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 […]

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 […]

Bluetooth low energy is an “always off” technology. Basically it stays in the lowest power modes

Because power consumption is so low, coin cells will typically last a year or more. Bluetooth low energy chips can operate either as slaves or masters and which device takes what role is decided during the initial negotiation. There is no reason for a tag to be the proverbial one-trick pony. Design cycles will be short compared to proprietary solutions because the design team can concentrate its efforts on writing application layer code instead of the entire protocol stack. Sensing a means of making mobile phones even more indispensable, Nokia and other manufacturers are clearly on the Bluetooth low energy bandwagon. “We see it as part of the continued evolution to the Bluetooth chip set,” says Mika Sarén, Nokia’s Senior Technology Manager for Connectivity. When the specification is released, it will be supported in time for the first product release on Forum Nokia, the company’s web site for developers.

Is RFDP8 better than BlueTooth, ZigBee, WLAN and other protocols?

RF Digitals RFDP8 proprietary patent-pending frequency agility protocol operates in the internationally accepted 2.4 GHz band. The RFDP8s leading-edge advanced algorithm is not burdened by a heavy-weight stack as is BlueTooth, ZigBee, WLAN and other protocols, which are well suited for cross-manufacturer interoperability. The RFDP8 protocol is highly robust and effective where there is a […]

Unlimited number of nodes with and without network mode

A picture tells more than thousand words: • 16 bit CRC data accuracy verification built-in • 32 bit unique factory ESN in every module (4 billion combination security) • Flexible network modes, including broadcast and individual addressing • Switch on/off, logic, remote-control without the need for an external controller • Switch nodes individually addressable without […]

Beagle Board with UMTS / 3G modem extension

The goal of the Wild ducks project is to run Symbian on off-the-shelf hardware. This page describes the hardware side of the project. All the large pieces can be bought online on a fairly small budget. We had to build a few cables ourselves to fit the pieces together. This will be described in detail.
