Arducam ToF camera adds depth sensing to Raspberry Pi for $30 (Crowdfunding)

Arducam has launched of Time-of-Flight (ToF) camera module for Raspberry Pi that enables depth sensing by capturing 3D data (at 240×180 resolution) at a distance of up to 4 meters. Arducam has launched several cameras for Raspberry Pi boards over the years, more recently the Arducam Pi HawkEye 64MP camera, but the Arducam ToF camera is quite different, as while it still connects to the MIPI CSI connector of the SBC, it is used to measure distances and depth and display 3D data. Arducam ToF camera specifications: Compatibility – Any Raspberry Pi board with a MIPI CSI connector Effective number of pixels – 240×180 Frame Rate Up to 120 fps (sensor) Up to 30 fps (when processed by a Raspberry Pi using 4-phases RAW frames) Sensor size – 1/6-inch Modulation Frequency – 75MHz/37.5MHz Viewing Angle – 70° Diagonal Light Source – 940nm VCSEL illuminator Output Formats 4-phases RAW Frame Depth […]

Infineon XENSIV PAS CO2 Shield2Go board enables carbon dioxide measurements

Infineon has added new a shied to its Shield2Go ecosystem with the XENSIV PAS CO2 Shield2Go board integrating the company’s XENSIV PAS CO2 sensor capable of measuring carbon dioxide levels. We first wrote about the Shield2Go module with the OPTIGA Trust-M evaluation kit integrating a security module, but the family also includes various sensors shield and microcontroller boards notably the XMC 2Go board. The new Shield2Go board can be used for both air quality monitoring and controlled ventilation for energy savings.

ESP32 board supports 2.4Ghz LoRa with SX1280 RF transceiver

We’ve seen plenty of ESP32 LoRa boards with the traditional 433 MHz, 868 MHz, or 915MHz frequencies, but I think LilyGO LoRa V1.8 (aka T3 V1.8) is the first ESP32 board that integrates a Semtech SX1280 transceiver for the 2.4GHz LoRa standard used for global coverage, notably maritime applications, and ranging. The ESP32 & SX1280 board also offers 26 pins for expansion, a microSD card for data storage, a 2-pin connector for batteries, a 0.96-inch OLED for information display, and comes with a 3D antenna and u.FL connector for WiFi and Bluetooth, and an SMA antenna for LoRa connectivity. LilyGO LoRa/T3 V1.8 specifications: SoC – Espressif ESP32 dual-core Xtensa LX6 processor with 2.4 GHz WiFi 4 and Bluetooth 4.2 Storage – 4MB SPI flash, microSD card slot Display – 0.96-inch OLED display with 128×64 resolution (SSD1306 I2C driver) Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps + Bluetooth 4.2 […]

MeLE Quieter3C fanless mini PC review with Ubuntu 22.04, Windows 11

MeLE’s newly launched Quieter3C is an update to their earlier Quieter3Q product which replaces one of the Type-A USB ports with a Type-C USB port and includes both power delivery and video display output, together with changing one of the HDMI ports to a mini DisplayPort. MeLE kindly sent one for review and given these are the only differences I’m only going to take a cursory look at performance benchmarks together with looking at these new features. MeLE Quieter3C hardware overview The MeLE Quieter3C is physically the same size as the Quieter3Q and consists of a 131 x 81 x 18.3mm (5.16 x 3.19 x 0.72 inches) rectangular plastic case with a metal base plate. The top half of the case has the characteristic fine grooves that mimic the fins of a heat spreader and is made of plastic rather than metal to allow reception to the WiFi antennas as […]

StarFive JH7110 RISC-V processor specifications released

With the Star64 and VisionFive 2 single board computers, we’ve already got two hardware platforms based on the StarFive JH7110 quad-core RISC-V processor, but somehow we did not get the detailed specifications of the new processor, and some details such as the presence of AI accelerators or exact PCIe specifications were lacking. Some documentation for the StarFive JH7110 processor has been released and answers some of those questions. It’s actually an SoC with six RISC-V cores, of which four 64-bit RISC-V cores run the main OS, plus a 64-bit RISC-V monitoring core, and a 32-bit RISC-V real-time core. The AI accelerators found in the JH7100 (Neural Network Engine and NVDLA) appear to be gone for good, and there are two 1-lane PCIe 2.0 interfaces up to 5 Gbps each. StarFive JH7110 specifications: CPU sub-system Quad-core 64-bit RISC-V SiFive U74 (RV64GC) processor @ up to 1.5 GHz with 32KB D-Cache, 32KB […]
