Wemos LOLIN D32 Pro ESP32 Board Supports TFT Displays, Comes with a micro SD Card Slot

Wemos LOLIN D32 Pro

Wemos is popular for their low cost WiFi board based on Espressif SoCs. Their most popular board is ESP8266 based Wemos D1 mini  thanks to its compact form factor, low price ($5 shipped), and available add-on boards. But they’ve also launched some ESP32 in the last year or so with development boards such as Wemos LOLIN32 Lite. Their latest ESP32 board – LOLIN D32 Pro v2.00 – features ESP32-WROVER module, and beside exposing I/Os via breadboard compatible headers, also offers a micro SD card slot, a TFT display connector, and an I2C header.

Hikey 970 Documentation, HiAI DDK, Linux Firmware Images, and Support Forums

Hikey 970 board has impressive specifications with Huawei Kirin 970 SoC featuring an octa-core Arm Cortex A73/A53 processor and an Arm Mali-G72-MP12 GPU, coupled with 6GB LPDDR4x and 64GB UFS storage. It’s also one of the first broadly available developer platforms equipped with a Neural Processing Unit for artificial intelligence applications. However when it launched in April, Hikey 970 documentation was lacking, and despite the board is supposed to run both Android (AOSP) and Linux distributions such as Ubuntu or Debian, so far only AOSP is shown in the download section, with Linux distributions “coming soon”. But if you want to start as soon as possible there are still some good news. First, some documentation for the board has been released on Github, including getting started guides, hardware documentation (schematics, user manual, etc..), and some instructions to build AOSP from source code, and flash it to the UFS storage. If […]

$9 SQ8 may be the World’s Smallest Car Dash Camera / Action Camera

There are so many car dash DVRs and action cameras on the market that barely differentiate themselves on the market that I don’t usually write about those anymore. But SQ8 “mini car video recorder full HD sports DV camera” caught my eye First, because at $8.99 on GeekBuying it’s really cheap, but most importantly because it’s incredibly tiny, even smaller than JeVois computer vision camera I reviewed last year. SQ8 camera specifications: Chipset – “AnGuo” Storage – micro SD card up to 32 GB Camera 12MP CMOS image sensor for 1080p30 videos  (AVI/MJPG) 65 Degrees Wide Angle 3mm lens Motion Detection, Night Vision Audio – Built-in microphone/speacker (AAC) USB – 1x mini USB port Misc – On/off and mode buttons, reset pinhole, LED indicator Battery – 200 mAh good for about 100 minutes Dimensions – 2.2 x 2.2 x 2.0 cm Weight – 25 grams Operating Temperature –  0 – 60 […]

LiveStream #1 – Migrating to Marlin Firmware

Karl here. I’ve decided to start doing a weekly Livestream on different topics related to subjects covered on CNX Software. For the fist livestream, I will be showing the workflow that I use to migrate to newer Marlin firmware on HE3D K280 3D printer but it applies to any printer. I will also cover the calibration process for the K280. I originally did a written review of the K280 but it is sometimes hard to show concepts in writing. The livestream will take place on  June 14th @ 21:30 ET timezone, and if you are interested you can register below, or come back to this page to check it out. Karl JohnsonKarl is a technology enthusiast that contributes reviews of TV boxes, 3D printers, and other gadgets for makers.
