Cellular antenna working inside all-metal case

Capacitive-feed antenna that can be enclosed in an all-metal mobile handset case People that know and follow me a longer period already note that I am reading and collecting anything about embedded cellular antennas that looks unique.  My hard disk is full with files about special small embedded antennas. Today I make a text public […]

M2M module: Embedded Linux, ARM9, GPRS module, USB and further Interfaces

Today I would like to show and to talk about a new Linux based application for wireless M2M. The PCB is already in use in several projects. Based on its enclosure it can be used as a final product for end users. It supports a lot of interfaces like SD card / MMC card, GPIO Pins , AD / DA converter, UARTs, USB Device, USB Host, I2C, SPI and JTAG. At GPIO you will find PMW (Pulse Wide Modulation), counters and other intelligent channels.

Arduino with GSM GPRS GPS Shield

… the extension module for GSM / GPRS and GPS

The open-source physical computing platform Arduino, based on easily applicable hardware and software for the development of prototypes, consists of a micro controller
(ATmega328) with numerous digital as well as analogue inputs and outputs and interfaces…
Arduino boards can be expanded to valuable features by plugging the so-called ”Shields”. With the GSM / GPRS/ GPS-Shield the Arduino board is enabled to use GSM (mobile communication) and GPS functionality (navigation), for example

Navigation without GPS? Sensors with Greenfield app in cellphones could replace the need of GPS

Team of researchers at Microsoft has taken up the task of giving you a perfect solution in the situations where GPS refuses to work. A prototype device called Menlo phone will collect the data with the help of the sensors, as the user walks indoors or in the places where GPS’s signals are weak.

Reference design for RFID temperature data logger

With  a data logger reference design based on the 64-Kbit Dual Interface EEPROM (M24LR64), a low power Microcontroller (STM8L101) and a digital temperature sensor (STTS75) you can develop your data logger quick and easy. It measures temperature, and offers an RF access to the data of the application thanks to the ISO15693 interface of the […]

Can you believe? RFID tranponder, EEPROM, temperature sensor, RTC, digital logic- all in one chip

This chip is real amazing, because it is all in one.  You just need an RFID antenna, what could be a PCB track and a battery. The rest will be done by the logic inside. If temperature logging is not enough, then you can add external sensors  interface. Right now there is a humunity sensor […]

Is this an EEPROM with RFID transponder or a RFID transponder with EEPROM?

The M24LR64 is an electrically-erasable memory (EEPROM) that can also be programmed wirelessly by industry standard RFID (radio-frequency ID) equipment. Using the M24LR64 for program or data storage provides extra flexibility for customers, allowing software updates or specific parameters to be applied in the supply chain. With an easy implementation based on two industry standard […]
