Open-source hardware USB Type-C industrial camera features Lattice Crosslink NX FPGA

Open-source hardware USB Type-C camera

Gaurav Singh, acting as Circuit Valley, has designed an open-source hardware USB 3.0 Type-C industrial camera with three boards: one to capture data through a CMOS sensor,  another based on a Lattice Crosslink NX FPGA to handle image processing, and finally, a board equipped with an Infineon FX3 USB 3.0 controller for sending the video data to the host. This design allows the DIY camera to be extremely flexible, as for instance, you could keep the FPGA and USB board, and simply change the sensor board for a better/different camera. A 3D printable enclosure is also provided, and the camera supports C-mount lenses, so the lens can also be easily changed as required. Here’s what the final result looks like. Camera specifications: Sensor board Sensor for example Sony IMX290, IMX327, or IMX462 Oscillator FPGA/Host board interface – High-density connector with I2C, 4-lane MIPI with clock, I2C, a few other control […]

ShaRPiKeebo handheld Linux computer based on Raspberry Pi Zero (2) W ships with a LoRa radio (Crowdfunding)

Raspberry Pi Zero portable Linux computer with LoRa

Morpheans ShaRPiKeebo is a portable Linux computer based on Raspberry Pi Zero W or Zero 2 W SBC that reminds me of the Allwinner R8 powered PocketCHIP handheld computer that was introduced in 2016, and was quite popular (for a niche product) at the time. The ShaRPiKeebo comes with a physical QWERTY keyboard, a daylight-readable screen, and Wi-Fi & Bluetooth connectivity, but also adds a 433 MHz LoRa radio that should make it usable as an off-the-grid communicator. Just like PocketCHIP, the ShaRPiKeebo can be used for system administration, retro-gaming, pen testing, STEM education, and all sort of maker projects. ShaRPiKeebo specifications: Supported SBCs via 40-pin GPIO header – Raspberry Pi Zero W, Raspberry Pi Zero 2 W, and (maybe) compatible SBCs like Radxa Zero or Banana Pi M2 Zero Display – 2.7- inch SHARP memory display (LS027B7DH01) with 400×240 resolution, low-latency, low-power Connectivity 802.11 b/g/n WiFi 4, Bluetooth 4.2 […]

LimeSDR Mini 2.0 USB SDR board gets an upgrade to Lattice Semi ECP5 FPGA (Crowdfunding)

LimeSDR Mini 2

The LimeSDR Mini is an open-source hardware full-duplex USB SDR board based on Intel Altera Max 10 Altera FGPA that was introduced in 2017 on Crowd Supply and raised close to $2 million US dollars. Since it has been used in various projects including digital TV transmitters. Lime Microsystems is now back on Crowd Supply with the similar-looking LimeSDR Mini 2.0 replacing the MAX 10 FPGA with 16K logic gates with a more powerful and capable Lattice Semiconductor ECP5 FPGA with 44K logic gates while keeping the company’s LMS7002 RF transceiver. LimeSDR Mini 2 specifications: FPGA –  Lattice Semi ECP5 (LFE5U-45F) with 44K logic gates, 108 sysMEM blocks (18kb), 1,944 Kb embedded memory, 351 Kb distributed RAM bits Storage –  4 MB flash memory for data; 2x128KB EEPROM for RF transceiver MCU firmware and data RF Lime Microsystems LMS7002M RF transceiver Tx & Rx SMA connectors Frequency range – 10 […]

u-blox XPLR-IOT-1 explorer kit embeds cellular IoT, Wi-Fi, BLE, GNSS, and sensors for IoT evaluation

XPLR-IoT-1 IoT evaluation plaform

u-blox XPLR-IOT-1 explorer kit is an all-in-one IoT evaluation platform with cellular IoT, Wi-Fi, Bluetooth Low Energy, and GNSS, plus some sensors to evaluate various IoT products and enable proofs of concepts such as logistics container trackers, industrial automation, sensor-to-cloud applications, and fleet management solutions. The device’s main module is the u-blox NORA-B106 with a dual-core Arm Cortex M33 microcontroller and Bluetooth LE 5.2 radio that host the application software and control the other modules, namely the SARA-R510S module for LTE-M and NB-IoT cellular connectivity, NINA-W156 2.4 GHz Wi-Fi module, and the MAX-M10S GNNS module. The XPLR-IOT-1 platform is also equipped with an accelerometer, a gyroscope, a magnetometer, and temperature, humidity, pressure, and ambient light sensors. u-blox XPLR-IOT-1 specifications: Main MCU – Nordic Semi nRF5340 dual-core Arm Cortex M33 @ 128/64 MHz with 512 + 64 kB RAM memory and 1024 + 256 kB flash (found in NORA-B106 module) Wireless […]

