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 […]
Wireless M-Bus Portfolio: Chips, Modules, Terminals, USB-Sticks, Gateways
M-Bus (Meter-Bus) is a European Standard for the remote reading of gas, water or electricity meters. M-Bus is also usable for other types of consumption meters.
The M-Bus interface is made for communication on two wires, making it very cost effective. This protocol exists with several physical layers such as paired wires, optical fibber or radio link. The radio variant of M-Bus is called Wireless M-Bus and is specified in EN 13757-4. It is dedicated to the European ISM frequency band at 868MHz. It means that modules embedding the Wireless M-bus stack must comply with the general SRD standard EN 300-220.

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

Low power network module with IP-addresses
Radio Module that enables secure wireless low power IPv6 communication for sensors and small devices. It utilizes 6loWPAN, the first IETF standard to build wireless, low power IP-based sensor and device networks.
RF as Alternative for Remote Control Applications
Reference Design for RF Remote To ease the process, an RF remote control reference design such as the nRD24H1 is available. The device (transmitter) side of the nRD24H1 is implemented as a hardware module fitted on a six-button remote control application board. The module includes a PCB antenna, a 2.4GHz transceiver (the nRF24L01) and an […]
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 […]
