Miniature Raspberry Pi CM4 carrier board only exposes USB-C port and 40-pin GPIO header

Mirek Folejewski’s (aka Mirko Electronics) PicoBerry is an open-source hardware, miniature Raspberry Pi CM4 carrier board with just a USB Type-C port for power, a 40-pin Raspberry Pi GPIO header, and barely anything else. At just 70x20mm, the 2-layer board only adds a few LEDs, namely the ACT/PWR LEDS and two user LEDs, and supports any Raspberry Pi CM4 module with eMMC flash, but not the Raspberry Pi CM4 Lite since the board does not include a microSD card slot. PicoBerry specifications: Supported system-on-modules – Raspberry Pi CM4 with eMMC flash, and possibly compatible SoMs such as Radxa CM5 or Pine64 SoQuartz64 USB – USB Type-C for power Expansion – 40-pin GPIO header with the same layout as on Raspberry Pi 4 or other Pi boards with a 40-pin header Misc – ACT/PWR LEDs, 2x user LEDs (green.red) Power Supply – 5V DC/3A via USB-C port, Dimensions – 70x20mm (2-layer […]

Lyra V2 open-source audio codec gets faster, higher quality and compatible with more platforms

Lyra V2 is an update to the open-source Lyra audio codec introduced last year by Google, with a new architecture that offers scalable bitrate capabilities, better performance, higher quality audio, and works on more platforms. Under the hood, Lyra V2 is based on an end-to-end neural audio codec called SoundStream with a “residual vector quantizer” (RVQ) sitting before and after the transmission channel, and that can change the audio bitrate at any time by selecting the number of quantizers to use. Three bitrates are supported: 3.2 kps, 6 kbps, and 9.2 kbps. Lyra V2 leverages artificial intelligence, and a TensorFlow Lite model enables it to run on Android phones, Linux, as well as Mac and Windows although support for the latter two is experimental. iOS and other embedded platforms are not supported at this time, but this may change in the future. It gets more interesting once we start to […]

Using SenseCraft firmware for no-code programming on Wio Terminal

In the conclusion of our SenseCAP K1100 Sensor Prototype kit review with LoRaWAN and Vision AI, the author suggested that it would be great if SeeedStudio could develop a new firmware that can connect without coding instead of using Arduino programming: I had to rely on my knowledge and experience with LoRaWAN to transmit data wirelessly over long distances. That’s because LoRaWAN has a more complicated connection process than Wi-Fi or Bluetooth. It would be great if Seeed Studio could develop a new firmware that can connect without any coding It did not take long, as SeeedStudio very recently released the first version of SenseCraft open source smart sensor software for no-code sense, process, and uplink that happens to be compatible with the Wio Terminal part of the SenseCAP K1100 development kit. So let’s test the new SenseCraft firmware together. SenseCraft navigation keys We can use Wio Terminal’s joystick as follows: […]

ELLO LC1 – A 2mm thin DIY “computer” based on Microchip PIC18 8-bit MCU

We often write about business card or credit card-sized boards, but it’s only true for 2D dimensions, as most boards are over a centimeter thick, with possibly the thinnest we’ve covered being the Khadas Edge2 SBC that’s just 7mm thick. So Kn/vD took it upon himself to build a DIY computer that was really about the size of a credit card, and came up with the ELLO LC1 based on a Microchip PIC18 8-bit microcontroller, featuring an integrated display and keyboard, and powered by a coin-cell battery. It’s just 2mm thin. ELLO LC1 specifications: MCU – Microchip PIC18 (PIC18F47Q83-I/PT) 8-bit microcontroller with 13KB RAM and 128KB flash, out of which 64KB are reserved as user file storage Display – 20×4 character text panel (Display Visions EADOGM204N) Keyboard – 48x touch panels on the PCB Expansion – 12-pin unpopulated header for debugging (ICSP) and GPIO expansion Misc – Power button Power […]