Panfrost now offers a fully-conformant OpenGL ES 3.1 implementation for Mali-G57 (Valhall) GPU

Panfrost Mali-G57 OpenGL ES 3.1

The Mali-G57 GPU part of the Valhall family, and found in several Arm processors such as MediaTek MT8192 and MT8195 SoC powering some Chromebooks, is now supported by the Panfrost open-source driver with a fully-conformant OpenGL ES 3.1 implementation. Last year, Collabora updated Panfrost with support for OpenGL ES 3.1 on Midgard (Mali T760 and newer) and Bifrost (Mali G31, G52, G76) GPUs, and also announced having started working on Valhall GPUs. One part of the work was done in the summer of 2021 with some reverse-engineering work on Mali-G78 GPU’s instruction set, and this has culminated with a fully-conformant OpenGL3.1 for Mali-G57 GPU. Interestingly, it’s not been released by Collabora directly, but through an organization called “Software in the Public Intenerest, Inc.” (or SPI for shorts) which happens to be a non-profit organization incorporated on June 16, 1997, and described as: a non-profit corporation registered in the state of […]

Nokia 1680 phone gets new PCB with MIPS SoC, runs mainline Linux

Notkia Nokia 168x MIPS Linux

Reimu NotMoe has designed the “Notkia” PCB based on Ingenic X1000E MIPS processor with 64MB built-in RAM and following the exact same dimensions as the PCB found in Nokia 168x phones (1680, 1681, 1682), and allowing the phone to run mainline Linux. The board also comes with 32MB NOR flash, a 4GB SLC NAND flash, and supports LoRa, 2.4 GHz WiFi, Bluetooth, and GNSS connectivity, but no cellular modem. Combining Nokia 168x phone with Notkia PCBA creates a phone with the following specifications: SoC – Ingenic X1000E single-core XBurst MIPS processor @ 1.0 GHz (2200+ CoreMark) with 64MB RAM Storage – 32MB NOR flash + 4GB SLC NAND flash Display – 2.0-inch 240×320 IPS LCD, 3/4 visible (Replaces the original 128×160 TFT screen in the phone) Camera – 5MP camera with auto focus (only available in the Nokia 1680 case) Audio – Yamaha MA-3 (YMU762) music synthesizer and regular I2S […]

hm-panelizer – A KiCad companion GUI tool for panelizing PCBs

panelizer for KiCad

Gerard (aka halfmarble) has released hm-panelizer open-source software allowing for a panelization of PCBs via a simple GUI interface and doubling as a Gerber file viewer.  He’s mostly tested it with PCBs designed in KiCad 6.x, but it should also work with design files from other tools. Note that hm-panelizer is just a side project, and Gerard released it as an open-source project in hopes that it might be useful to users and the community will contribute to it. The project relies on kivy cross-platform library, pygame and pycairo libraries, as well as pcb-tools and pcb-tools-extension projects. There are some requirements for the utility to work on with your PCB : Use the metric system The PCB Gerber files must use Altium/Protel filename extensions The board outline gerber file (.gm1) must be present “Disable aperture macros” when exporting Gerber files (this may not be needed for simple designs and only […]

CherryUSB – A lightweight USB device/host stack for embedded systems

CherryUSB USB stack for embedded systems

CherryUSB is a lightweight open-source USB device/host stack for embedded systems with one or more USB interfaces. The stack implements various class drivers such as CDC, HID, MSC, audio, video, and so on. It’s apparently part of Boufallo Lab SDK (e.g. for BL702 MCU), and has been ported and tested with WCH CH32V307 RISC-V MCU, STMicro STM32F4, and Nuvoton NUC442 Cortex-M4 microcontroller, as well as a two Arm Cortex-M3 microcontrollers I’ve never heard of: EastSoft ES32F3 and MindMotion MM32L3xx.
