KidBright32 Board is Thailand’s BBC Micro:Bit Equivalent

BBC Micro:Bit board was first announced in July 2015. Designed for STEM education, the board was then offered to UK schools in March 2016, and a few months later UK store would start selling it worldwide. It’s now available pretty much anywhere, and you can likely find it in a local store or online. The Thai government must have seen this, and thought to themselves “If the British can do it, we can do it too!”, as the National Electronics and Computer Technology Center (NECTEC) part of Thailand’s Ministry of Science and Technology designed KidBright32 board and courses to teach STEM to Thai students. The board is based on Espressif Systems ESP32-WROOM-32 WiFI and Bluetooth module, and comes with large holes for power (5V/GND) and 6 digital inputs/outputs,  smaller through holes for I2C and more I/Os, as well as an I2C header. We’ll also find some LEDs, two dot matrix LED displays, three buttons, a buzzer, an RTC, a light …

Vivo Announces TOF 3D Sensing Technology with 300,000 Sensor Points

Vivo TOF 3D Sensing Technology

Earlier this year, I reviewed a TOF sensor board based on STMicro VL52L0X Time-of-Flight ranging sensor that allows to measure distance accurately up to 2 meter using a 940 nm laser and a detection array with a few points to measure the time it takes for the light to travel and determine the distance. VIVO has showcased a smartphone solution leveraging time-of-flight technology at Mobile World Congress Shanghai 2018, but instead of using it for 2D measurements with a small detection array, their TOF 3D Sensing Technology creates 3D scans of objects using a whopping 300,000 sensor points. The technology will enable features & applications such as facial, gesture and motion recognition, 3D photography and extended/augmented reality. Vivo’s TOF 3D Sensing solution is said to deliver 10 times more depth of information than existing Structured Light Technology, for example used for FaceID in the latest iPhones. Vivo’s technology allows 3D mapping at up to three meters from the phone, and …
