CrowView Note Review – A 14-inch laptop shell designed for Raspberry Pi 5 and Jetson Nano Developer kit

Elecrow CrowView Note is a laptop shell with a 14-inch Full HD display, an 84-key QWERTY keyboard with a touchpad, built-in speakers and microphone, and a 5,000 mAh battery that’s specially designed for the Raspberry Pi 5 and the Jetson Nano Developer Kit thanks to adapters. However, it can be used with any machine with either a full-featured USB-C port or spare USB and HDMI ports. So it works with any Raspberry Pi model, Windows, Mac OS, or Linux computers, Android smartphones, PS4/PS5 game consoles, and more. This type of laptop shell has been around for years with the first one being the Laptop shell for the Motorola Atrix 4G smartphone introduced in 2011, and more recently Nexdock launched a range of laptop shells such as the Neckdock XL 15.6-inch touchscreen display and wireless charging. The CrowView Note differentiates itself with its low price and direct compatibility with the Raspberry […]

Bus Pirate 5XL and 6 hardware debugging tools utilize Raspberry Pi RP2350A and RP2350B microcontrollers

The Bus Pirate 5XL and 6 are open-source hardware debugging tools respectively based on Raspberry Pi RP2350A and RP2350B and designed to simplify interaction with various bus protocols like 1-Wire, I2C, SPI, UART, several LEDs, and more. The idea is to send commands to a chip or sensor and get the response, without writing a single line of code making it ideal for hardware hacking and tinkering. The devices feature buffered I/O pins with voltage and current measurement, a programmable power supply with current limiting, an RGB LCD for pin status and info, and an auxiliary header for connecting logic analyzers. All these features make this device useful for applications like debugging circuits, prototyping projects, and reverse engineering devices. The new devices are updates to the Bus Pirate 5 based on Raspberry Pi RP2040 MCU. You’ll find Bus Pirate specifications for the three models in the table below. The original […]

A closer look at Raspberry Pi RP2350’s HSTX high-speed serial transmit interface

The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs. We’ll also check out some programming examples in C and MicroPython. The high-speed serial transmit (HSTX) interface is detailed in the RP2350 datasheet starting on page 1118 where it reads “The high-speed serial transmit (HSTX) interface streams data from the system clock domain to up to 8 GPIOs at a rate independent of the system clock”. Reading further, we also learn that it runs at 150 MHz enabling up to 300 Mbps per pin with DDR output operation, or a combined 2,400 Mbps over 8 pins if I […]

Mixtile Edge 2 Kit review with Home Assistant, 2-in-1 Zigbee & Z-Wave mPCIe module

We received the Edge 2 Kit IoT gateway on the Rockchip RK3568-powered Edge2 single board computer (SBC) and a 2-in-1 Zigbee and Z-Wave mPCIe card from Mixtile which we will be reviewing from the perspective of smart home applications using Home Assistant open-source home automation framework. Let’s dive into the details. Unboxing Mixtile Edge 2 Kit CNX Software previously reported on the Mixtile Edge 2 Kit in 2022 and you can check the detailed specifications and block diagram in that earlier article. Since then, Mixtile has found a wider range of applications for the device and is also promoting it as an Edge AI Box that performs AI object detection using the Edge 2 Kit (or the more powerful Mixtile Blade 3) using the built-in NPU (Neural Processing Unit) with up to 1 TOPS of AI performance for tasks such as object detection. Let’s unbox it and take a closer […]

Google Pigweed SDK now supports Raspberry Pi RP2350 microcontroller

Raspberry Pi Pico 2 (RP2350) with Enviro+ pack hat.

Google Pigweed, a collection of open-source libraries for embedded software development, now supports the Raspberry Pi RP2350 MCU and comes as a software development kit (Google Pigweed SDK). These libraries, also called modules, are building blocks that make embedded software development faster and more reliable. It targets tiny 32-bit microcontrollers such as STMicro STM32L452, Nordic Semi nRF52832, and the Raspberry Pi Pico line of microcontrollers. The library components have shipped in Google Pixels, Nest thermostats, robots, satellites, and drones. On August 8, the Pigweed project was released as a software development kit (SDK) in developer preview with official support for Raspberry Pi RP2350 and the associated Pico 2 development board. The new release uses the Bazel build system – a feature upstreamed into the Pico SDK by the Google Pigweed team – and a complete, open-source Clang/LLVM toolchain. The Google Pigweed SDK includes sample code, modules, and a comprehensive tutorial […]

Solder Party’s “RP2350 Stamp” modules features Raspberry Pi RP2350A or RP2350B microcontroller

Solder Party’s RP2350 Stamp is an update to the company’s tiny RP2040 Stamp module based on a Raspberry Pi RP2350A, and they also introduced the RP2350 Stamp XL module that makes use of the extra GPIO pins on the RP2350B, and a “RP2xxx Stamp Carrier XL” carrier board taking either module. RP2350 Stamp and RP2350 Stamp XL The RP2350 Stamp has exactly the same layout as the RP2040 Stamp and mostly benefits from the more powerful Cortex-M33 cores, additional memory, and security features, while the XL variant adds more GPIOs, footprint for a PSRAM chip, as well as UART and SWD connectors. Both come with a 16MB SPI flash for storage.
