Xtherm II TS2+ review – A 256×192 thermal imager tested with an Android smartphone

Xinfrared Xtherm II TS2+ Review Android

Shortly after I wrote about the Mustool MT13S 2-in-1 thermal imager and multimeter, Xinfrared asked me if I wanted to review the Xtherm II TS2+ thermal imager for smartphones. They offer versions that work for Android or iOS smartphones, so the company sent me the Android version of the Xtherm II TS2+ for review. After listing the key features and specifications, I’ll go through an unboxing, and report my experience using the thermal imager with the OPPO A98 5G smartphone running Android 14. Xtherm II TS2+ specifications Minimum focus – 8mm Resolution – 256×192 Pixel Pitch – 12μm FOV – 44.9° x 33.4° Image Frame Rate – 25Hz NETD (Noise Equivalent Temperature Difference) – ≤40mK@25°C, F#1.0 MRTD (Minimum Resolvable Temperature Difference) – ≤500mK@25°C,F#1.0 Temperature Range Measurements- -20°C ~ +450°C with ±2°C or ±2% reading accuracy Operating – -20°C ~ +50°C Temperature Correction – Manual/automatic Power Consumption – <350mW Dimensions – […]

Golioth expands its free tier for developers with unlimited IoT devices, OTA updates, 1GB bandwidth

Golioth IoT platform unlimited devices

When we first wrote about the Golioth IoT development platform with ESP32 and nRF9160 devices support in 2022, we noted they offered a free Dev Tier account for up to 50 devices, 10 MB of LightDB data with a 7-day retention policy, and other limitations. The company has now decided to remove many of the limitations from the free developer tier without any limit to the number of IoT devices and also added other benefits: Unlimited Device Connections: Empowering developers to scale projects without constraints. Over-the-air (OTA) Device Firmware Updates (DFU) with 1GB monthly bandwidth 1,000,000 Monthly Log Messages up to 200MB Free data retention Time series – 30 days Logs: 14 days The main limitations compared to paid plans are that only one project can be created and a single seat (single loading) is available, so it’s not possible to have a team of users with different permissions like […]

Samsung unveils 256GB microSD Express card with up to 800MB/s read speeds

SamSung MicroSD Express 256GB cards

Samsung has just started sampling its 256 GB SD Express microSD card (aka microSD Express card) with a sequential read speed of up to 800 MB/s through its PCIe/NVMe interface. The SD Express standard was first introduced in the SD specification ver 7.0 in 2018 adding pads for PCIe/NVMe interfaces in full-sized SD cards before the microSD Express standard was introduced in the SD 7.1 specification the following year. Since then, the SD association further improved the standard promising ever faster SD Express speeds up to 4GB/s and microSD Express speeds up to 2GB/s. Saying the adoption of the new SD Express and microSD Express standards has been slow would be an understatement, and the Samsung 256GB microSD Express card looks to be the world’s first such storage device. Looking at full-size SD Express cards, I could only find one on Amazon for $59.99 with 256GB capacity, 820 MB/s read […]

Panthor open-source driver for Arm Mali-G310, Mali-G510, Mali-G610, and Mali-G710 GPUs to be part of Linux 6.10

Panthor open-source Arm Mali G610 GPU driver linux

Collabora has been working on the Panthor open-source GPU kernel driver for the third-generation Arm Valhall GPU (Arm Mali-G310, Mali-G510, Mali-G610, and Mali-G710) for around two years, and the code has just been merged in drm-misc meaning it should be part of the upcoming Linux 6.10 release sometime in July 2024. Many regular readers must already be familiar with the Panfrost open-source driver for Arm Mali GPUs as we’ve covered its development progress over the years. Panthor is a new kernel driver specific to the 3rd gen Valhall GPUs that still relies on the Panfrost driver residing in userspace, as explained by Boris Brezillon from Collabora. Furthermore, the existing Gallium “Panfrost” driver in Mesa has also received a merge request adding support for those GPUs (10th gen Arm Mali = 3rd gen Arm Mali Valhall) meaning popular targets such as the Rockchip RK3588 SoC with an Arm Mali-G610 MP4 GPU […]
