Waveshare RP2040-BLE is a Raspberry Pi RP2040 module with Bluetooth LE connectivity


If you could not care less about WiFi, the Waveshare RP2040-BLE module combines a Raspberry Pi RP2040 microcontroller with an unnamed Bluetooth 5.1 dual-mode chip, and supports a USB-C add-on board useful during development. There are several Raspberry Pi RP2040 boards with a WiFi and Bluetooth module including the Raspberry Pi Pico W, but if you are only interested in using Bluetooth, the RP2040-BLE board from Waveshare may be more power-efficient and its design may be more suitable for integration into products. Waveshare RP2040-BLE specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex M0+ microcontroller up to 133 MHz with 264KB of SRAM Storage – 2MB of onboard Flash memory. Connectivity Bluetooth 5.1 dual-mode function (BLE and classic) Controlled by serial AT commands Ceramic antenna Expansion 24x through and castellated holes with 14x multi-function GPIO pins. 2x SPI, 2x I2C, 2x UART, 3x 12-bit ADC, 14 x PWM FPC connector […]

Testing AI and LLM on Rockchip RK3588 using Mixtile Blade 3 SBC with 32GB RAM

mixtile blade 3 review RK3588 AI LLM

We were interested in testing artificial intelligence (AI) and specifically large language models (LLM) on Rockchip RK3588 to see how the GPU and NPU could be leveraged to accelerate those and what kind of performance to expect. We had read that LLMs may be computing and memory-intensive, so we looked for a Rockchip RK3588 SBC with 32GB of RAM, and Mixtile – a company that develops hardware solutions for various applications including IoT, AI, and industrial gateways – kindly offered us a sample of their Mixtile Blade 3 pico-ITX SBC with 32 GB of RAM for this purpose. While the review focuses on using the RKNPU2 SDK with computer vision samples running on the 6 TOPS NPU, and a GPU-accelerated LLM test (since the NPU implementation is not ready yet), we also went through an unboxing to check out the hardware and a quick guide showing how to get started […]

MINIX Z100-0dB review – Part 2: A fanless Intel Processor N100 mini PC tested with Windows 11

MINIX Z100-0dB review Windows11

We’ve already done an unboxing and a teardown of the MINIX NEO Z100-0dB fanless mini PC powered by an Intel Processor N100 CPU, and equipped with a 16GB DDR4-3200 RAM and a 512GB M.2 SSD before quickly trying the preinstalled Windows 11 Pro operating system in the first part of the review. We’ve now had time to test Windows 11 in the MINIX Z100-0dB fanless mini PC in more detail. So we’ll report our experience in the second part of the review with features testing, benchmarks, some storage and networking performance tests, measurements of fan noise and power consumption, and more. We’ll also compare the MINIX NEO Z100-0dB against other Alder Lake-N mini PCs such as the actively-cooled GEEKOM Mini Air12 that we reviewed at the end of last year. Software overview and features testing The System->About window confirms the Z100-0dB mini PC features an Intel N100 processor at 800 […]

GEEKOM A7 mini PC review – Part 3: Ubuntu 22.04 (and Ubuntu 24.04)

GEEKOM A7 Ubuntu 22.04 Linux review

After a GEEKOM A7 mini PC unboxing and teardown, I tested the AMD Ryzen 9 7940HS mini PC in Windows 11 Pro, but I’ll now report my experience with the GEEKOM A7 running Ubuntu 22.04.4 to see our well the AMD Ryzen 9 7940HS system performs in Linux. I also had to install Ubuntu 24.04 to check the wireless module further, so I’ll report on that too. The Ubuntu 22.04 review will include features testing, several benchmarks, storage, 2.5GbE, and WiFi 6 networking performance testing, a stress test to check thermal performance, as well as fan noise and power consumption measurements. Ubuntu 22.04 installation I resized the Windows 11 partition to get an unused 500GB partition to install Ubuntu 22.04 from a USB drive. But the first time, it did not work as I was asked to disable BitLocker disk encryption in Windows 11 just like I did for the […]

Semtech AirLink XR60 is the world’s smallest rugged 5G router

Airlink XR60 world smallest rugged 5G router

Semtech AirLink XR60 is a tiny 5G router powered by a quad-core Cortex-A53 processor with up to two Ethernet ports (1Gbps and 5 Gbps), WiFi 6 connectivity, GNSS navigation, and an optional RJ45 serial port. Semtech is better known for its LoRa low-power transceivers, but the company acquired Sierra Wireless last year, so they’ll now have a wider range of wireless products to offer, and the AirLink XR60 5G gateway is the first we cover here on CNX Software since the merger between the two companies. Semtech Airlink XR60 specifications: SoC – Quad-core Arm Cortex-A53 processor Memory – 1.2 GB RAM (that should be the free memory) Storage –  1.7 GB (available storage) Networking 5G cellular Sierra Wireless EM9291 5G NR Sub-6 M.2 module Peak downlink – 2800 Mbps Peak uplink – 300 Mbps 4×4 MIMO 4x SMA antenna connectors Dual SIM (Nano-4FF) Carrier – AT&T, FirstNet 4G, T-Mobile, Verizon, […]

LibreVNA open-source USB vector network analyzer (VNA) works in the 100kHz to 6GHz range

LibreVNA Open source hardware vector network analyzer vna

Jan Käberich’s LibreVNA is an open-source hardware USB vector network analyzer (VNA) based on a Spartan-6 FPGA, an STM32 microcontroller, and RF circuitry with MAX2871 and Si5351C chips. The open-source VNA supports two channels and works in the 100kHz to 6GHz frequency range. Vector network analyzers are expensive pieces of electronic test equipment used to measure the magnitude and phase of high-frequency electrical networks costing several thousand dollars. They are commonly used in radio frequency (RF) and microwave engineering applications. Last year, we wrote that Pico Technology released PicoVNA 5 software for Linux, Raspberry Pi, and macOS instead of only providing a Windows program for their commercial PicoVNA devices. I thought it was already a good development even if it was closed-sourced, but LibreVNA goes all the way with an open-source hardware design with hardware design files, the FPGA code, STM32 firmware, and PC software (GUI) all open-source. LivreVNA hardware […]
