iWave Telematics Control Unit Supports GPS, 4G LTE, WiFi, and Bluetooth

We’ve often written about iWave Systems’ single board computers, development kits, and systems-on-module, but the company has also been offering automotive products such as a Linux based OBD-II Dongle. And they’ve just introduced a new one called Telematics Control Unit (TCU) based on an Arm Cortex-A7 processor and offering GPS, 4G LTE Cat 4/1/M1, WiFi 5, and Bluetooth 5.0 connectivity for vehicle fleet management and insurance companies that want to know how drivers behave… iWave Telematics Control Unit (TCU iW-G26) specifications: Processor – Arm Cortex-A7 based CPU @ 792MHz (likely NXP i.MX 7ULP) System Memory – 256MB DDR3L SDRAM Storage – 4GB eMMC Flash Connectivity 4G LTE Cat 4, Cat 1, Cat M1 (eMTC) 802.11b/g/n Wi-Fi 4 or 802.11b/g/n/ac Wi-Fi 5 (Hotspot & Station mode) Bluetooth 5.0 GNSS – GPS/A-GPS receiver with antenna Sensors – 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer OBD Features & Protocols 12V Power Input from TCU Port USB 2.0 device CAN 1x HS CAN bus J1962 …

RAK2287 Mini PCIe LoRaWAN Concentrator Module Supports up to 500 Nodes per km2

RAK Wireless launched its first Mini PCIe LoRaWAN concentrator module in 2018 with RAK833 mPCIe card featuring Semtech SX1301 LoRa baseband chip. It was soon followed by RAK2247 mPCIe with a very similar design but some tweaks to increase its maximum transmission power and range, and improve thermals and stability with the addition of a heatsink. The company has now introduced a new version with RAK2287 Mini PCie LoRaWAN concentrator module being mostly inspired by RAK2247 module but replacing Semtech SX1301 by Semtech SX1302 LoRa transceiver that’s suppose to reduce current consumption (and heat), lower the BoM cost, and able to handle a higher amount of traffic. The new mini PCIe card also adds u-blox ZOE-M8Q GPS system-in-package to provide GNSS functionality. RAK2287 key features and specifications: LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-end Tx power – up to 27dBm Rx sensitivity – down to -139dBm @ SF12, BW 125 kHz LoRaWAN® 1.0.2 compatible. LoRa band coverage …

MEGA-RTD Raspberry Pi HAT Offers up to 64 Resistance Temperature Detectors (Crowdfunding)

Sequent Microsystems like to make stackable Raspberry Pi HATs. After their stackable 4-relay board allowing for up to 32 relays controlled by a Raspberry Pi board, the company has now launched MEGA-RTD 8-channel RTD Raspberry Pi HAT enabling up to 64 resistance temperature detectors via 8x MEGA RTD board stacked on top of a Raspberry Pi board. If you haven’t heard about this type of temperature sensors, we wrote a post explaining the advantages and drawbacks of resistance temperature detectors last year. Basically, those temperature sensors contain a resistor that changes resistance value as their temperature changes, and support much wider temperature ranges than traditional temperature sensors such as DHT22 while keeping a <0.1°C accuracy. The price of the sensors themselves is similar to traditional sensors, but the total price is more expensive since they require extra hardware to measure the resistance/voltage value. MEGA-RTD key features and specifications: MCU – STMicro STM32F030 Arm Cortex-M0 microcontroller handling I2C commands from Raspberry …

ThinkCentre M75n IoT Nano Desktop Features a 6W AMD Athlon Silver 3050e Processor

Earlier today, we wrote about AMD 3015e dual-core/quad-thread Zen processor with 6W TDP found in some upcoming education laptops from Lenovo. We also noted that two other recent 6W AMD processors had been introduced by the company AMD 3020e and AMD Athlon Silver 3050e. When looking for AMD 3020e I got ACER ASPIRE A314-22-A8ST 14″ laptop with 4GB RAM and 256GB SSD listed for 9,590 Baht ($309 inc. 7% VAT) – but out of stock – on several Thai websites, but after switching to a US VPN all product reference disappeared, except for Lenovo Ideapad 3 soon getting an AMD 3020e model. None of the laptops are available now, but at least that means AMD does not only target the education market with its 6W SKUs. But when I searched for AMD Athlon Silver 3050e platforms, I realized Lenovo made an announcement last June about ThinkCentre M75n IoT Nano Desktop designed for Internet of Things applications in manufacturing, retail, and …

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 …

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 …
