Samsung S-Patch3 Wearable Health Tracker Based on Samsung Bio-Processor Hits the FCC

At the end of 2015, Samsung unveiled their S3FBP5A Bio-Processor comprised of an ARM Cortex-M4 MCU, a DSP, and sensors for PPG, ECG (electrocardiography), Skin temperature, BIA, and GSR to have a single package to design tracker able to monitor your health condition. The company demonstrated an early prototype called S-Patch at CES 2016 (See embedded video at the end of this post), and now S-Patch3 wearable health monitoring system has just hit the FCC. The system has two round shapes case connected via a cable, with one for the battery compartment, and the other containing the Bio Processors, and meant to be placed on your chest. The device can then synchronize the data with your smartphone in real-time over Bluetooth. People with heart conditions may benefit from the system, as if they wish to do so, they could share the data with their doctor. Few documents are publicly available […]

Nordic Thingy:52 Bluetooth 5 IoT Sensor Development Kit Targets Mobile & Web App Developers

Some developers may be interested in providing solutions for the Internet of Things, but they may not have the skills or interest in making their own hardware, and/or develop firmware, and just want to create demos or prototypes quickly, focusing on app development instead. Nordic Semiconductors has recently launched Thingy:52 IoT Sensor Kit with Bluetooth 5 & NFC connectivity, and various sensors for those developers. Nordic:52 IoT Sensor development kit (nRF6936) hardware specifications: MCU – Nordic Semi nRF52832 ARM Cortex-M4F Bluetooth 5 System on Chip (SoC) Connectivity – Bluetooth 5 LE and NFC Sensors Temperature,Humidity, Air pressure, Air quality (CO2 and TVOC), color and light intensity 9-axis motion sensing – Tap detection, orientation, step counter, quaternions, euler angles, rotation matrix, gravity vector, compass heading, raw  accelerometer, gyroscope, and compass data Audio Speaker for playing prestored samples, tones, or sound streamed over BLE (8-bit 8 kHz LoFi) Microphone streaming (ADPCM compressed […]

OpenH PULSAR and QUASAR Boards Add 4G LTE Cat M1, or Cat 4/1 to Raspberry Pi Boards

We’ve seen a bunch of IoT boards with 2G connectivity recently including Orange Pi 2G-IoT, Wio GPS, and Nadhat, but while in some countries 2G will still work for many years, those boards are already obsolete – or soon will be – in many other countries. However, finding low cost 3G / 4G  boards is more difficult, and while one solution is to use 3G or 4G USB dongles,  “OpenH – Open Hardware” – part of KLiP Industries – has designed two boards with 4G connectivity provided by Quectel modules. OpenH PULSAR Board PULSAR board is compatible with Arduino Zero and features the following specifications: MCU – Atmel/Microchip SAMD21 ARM Cortex M0+ MCU (the as the one used in Arduino Zero) Connectivity 4G LTE  Cat M1 modem with GPS (Quectel BG96-NA); No external antennas required Bluetooth and NFC Security – Dedicated management CPU with crypto engine Power Supply 10W digital power supply and battery charger with direct solar input FCC […]

Smartwatch for the Blind – Dot Watch Supports Braille Language, Sync Data over Bluetooth

A South Korean company has created Dot smartwatch specifically designed for the blinds and visually impaired, as it supports Braille language through 24 dots that move up or down depending on the data to show. Like other smartwatches, it will also pair with a smartphone, and received notifications over Bluetooth to Android and iOS smartphones. Dot watch specifications: Wireless MCU – 32-bit ARM Cortex M4F + Cortex M0 microcontroller “Display” – 4 Dot Cells (24 Dots) made of 6000 series silver aluminum Connectivity – Bluetooth LE 4.2 Misc – 24 touch sensors, shaft horizontal vibration motor, a crown, two buttons Battery – 400mAh li-polymer battery good for a typical 7 days on a charge Dimensions – Watch: 43mm x 12.5mm; Leather band – S size: 22x220mm; M size: 22x250mm; L size: 22x290mm Weight – 27g This is all made possible through the company’s dot rotor technology that allows to move […]

Getting Started with ESP32-Bit Module and ESP32-T Development Board using Arduino core for ESP32

Espressif ESP32 may have launched last year, but prices have only dropped to attractive levels very recently, and Espressif has recently released released ESP-IDF 2.0 SDK with various improvements, so the platform has become  much more interesting than just a few weeks ago. ICStation also sent me ESP32-T development board with ESP32-bit module, so I’ll first see what I got, before trying out Arduino for ESP32 on the board. ESP32-T development board with ESP-bit Module – Unboxing & Soldering One thing I missed when I asked for the board is that it was not soldered, and it comes in kit with ESP32-bit module in one package, and ESP32-T breakout board with headers in another package. The 21.5x15mm module is based on ESP32-DOWNQ6 processor with 32 Mbit (4MB) of flash, a chip antenna, and a u.FL connector. The module is apparently made by eBox, and also used in Widora board with […]

Whitecat ESP32 N1 Board Combines ESP32 WiFi + Bluetooth SoC with a LoRa Transceiver, Runs Lua RTOS

Espressif ESP32 SoC is gaining traction right now as prices have come down, and there’s still an on-going fight among LPWAN standards with LoRaWAN being fairly popular in Europe. Whitecat, a group of engineers from several companies based in Citilab, Barcelona, Spain, has designed a board that combines both ESP32 and a LoRA transceiver, bringing an alternative to Pycom LoPy board, but instead of running MicroPython, they have developed Lua-RTOS. Whitecat ESP32 N1 hardware specifications: SoC – Espressif ESP32 dual-core Tensilica LX6 microprocessor @ up to 240MHz with 520kB internal SRAM Storage – 4MB flash memory Connectivity LoRa WAN transceiver working in the 868 (EU) MHz / 915 (USA) MHz with on-board antenna, and u.FL connector for external antenna Integrated 802.11b/g/n WiFi transceiver with on-board antenna, and u.FL connector for external antenna Integrated dual-mode Bluetooth (classic and BLE) I/O Headers – 2x 16-pin with SPI, I2C, I2S, SDIO, UART, CAN, […]
