6W AMD 3015e Dual-Core “Zen” Processor Shows Up in Lenovo Laptops

While AMD has done a good job with their Ryzen processors based on Zen architecture, the company did not provide alternatives to low-cost, low-power Intel Gemini Lake processors with the closest equivalent being the 15W AMD Athlon 3000-series processors. But this may be about to change, as Lenovo has now unveiled two new education laptops, namely Lenovo 100e 2nd gen and Lenovo 300e 2nd gen, powered by a previously-unannounced 6W AMD 3015e processor, and expected to become available in September 2020 for $219 and up. AMD 3015e key features and specifications: CPU – 2x cores, 4x threads @ 1.2 GHz / 2.3 GHz (Boost) GPU – Vega 3 Graphics @ 600 MHz Cache – 1MB L2 cache, 4MB L3 cache Memory I/F – Single-channel DDR4 up to 1,600 MHz Video – HDMI and DisplayPort Peripheral Interfaces – PCIe 3.0 TDP – 6W Process – 14nm Based on the product page, the processor is part of the “AMD 3000 Series Mobile …

Comfile Launches 15-inch Industrial Raspberry Pi Touch Panel PC Powered by RPi CM3 Module

Three years ago, we noted Comfile has made 7-inch and 10.2-inch touch panel PC’s powered by Raspberry Pi 3 Compute Module. The company has recently introduced a new model with a very similar design except for a larger 15-inch touchscreen display with 1024×768 resolution. ComfilePi CPi-A150WR 15-inch industrial Raspberry Pi touch panel PC still features the CM3 module, and the same ports including Ethernet, USB ports, RS232, RS485, and I2C interfaces accessible via terminal blocks, and a 40-pin I/O header. ComfilePi CPi-A150WR specifications: SoM – Raspberry Pi Compute Module 3 Lite (CM3L) with Broadcom BCM2837 quad-core Arm Cortex-A53 processor @ 1.2 GHz with VideoCore IV GPU, and 1GB RAM Display – 15″ LCD with 1024 × 768 resolution, 16.7 million colors, pressure-sensitive touch screen (resistive type) Audio – Stereo Audio Output Connectivity – 10/100M Ethernet, optional WiFi via USB dongle USB – 3x USB 2.0 ports Serial – 1x RS232C terminal block, 1x RS485 terminal block Expansion 40-pin header socket …

MINIX Unveils USB-C Hub with 960GB SSD, 100W USB Charger

MINIX, the Hong Kong company, is well-known for its Android media hubs and Windows 10 mini PC‘s but in recent years they’ve started designing accessories for Windows & Mac computers and laptops. In the past, we’ve checked out MINIX NEO C Plus USB-C Adapter, an M.2 SSD card pre-loaded Windows 10 Pro for N42C-4 Mini PC, and another USB-C hub with integrated 120 or 240GB SSD. The company has now unveiled four new accessories with three USB-C hubs, including one with a 480GB or 960GB SSD, and one compact 100W USB charger using the latest Gallium Nitride (GaN) technology. This morning, I received two pairs of USB-C hubs with different colors and two 100W USB chargers. The model I did not get – MINIX NEO Storage Pro – is specifically made for Apple MacBook Air and MacBook Pro with built-in SSD storage, HDMI 2.0 up to 4K @ 60 Hz, Thunderbolt 3 and USB 3.0 ports. But that’s all good …

ESPurna ESP8266 Automation Firmware Gets Support for BME680 Sensor’s Precise Indoor Air Quality Measurements

Bosch BME680 is a 4-in-1 air quality sensor measuring relative humidity, barometric pressure, ambient temperature, and gas (VOC) levels. It’s found in boards such as STM32 based Metriful Sense or Nordic Thingy:91, and Bosch Sensortec published an Arduino library based on “Bosch Sensortec Environmental Cluster (BSEC) Software” to provide precise calculations temperature, humidity, pressure, and indoor air quality (IAQ). BSEC proprietary algorithms can provide indoor air quality data as good as more expensive CO2 sensors according to a recent presentation by the company. Max Prokhorov, lead ESPurna maintainer, and Rui Marinho noticed none of the popular open-source ESP8266 automation firmware including ESPurna, Tasmota, and Esphome supported BME680 sensor just yet. So they decided to work together to add BME680 sensor support via BSEC library to ESPurna firmware, and now it’s very easy to use as you just need to define BME680_SUPPORT=1 before compiling the firmware. You’ll find the now-merged pull request here. The feature was previously discussed in Tasmota, but …

Linux 5.8 Release – Main Changes, Arm, MIPS, and RISC-V Architectures

Linus Torvalds has just released Linux 5.8: So I considered making an rc8 all the way to the last minute, but decided it’s not just worth waiting another week when there aren’t any big looming worries around. Because despite the merge window having been very large, there really hasn’t been anything scary going on in the release candidates. Yeah, we had some annoying noise with header file dependencies this week, but that’s not a new annoyance, and it’s also not the kind of subtle bug that keeps me up at night worrying about it. It did reinforce how nice it would be if we had some kind of tooling support to break nasty header file dependencies automatically, but if wishes were horses.. Maybe some day we’ll have some kind of SAT-solver for symbol dependencies that can handle all our different architectures and configurations, but right now it’s just a manual pain that occasionally bites us. Anyway.. Aside from silly header …

Intel powered 2.4-inch Mini PC’s Show up as Alternatives to CHUWI LarkBox

Leaving HDMI PC sticks aside, we started to see really small, pocket-sized Intel mini-PCs last year with ECS LIVA Q2 micro PC with a dual-core N4100 Gemini Lake processor and measuring 70x70x33.4 mm. CHUWI managed to design an even smaller Gemini Lake Mini PC with Larkbox mini PC powered by a Celeron J4115 quad-core processor and measuring 61x61x43mm (2.4″ x 2.4″ x 1.7″). It looks like they may have launched a new 2.4-inch Mini PC form factor, as at least two other models with pretty much the same dimensions, but different specifications, have come to our attention. XCY X51 2.4-inch Mini PC Specifications: SoC – Intel Celeron N4100 quad-core Gemini Lake processor @ 1.1 / 2.4 GHz with Intel UHD Graphics 600; 6W TDP System Memory – 8GB LPDDR4 Storage – 128GB M.2 2242 SSD, MicroSD card slot Video Output – HDMI 2.0 up to 4K @ 60 Hz Audio – 3.5mm audio jack, digital audio via HDMI Connectivity – …
