ANAVI Technology launched several open source hardware boards for the Raspberry Pi and ESP8266 maker communities in the past, starting with RabbitMax Flex home automation HAT for Raspberry Pi, and several others including ANAVI Light Controller ESP8266 board to control LED strips. All boards are designed with KiCad opensource EDA software, and I’ve tested several already such as ANAVI Infrared pHAT or ANAVI Light Controller, and found documentation to be very good and easy to follow. The company has now launched another ESP8266 board with ANAVI Thermometer that allows you to monitor temperature and humidity, effectively acting as a thermostat for home automation. ANAVI Thermometer specifications: SoC – Espressif Systems ESP8266 Tensilica L106 32-bit processor Connectivity – WiFi 802.11 b/g/n Display – Mini OLED display Build-in sensor – AM2302 (DHT22) temperature and humidity sensor Expansion Terminal block for DS18B20 waterproof temperature sensor UART pins 3x slots for I2C sensors Misc – […]
TTGO T-Camera ESP32 Camera Board Comes with OLED Display, Sensors
ESP32 is now being used for AI workloads such as face detection with camera boards like ESP32-CAM, or the upcoming ESP-EYE board from Espressif Systems themselves, combined with ESP-WHO face detection and recognition framework. The two aforementioned board require you to use a phone to vizualize the results, unless you blink some LEDs or connect your own display. But the just released TTGO T-Camera board includes a 128×64 OLED display which should allow you to display face detection and/or recognition results, as well as a BME280 environmental sensor, a PIR sensor, and an optional fisheye lens. TTGO T-Camera board specifications: ESP32-WROVER-B Wireless Module SoC – ESP32 dual core Tensilica LX6 processor Memory – 8MB PSRAM Storage – 4MB SPI flash Connectivity – 2.4 GHz 802.11n WiFi 4, Bluetooth 4.2 LE Camera – 2MP OV2640 camera with normal or fisheye lens Display – 0.96″ 128×64 OLED display connected via SSD1306 I2C […]

Shelly H&T is a Battery Powered ESP8266 WiFi Temperature & Humidity Sensor
WiFi and long battery life do not usually go hand-in-hand, but as we’ve seen recently, companies have managed to design battery powered WiFi cameras that are said to last up to a year on a charge. So for simpler WiFi devices it should be feasible to last over a year, and that’s what “Shelly H&T” – an ESP8266 based battery-powered WiFi temperature and humidity sensor has apparently achieved, with claims of up to 16 months battery life. Shelly H&T specifications: Connectivity – 802.11 b/g/n WiFi (Wifi 4) Sensor – Temperature & humidity Battery – 1x CR123A battery good for up to 16 months Dimensions – 35 mm Ø sphere with flat top/bottom The firmware supports MQTT, and a Rest API, and works with Alexa, Google Home, and home automation suites like OpenHAB, Home Assistant, or Domoticz. The sensor is “open source ready”, meaning you’ll be able to flash your own […]
Sensything ESP32 Board Supports Multi-sensor Data Acquisition, Wi-Fi & Bluetooth (Crowdfunding)
We’ve previously covered to health related boards from Protocentral with HealthPi Raspberry Pi HAT measuring vitals signs, and HeartyPatch open source ECG patch powered by an ESP32 WiSoC. Today, I’ll write about another of their board – Sensything -, not directly related to health applications, but designed for multiple sensor’s analog and digital (I2C, GPIO) data acquisition, and designed around Espressif Systems ESP32 WiFi & Bluetooth SoC. Sensything specifications: SiP- Espressif Systems ESP32-PICO-D4 system-in-package with 4MB Flash, Texas Instruments ADS1220 ADC Wireless Connectivity 2.4 GHz WiFi with on-board PCB antenna, support for Station and Access Point (AP) modes Bluetooth 4.2 / Bluetooth Low Energy (BLE) USB – 1x micro USB port with FT230X (USB-CDC) Expansion I/O: Board-edge alligator clip compatible analog input connectors 2x Sparkfun Qwiic-compatible I2C ports 4x general-purpose I/O pins Analog Input details 4 channels single-ended, 2-channel fully differential Full-scale input range: ± 2.048 V to ± 0.016 […]
GAPUINO GAP8 is a $229 RISC-V MCU Developer Kit for A.I. Applications
GreenWaves GAP8 is a low power RISC-V “MCU class” processor with eight compute cores optimized for artificial intelligence applications, and its main selling point is the ability to do tasks like computer vision or audio processing at very low power, even good enough to run on batteries. When we first covered GAP8 RISC-V processor at the beginning of the year, the company also mentioned a development kit comprised of GAPDUINO Arduino compatible board, a sensor board, and a QVGA camera module to experiment with the solution. The board and development kit are now easier to purchase as the devkit is sold on SeeedStudio for $229. GAPuino board specifications: SoC – GAP8 IoT Application Processor with 8x RISC-V compute cores, 1x RISC-V fabric controller core delivering up to 200 MOPS at 1mW and >8 GOPS at a few tens of mW Memory / Storage – HyperBus combo DRAM/Flash with 512 Mbit […]
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 […]
Vivo Announces TOF 3D Sensing Technology with 300,000 Sensor Points
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 […]
