NComputing RX540 Raspberry Pi CM5-powered thin client supports Citrix, Microsoft AVD, WIndows 365, RDS, and more

NComputing RX540 is a thin client powered by the Raspberry Pi CM5 that works with Citrix, Microsoft Azure Virtual Desktop (AVD), Windows 365, Remote Desktop Services (RDS), and NComputing’s own vSpace Pro and VERDE VDI platforms. Omnissa Horizon integration is expected in March 2025. We first covered NComputing when the company released the RX300 Raspberry Pi 3-based Thin Client in 2017, which we reviewed with Windows Server 2016 the same year. Since then, the company introduced the RX420(HDX) Raspberry Pi 4 Thin Client compatible with Citrix HDX in 2020, and now they’ve introduced their first Raspberry Pi Compute Module-based hardware with the CM5-powered NComputing RX540 thin client, and there’s also an RX580 model with 8GB RAM and internal storage available upon request. Ncomputing RX540 specifications: SoM – Raspberry Pi Compute Module 5 SoC – Broadcom BCM2712 CPU – Quad-core 64-bit Arm Cortex-A76 processor @ 2.4GHz GPU – VideoCore VII GPU […]

TouchEye ESP32-S3 or RP2040 dual touch display board

TouchEye dual round touch display module features Raspberry Pi RP2040 or ESP32-S3 MCU (Crowdfunding)

Last December, Debashis wrote about the Waveshare Double Eye LCD module comprised of two round displays that can be useful for robotics or art projects since they can be made to look like googly eyes. The module is designed to be connected to a host MCU via an SPI interface. The TouchEye looks similar but offers larger 1.28-inch round displays (instead of 0.71-inch), and also adds a touch function. Instead of being connected to a host MCU via SPI like the Waveshare model, the TouchEye dual touch display module is a complete board with an onboard MCU that can be either a Raspberry Pi RP2040 or an Espressif ESP32-S3 that also offers WiFi and Bluetooth connectivity. Both boards also feature a USB-C port for power and programming, a microSD card slot, a GPIO breakout connector, and programmable buttons. TouchEye module specifications: MCU (one or the other) Raspberry Pi RP2040 dual-core […]

Raspberry Pi Pico SDK 2.1.1 release adds 200MHz clock option for RP2040, various Waveshare boards, new code samples

The Raspberry Pi Pico SDK 2.1.1 has just been released with official 200 MHz clock support for the Raspberry Pi RP2040 MCU, several new boards mostly from Waveshare, but also one from Sparkfun, as well as new code samples, and other small changes. Raspberry Pi RP2040 gets official 200 MHz clock support When the Raspberry Pi RP2040 was first released along with Raspberry Pi Pico in 2021, we were told the default frequency was 48 MHz, but the microcontroller could also run up to 133 MHz. Eventually, I think the Cortex-M0+ cores were clocked at 125 MHz by default, although some projects (e.g. PicoDVI) would boost the frequency up to 252 MHz. Frequencies higher than 133 Mhz were not officially supported so far, but the Pico SDK 2.1.1 changes that since the Raspberry Pi RP2040 has now been certified to run at a system clock of 200MHz when using a […]

LLMStick – An AI and LLM USB device based on Raspberry Pi Zero W and optimized llama.cpp

Youtuber and tech enthusiast Binh Pham has recently built a portable plug-and-play AI and LLM device housed in a USB stick called the LLMStick and built around a Raspberry Pi Zero W. This device portrays the concept of a local plug-and-play LLM which you can use without the internet. After DeepSeek shook the world with its performance and open-source accessibility, we have seen tools like Exo that allow you to run large language models (LLMs) on a cluster of devices, like computers, smartphones, and single-board computers, effectively distributing the processing load. We have also seen Radxa release instructions to run DeepSeek R1 (Qwen2 1.5B) on a Rockchip RK3588-based SBC with 6 TOPS NPU. Pham thought of using the llama.cpp project as it’s specifically designed for devices with limited resources. However, running llama.cpp on the Raspberry Pi Zero W wasn’t straightforward and he had to face architecture incompatibility as the old […]

24 bit ADC 8 layer Stackable HAT on Raspberry Pi

February 12, 2025February 13, 2025

Stackable HAT brings high-resolution 24-bit ADC to Raspberry Pi (Crowdfunding)

Sequent Microsystems’ “Eight 24-bit ADC 8-layer Stackable HAT” is a Raspberry Pi expansion board designed for home automation projects. It is compatible with all Raspberry Pi models with a 40-pin GPIO header and features a stackable design that provides scalability for more complex setups. It includes eight independent 24-bit ADC channels, providing ultra-high resolution for measuring small analog signals accurately. It also features programmable gain amplifiers on each input channel for amplifying weak signals and optimizing the ADC’s input range. It is stackable up to eight layers, allowing for up to 64 differential analog inputs. It provides 4A continuous and 5A peak power to the Raspberry Pi via the GPIO header. It sends data via the I2C lines, leaving all other pins free for use. Also, it supports isolated RS485 communication for long-distance connectivity. The 8-layer Stackable HAT for Raspberry Pi is suitable for precision data acquisition applications, including industrial […]

Adafruit’s PioMatter library adds HUB75 RGB LED Matrix support to the Raspberry Pi 5

The Raspberry Pi 5 brought a more powerful CPU and GPU and faster I/Os compared to the Raspberry Pi 4, as well as some incompatibilities. While the transition from a Raspberry Pi 4 to a Raspberry Pi 5 is usually painless for most applications, Adafruit notes that the ability to drive HUB75 RGB LED matrices was lost on the Raspberry Pi 5 which now relies on the Raspberry Pi RP1 peripheral control to drive GPIOs instead of the Broadcom processor directly controlling them. The company has now addressed that by using the PIO (Programmable I/O) block in the RP1 chip, yes that’s the same PIOs as found in the RP2040 or RP2350 microcontroller, to drive HUB75 RGB LED matrices from the Raspberry Pi 5, and their work can be found on the Adafruit-Blinka-Raspberry-Pi5-Piomatter repository on GitHub. The instructions to install the Adafruit Blinka Raspberry Pi 5 PioMatter library (or just […]

FlashMyPico – Raspberry Pi Pico / Pico 2 code editing and firmware flashing from a web browser

FlashMyPico website allows you to write C code, build the firmware, and flash it to your Raspberry Pi Pico, Pico W, Pico 2, or Pico 2 W directly from a web browser instead of having to check out the code from GitHub, build it in a terminal, and then manually copy the resulting binary. I’ve given it a quick with a Raspberry Pi Pico 2 board. The first step is to head over to flashmypico.com from your computer or even an Android smartphone. You’ll need a web browser that supports WebUSB, so for example, Firefox is not an option, and I eventually had to use Google Chrome instead. There’s a detect device link on the bottom left, so I clicked on that first, and my Raspberry Pi Pico 2 was detected as “RP2350 Boot” after I put it in bootloader mode. But it just told me that my board is […]
