RAKwireless open sources RUI3 multi-target IoT development platform

Rakwireless RUI3 open source IoT development platform

RAKwireless has made its RUI3 IoT software development platform open-source so that customers or users can implement “nice-to-have” features on top of the features already implemented by the company which could make it even more versatile in a wider range of IoT scenarios. Introduced in 2022, the RAK Unified Interface v3, or RUI3 for shorts, is a modular IoT platform based on the Arduino SDK with additional functions for IoT connectivity and low power that supports a variety of devices and applications. So developers can learn the language, code once, and use the same software on multiple WisBlock core platforms including Nordic Semi nRF52, STM32, ESP32, and Raspberry Pi RP2040 instead of having to juggle between different the Arduino BSP, the ESP-IDF framework, Nordic nRF Connect SDK, or Raspberry Pi C SDK. Users could already use the RUI3 firmware with the RAK3172 (STM32), RAK4630/RAK4631 (nRF52), or RAK11720 (Apollo3) WisBlock Core […]

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 […]

Comparing the latency of various wireless standards

If you’ve ever wondered which wireless standard may deliver the smallest lag (latency) when transmitting small packets, we’ve now gotten an answer thanks to Scott at Electric UI who benchmarked various wireless links in common MCU development boards. More specifically the following hardware and wireless standards were tested: SiliconLabs 10×0-GM RF+8051 microcontroller with 240–960 MHz EZRadioPRO transceiver running SiK firmware HopeRF RFM95W LoRa module (on an Adafruit Breakout board) connected to an STM32F429 MCU Nordic Semi nRF24L01 2.4GHz transceiver module ESP32 board for ESP-NOW and WiFi testing is shown as ESP32 WS (WebSockets) or ESP32 TCP in the chart below. Raspberry Pi boards were also used for comparison ESP32-C6 board for 802.15.4 transfers (Thread) ESP32 and HC-05 modules for Bluetooth SPP (Serial Port Profile) ESP32 board with NimBLE and Bluedroid stacks and nRF52 for Bluetooth LE testing Here are the results for 12 bytes, 128 bytes, and 1024 bytes data transfers.
