via 40-pin Raspberry Pi […]

Mesa 20.3 released with Raspberry Pi 4 V3DV driver, Panfrost Bifrost support

We’ve previously reported that the Vulkan 1.0 conformant V3DV driver for Raspberry Pi 4 and other Broadcom BCM2711 based platforms was part of Mesa 20.3 open-source graphics framework. But at the time, it was still under development. The good news is that Mesa 20.3 has now been released, and there’s much more than Raspberry Pi 4 support, as Collabora informed us the release also included Arm Mali Bifrost GPU support via the open-source Panfrost driver. The latter was made possible thanks to the work by Alyssa Rosenzweig and Boris Brezillon, with Alyssa going into details in a recent blog post on Collabora. More work is still needed with better performance and OpenGL 3.1 being the focus in the months ahead. But there were also many other changes in Mesa 20.3 as reported by Phoronix: OpenGL 4.6 and Vulkan 1.2 APIs support Initial support for Intel Gen12 Alder Lake graphics and AMD Dimgrey Cavefish and VanGogh graphics Lavapipe Vulkan CPU-based implementation […]

HotDive converts your smartphone into a dive computer and underwater camera (crowdfunding)

Many recent phones are fitted with a pretty good camera, and some are waterproof, but not quite enough to go snorkeling or diving. If you could, your phone could also double as a dive computer, and that’s exactly what HotDive provides: a waterproof enclosure for your smartphone allowing you to dive up to 80 meters deep, and convert your phone in a dive computer, underwater camera, and fill light at a fraction of the cost of specialized diving equipment. HotDive enclosure includes an independent auto-pump air extraction system creating a vacuum for your smartphone to make sure all photos are clear of fog, as well as a fill light to take clear photos even during night dives. The fill light is made of CREE LED lights delivering 800 lumens, and providing with 130° illuminance and 5800-6500K sunlight-like color temperature. The HotDive Pro version includes hardware to create a built-in dive computer, namely a solution based on Nordic Semi ultra-low power […]
