Pico QwiicReset board adds Reset button and Qwiic connector to Raspberry Pi Pico

Pico QwiicReset

Pico QwiicReset is a tiny add-on board for the Raspberry Pi Pico that adds a Reset button as well as the Qwicc connector to more easily connect I2C modules to the popular MCU board. The lack of a Reset button on the Raspberry Pi Pico has always been an issue since the reset pin is used to flash the firmware, so people have tried various ways to add a Reset button to the Pi Pico board. The Pico QwiicReset is like an extension of the Pimoroni “Captain Resetti” button with an extra Qwiic connector. The Pico QwiicReset board is shown soldered to a Raspberry Pi Pico board above, but it’s also compatible with the Raspberry Pi Pico W and it works with or without headers soldered to the board. But you may noticed the Debug header is partially covered on Pico W, which means the add-on board cannot be used […]

Orange Pi Zero 2W – A Raspberry Pi Zero 2W alternative with up to 4GB RAM

Orange Pi Zero 2W

As its name implies the Orange Pi Zero 2W is an alternative to the Raspberry Pi Zero 2W with basically the same features and form factor, but equipped with a slightly more powerful Allwinner H618 quad-core Cortex-A53 clocked at 1.5 GHz, and more RAM options from 1GB to 4GB. The new Orange Pi board comes with a mini HDMI port, two USB-C ports, WiFi 5 and Bluetooth 5.0 wireless module, a microSD card for the OS, a 16MB SPI flash for the bootloader, the usual 40-pin Raspberry Pi GPIO header, and a 24-pin “function” connector used for expansion boards and located where the camera connector is on the Pi Zero 2W. Orange Pi Zero 2W specifications: SoC – Allwinner H618 quad-core Arm Cortex-A53 processor @ up to 1.5GHz with 1MB L2 cache and Arm Mali-G31 MP2 GPU with support for OpenGL ES 1.0/2.0/3.2, OpenCL 2.0, Vulkan 1.1 System Memory – […]

Libre Computer AML-S905X-CC-V2 SBC directly installs Linux images from the Internet

Libre Computer AML- S905X-CC-V2 SBC

Libre Computer AML-S905X-CC-V2 “Sweet Potato” is a “new” Amlogic S905X SBC following the Raspberry Pi 3B form factor and that will eventually directly boot Linux images downloaded from the Internet using the Libre Computer OS Tool (LOST). I wrote “new” in quotes because the single board computer is an update to the Potato board (AML-S905X-CC) introduced in 2017 with just a few hardware changes. But that’s because Libre Computer focuses on the software side and all/most of their boards can now run mainline Linux and have support for features such as LOST whose support is set to be implemented by November. Libre Computer AML-S905X-CC-V2 SBC specifications with changes in bold or strikethrough: SoC – Amlogic S905X quad-core Arm Cortex-A53 processor @ 1.5 GHz with penta-core Arm Mali-450MP GPU, and Amlogic Video Engine 10 VPU System Memory – 2GB DDR4 (OEM can request 1GB) Storage 1x microSD card slot with UHS […]

Haxophone – A Raspberry Pi-based electronic saxophone with mechanical keys (Crowdfunding)

Raspberry Pi Saxophone Mechanical Keys

The Haxophone is an unusual Raspberry Pi expansion board that transforms the popular SBC into a travel saxophone using mechanical keys.

Raspberry Shake HAT brings earthquake monitoring to the Raspberry Pi SBC

Raspberry shake kit

Raspberry Shake is a family of Raspberry Pi HATs and full seismograph and infrasound monitors designed to enable earthquake monitoring on the popular single board computer Raspberry Pi Shake and Boom (for acoustic monitoring) HATs have been around for a few years, but I only learned about it now through an article on The MagPi Magazine where Branden Christensen, Business Steward, and Mike Hotchkiss, Marketing Director, were interviewed, so I decided to have a closer look. Four main models of the Raspberry Shake are available: RS1D vertical motion seismograph with a single motion velocity sensor to detect earthquakes RS3D vertical & lateral motion seismograph with one vertical & two lateral motion velocity sensors to measure earthquakes of all magnitudes RS4D “strong motion seismograph with one vertical motion velocity sensor to detect earthquakes, plus one extra vertical and two lateral accelerometer sensors for powerful earthquakes RS&BOOM seismograph & infrasound monitor that […]
