STMicro VL53L1X Time of Flight (ToF) Sensor Extends Distance Measurement Range up to 4 Meters

STMicroElectronics VL53L0X ToF (Time-of-flight) range sensor is a tiny chip that can accurately and quickly measure distance up to 2 meters using laser light.  I had the chance to test the sensor via TinyLIDAR board connected Arduino and Raspberry Pi, and found it was a great little sensor. TinyLIDAR includes an STM32 MCU, but you can also find standalone board for as low as about $4 shipped on Aliexpress. However, if 2 meters is too short a range for your project, the good news is that STMicro has now launched VL53L1X ToF “FlightSense” sensor with a range of up to 4 meters. VL53L1X is pin-to-pin compatible with VL53L0X, so existing PCBs could be re-used with the new sensor. STMicro VL53L1X main specifications: Emitter: 940 nm invisible laser (Class1) SPAD (single photon avalanche diode) receiving array with integrated lens Low-power microcontroller running advanced digital firmware Distance Ranging up to 4 meters […]

Status of Embedded GPU Ecosystem – Linux/Mesa Upstream Support (ELC 2018 Video)

The Embedded Linux Confernce is on-going, and the Linux Foundation has been uploading videos about talks in a timely manner on YouTube. I checked out at RISC-V keynote yesterday, but today I’ve watched a talk by Robert Foss (his real name, not related to FOSS) from Collabora entitled “Progress in the Embedded GPU Ecosystem”, where he discusses open source software support in Linux/Mesa from companies and reverse-engineering support. The first part deals with the history of embedded GPU support, especially when it comes to company support. Intel was the first and offers very good support for their drivers, following by AMD who also is a good citizen. NVIDIA has the Nouveau driver but they did not really backed it up, and Tegra support is apparently sponsored by an aircraft supplier. Other companies have been slower to help, but Qualcomm has made progress since 2015 and now support all their hardware, […]

Diamond Systems Zeta is a Miniature SBC Based on Bay Trail/Apollo Lake COM Express Mini Modules

Diamond Systems, a Silicon valley based company providing embedded computing solutions for transportation, energy, aerospace, defense, manufacturing, medical and research market, has recently introduced Zeta single board computer comprised of a baseboard, a choice of COM Express Mini type 10 modules based on Intel Bay Trail or Apollo Lake processor, and a heatspreader for cooling. The company explains the small size and high feature density of the solution make it particularly suitable for mobile applications. The SBC also supports a wide range 6-36VDC input voltage, and works in -40 to +85°C temperature range. Zeta SBC specifications: COM’s Processor and System Memory Intel Atom Bay Trail E3825 dual core processor @ 1.33GHz  with 2GB RAM Intel Atom Apollo Lake E3940 quad core processor @ 1.6GHz with 4GB RAM Intel Pentium Apollo Lake N4200 quad core processor @ 1.1GHz (burstable to 2.5GHz) with 8GB RAM Storage – 1x mSATA socket , 1x […]

Hologram Introduces Global IoT eSIM Chip

Hologram provides a SIM card for IoT projects that can be used in most of the world, and I own a developer SIM card that’s very convenient for reviews and evaluation with 10MB free data per month, which I used for example in a recent 3G HAT board for Raspberry Pi. The company also manage network by software, so they were on of the first SIM providers to enable 4G LTE Cat M1 and NB-IoT without changing anything to the SIM card itself. Since everything is programmable, not tied to any specific service provider, the SIM card form factors may not be the most convenient, and instead for a lower form factor, and possibly better reliability Hologram eSIM based on MFF2 form factor may be a better solution for new projects. The chip measures just 6x5mm with 0.67mm thickness, and would be soldered on the board of your cellular IoT […]

Emcraft Introduces NXP i.MX 8M SoM and $299 Starter Kit

I first discovered Emcraft Systems in 2011 through their work porting uCLinux to Arm Cortex M3/M4 microcontrollers, and since then the company has kept on working microcontroller software and hardware, but also moved to Arm Cortex A class solutions. Like most embedded systems companies, Emcraft engineers have also designed their own NXP i.MX 8M system-on-module, but while many have still not announced pricing, and/or show “in development” or “early product announcement” in their product page, Emcraft has started taking pre-order for their i.MX 8M SoM Starter Kit for $299, with shipping scheduled for May 21, 2018 or before. Let’s check out SOM-IMX8M specifications first: SoC – NXP i.MX8M Quad processor with 4x Cortex A53 cores, 1x Cortex-M4F core, and a Vivante GC7000Lite GPU System Memory – 512MB to 4GB DDR3L/LPDDR4 SDRAM Storage – 4 to 64GB eMMC flash Connectivity – Wireless module supporting 802.11 a/b/g/n/ac 2×2 MIMO WiFi, Bluetooth 4.2, […]

$70 UP AI Core mini PCIe Card Features Intel Movidius Myriad 2, Supports Tensorflow and Caffe Frameworks

AAEON’s Up Board has given us some affordable Intel development boards over the years with products such as the Cherry Trail based UP Board, or Apollo Lake powered UP Squared board among others, that are competitively priced against equivalent Arm development boards. The company has now launched a new UP AI Edge family, which will include hardware based on Intel Altera FPGA or Intel Movidius VPU (Vision Processing Unit). Their first product is based on the latter, more exactly Movidius 2 2450 VPU, and instead of being a standalone board, UP AI Core is a mini PCIe card that can fit into any 64-bit Intel board or computer. UP AI Core card specifications: SoC – Intel Movidius Myriad 2 2450 VPU System Memory – 512MB DDR SDRAM Mini PCIe edge connector Dimensions – 51 x 30 mm Host computer/board requirements System Memory – 1GB RAM or more Storage – 4GB […]

STMicro Introduces Two STM32 Discovery Kits with 2G/3G or 4G LTE-IoT Cat M1/NB1 Connectivity

Embedded World 2018 trade fair will take place on  on take place on February 27 – March 1 in Nuremberg, Germany, and we’re starting to see some company announce new products and solutions for the embedded market. STMicro has just announced their showcase their very first cellular development kits at the event, based on a display-less variant on their 32L496GDISCOVERY Discovery board with cellular add-on boards: P-L496G-CELL01 Discovery kit with with a 2G/3G modem P-L496G-CELL02 Discovery kit with with an LTE-IoT Cat M1 (eMTC) / NB1 (NB-IoT) / 2G model Now the company has not started designed their own cellular modem, but instead relying on QUECTEL modems.

Embedded Linux Conference & IoT Summit 2018 Schedule

The Embedded Linux Conference 2018 and the OpenIoT Summit 2018 will jointly take place next month, on March 12 – 14, 2018 in Portland, Oregon, USA. The former is a “vendor-neutral technical conference for companies and developers using Linux in embedded products”, while the latter is a “technical conference for the developers and architects working on industrial IoT”. The Linux Foundation has already published the schedule, and it’s always useful to learn what will be discussed about even for people who won’t attend. With that in mind, here’s my own virtual schedule with some of the talks I find interesting / relevant to this blog. Monday, March 12 10:50 – 11:40 – Progress in the Embedded GPU Ecosystem by Robert Foss, Collabora Ltd. Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have […]
