USB board emulates CR2032 or CR2016 coin cell battery

You can now develop CR2032 or CR2016 powered devices without having to use an actual coin cell thanks to Peter Misenko’s (Bobricius) “coin cell battery emulator CR2016/CR2032”. The USB board contains a rounded part that is compatible with CR2016 or CR2032 coin cell batteries and allows you to power your target board via USB. The board also includes holes for alligator clips to measure the current, and by extension the power consumption. Coincell battery emulator CR2016/CR2032 specifications: Power Supply 5V via Micro USB port 3V regulator 3V + GND pins for incompatible holders Power measurement – 2x alligator clip holes for Amperemeter mode (the onboard solder jumper must be open) Dimensions – Designed for a CR2016 battery (1.6 mm thick), but an adapter can be soldered for a CR2032 battery (3.2mm thick) It’s not a size fit all solution since it will only work with a specific type of battery […]

PCIe adapter adds four USB 3.2 ports to Raspberry Pi CM4 IO board

Raspberry Pi CM4 IO Boards USB 3.2 ports

Waveshare has introduced a non-standard PCIe adapter that adds four USB 3.2 ports to the Raspberry Pi Compute Module 4 IO carrier board in a way that does not take too much height. It’s non-standard as it can not be inserted directly into a typical computer PCIe slot, and Waveshare recommends a PCIe extension cable to connect it to a motherboard. Having said that It looks much better on the IO board. Waveshare USB PCIe adapter features: PCIe host interface 4x USB 3.2 Gen1 ports, USB 3.0 / 2.0 / 1.1 compatible Onboard VIA Labs VL805 chip as found on Raspberry Pi 4 SBC Power supply – 12V via PCIe connector or 4-pin header Designed for Raspberry Pi Compute Module 4 IO Board Dimensions – 82×39 mm Since it’s basically using the same design as Raspberry Pi 4 providing USB ports through the same VL805 PCIe chip, there’s no […]

Using Raspberry Pi 400 keyboard PC as a USB keyboard for your PC

Let’s try not to get confused, but you can now use Raspberry Pi 400 keyboard PC as a standard USB keyboard, optionally with a mouse attached to it, for your computer, or twisted minds may even connect it to a Raspberry Pi SBC… “But why?” you may ask. Because we can. That’s now possible thanks to work from Phil Howard (Gadgetoid), software lead of Pimoroni, and his Pi400kb project which implements a raw HID keyboard forwarder that turns the Raspberry Pi 400 into a standard USB keyboard. All you need to do is to find a USB-C to USB-A cable to connect the Raspberry Pi 400 to one of the USB ports on your computer, change some Raspberry Pi OS configuration, and install and run pi400kb. Add dtoverlay=dwc2 to /boot/config.txt in order to use the dwc2 USB device/gadget mode, and reboot your Pi 400 Load the libcomposite kernel module, get […]

M5Stack UnitV2 AI module gets USB camera and M12 camera versions

M5Stack UnitV2 is an ultra-compact Linux AI camera powered on Sigmastar SSD202D SoC with a dual-core Cortex-A7 processor @ 1.2 GHz, and 128MB on-chip DDR3 that was launched in April 2021 with a Full HD camera featuring a 68° field-of-view. M5Stack has now introduced two new models, one called M5Stack UnitV2 USB without any camera at all, instead relying on an external USB UVC camera, and the other named M5Stack UnitV2 M12 equipped with an M12 socket and shipping with both a normal focal length camera with an 85° FoV and wide-angle focal length with a 150° FoV. M5Stack UnitV2 USB M5Stack Unitv2 USB specifications: SoC – SigmaStar SSD202D dual-core Cortex-A7 processor @ 1.2 GHz with 128MB on-chip DDR3 Storage – 512MB on-chip NAND flash with around 100MB free space, MicroSD card socket Camera – N/A Audio – Built-in microphone Connectivity – 2.4GHz WIFi 4 up to 150 Mbps (RTL8188FTV), […]

Fujitsu introduces Wirepas Massive USB dongle for location tracking, IoT mesh networking

I was first introduced to Wirepas Massive mesh networking a few days ago when I covered Solidrun Solidsense N8 IoT Compact Wirepas Massive gateway comprised of an NXP i.MX 8M Nano processor running Linux and a module based on Nordic Semi nRF52832 wireless MCU handling Wirepas Massive through its 2.4 GHz radio. It turns out there’s an easy way to add the new mesh networking technology to existing gateways: USB dongles. Fujitsu has launched the FWM8BLZ09x Wirepas Massive USB dongle family, based on the more recent nRF52833 SoC, with Anchor, Tag, and Sink models. Fujitsu FWM8BLZ09x specifications: USB Dongle Types Anchor – FWM8BLZ09P Tag – FWM8BLZ09T Sink – FWM8BLZ09S Wireless MCU – Nordic Semi nRF52833-CJAA Cortex-M4 microcontroller @ 64 MHz with 8 KB RAM, 512 KB Flash, 2.4 GHz radio Connectivity Wirepas Massive mesh networking Transmit power – +8dBm max. Carrier frequency – 2,400MHz to 2,483.5MHz Modulation – GFSK Symbol rate […]

Arduino powered 5-key keypad includes a rotary encoder

JC Pro Macro - Arduino Keyboard with Rotary Encoder

There was a time when people were happy to interact with their computer with a standard keyboard and mouse. But in recent years, we’ve noticed more programmable, custom-designed keyboards with more ergonomy, a built-in touchscreen display, integrated into a multi-function USB dock/hub, as well as tiny keypads with a couple of mechanical keys to speed up specific functions. JC Pro Macro is another one of those compact USB keypads. Powered by an Arduino Pro Micro board, the keypad features five mechanical keyboard keys, and adds a rotary encoder, plus an optional I2C OLED display for debugging, and some I/Os to control external hardware like a fan. JC Pro Macro keyboard’s features and specifications: MCU board – Arduino Pro Micro compatible board with Microchip ATmega32U4 AVR microcontroller User input 5x programmable keyswitches Rotary encoder to control volume or other “rotary-y” elements, plus a 6th input switch, i.e. you can press it […]
