ANAVI Dev Mic is a digital omnidirectional microphone based on Raspberry Pi RP2040 MCU (Crowdfunding)

The ANAVI Dev Mic is an open-source microphone board from ANAVI Technology in Plovdiv, Bulgaria powered by the Seeed Studio XIAO RP2040 module and an omnidirectional digital microphone from STMicroelectronics. It is a compact and affordable product that outperforms USB microphones in artificial intelligence and machine learning voice applications. The design is simple and unassuming, with the Seeed Studio XIAO RP2040 module in the center, surrounded by a USB-C port for power and programming and 9 GPIO pins for extensibility. The STMicroelectronics MP23DB01HP microphone (MK1) is mounted on the top of the board with a small hole on the bottom. It is a compact, low-power, digital MEMS microphone capable of capturing sounds from different directions with very low distortion. It uses a PDM (Pulse-Density Modulation) interface created via the programmable inputs/outputs (PIO) on the RP2040. The ANAVI Dev Mic is applicable for conducting AI/ML research, building a voice recognition platform, […]

Radxa X4 SBC kit review – Part 1: Unboxing, case assembly, Ubuntu 24.04 installation

The Radxa X4 is a single-board computer that uses an Intel N100 processor instead of an Arm-based SoC found in most SBCs and also embeds a Raspberry Pi RP2040 microcontroller for GPIO control. What’s interesting is that the Radxa X4 is a small computer board with a similar form factor as the Raspberry Pi 5 SBC, but benefits from the higher performance of Intel “Alder Lake-N” Processor N100 CPU and out-of-the-box compatibility with most operating systems, except for specific features such as GPIOs. The Intel N100 board also comes with a built-in M.2 M-key socket (so no need for an extra HAT) that supports higher speed storage thanks to a PCIe 3.0 x4 interfaces, as well as WiFi 6 connectivity, making the Radxa X4 an interesting option for those looking for a small, capable computer board for home, IoT, or industrial use. The company sent us a full kit with […]

$119 MoreSense MS-06 air quality monitor features a Sensirion SCD40 sensor and an ESP32-S3 MCU

The MoreSense MS-06 is an ESP32-S3-based air quality monitor that takes CO², temperature, and humidity readings through a Sensirion SCD40 sensor which offers reliable performance and a lifespan of more than ten years. The MS-06 monitor’s results are identical to the Aranet4’s (considered best-in-class), putting it in a pretty good spot accuracy-wise. It is the latest entry in the MoreSense line of air quality monitors and comes with a more compact design and a touchscreen display. The built-in web server runs an interface that displays measurements, historical data visualizations, setup options, and firmware updates. Operation is completely local; sensor data can be stored on the device or a microSD card. The MoreSense MS-06 air quality sensor can be used to control a ventilation system, contributing to significant energy savings. This can be achieved through your home automation system or by using a smart plug. MoreSense MS-06 specifications: Microcontroller – ESP32-S3 […]

The Raspberry Pi 5 SBC is now available with 2GB RAM for just $50

The Raspberry Pi 5 has now a cheaper variant with 2GB of RAM going for just $50 following the launch of the Broadcom BCM2712 SBC in October 2023 with either 4GB or 8GB LPDDR4X-4267 SDRAM for respectively $60 and $80. At the time of the release, we also noted that cheaper variants with 1GB and 2GB RAM should become available later on simply because of the options on the silkscreen. When Eben Upton contacted CNX Software about the release of the Raspberry Pi 5 2GB RAM he explained that Raspberry Pi was “bringing the power of our most modern platform, and all of the optimisations we’ve developed since the launch of the larger memory SKUs last autumn, to a new lower price point”. Raspberry Pi 5 2GB RAM specifications: SoC – Broadcom BCM2712 (cost-optimised D0 stepping) CPU – Quad-core Arm Cortex-A76 processor @ 2.4 GHz with crypto extensions, 512KB per-core […]

Toshiba TCKE9 reusable e-fuse features a fixed over-voltage clamp with adjustable overcurrent limit

Toshiba has recently introduced the Toshiba TCKE9 reusable e-fuse (electronic fuse) series, a new lineup of e-fuse ICs that can be used repeatedly, to protect power supply lines from various electrical faults like overcurrent, overvoltage, overtemperature, and short circuits. These new chips integrate various protection features into a single chip which simplifies circuit design and reduces component count compared to how a traditional protection circuit with multiple components is designed. This new line of products offers different ICs with different voltage ratings and adjustable current settings, alongside two reset modes auto-retry and latching. All these features make this e-fuse useful for applications like laptops, wearables, audio/video equipment, and industrial applications like automation systems, robotics, and many other applications. Toshiba TCKE9 reusable e-fuse Specification Input Voltage – 2.7V to 23V (Maximum – 25V) Output Current – 0 to 4.0A (Adjustable overcurrent limit – 0.5A to 4.0A via external resistor) ON Resistance […]

Radxa ROCK 5 ITX RK3588 mini-ITX motherboard review – Building an Arm PC and NAS with Debian KDE

ROCK 5 ITX Review: Build Arm Computer NAS

In this review, I’ll show how I installed Debian on the ROCK 5 ITX mini-ITX motherboard powered by a Rockchip RK3588 octa-core Arm Cortex-A76/A55 processor, before building a computer/NAS with the Arm mini-ITX motherboard, testing various features and running benchmarks. In the first part of the review, we checked out the Radxa ROCK 5 ITX (Arm) and Jupiter (RISC-V) mini-ITX motherboards with specifications and unboxing, and the Auriga 6-Bay NAS mini-ITX chassis used in this review. I already built the computer with the Jupiter RISC-V mini-ITX motherboard, so here I simply switched the RISC-V motherboard with the Radxa ROCK 5 ITX Arm motherboard and installed a few SATA drives. Radxa ROCK 5 ITX first boot – A tricky start… Radxa provides getting started instructions on the documentation website which I mostly follow to hopefully boot within a few minutes. I had to prepare the hardware first. So I installed a […]
