Powercast has unveiled its Ubiquity wireless power transmitters, which use radio frequency (RF) power to charge devices over the air.

Measuring just 0.25×0.40 inches, the RCT-xxx-AS transmitter module from Radiotronix targets applications such as remote-keyless-entry units and wireless sensors. Supporting data rates to 4800 bps and ...

Finisar's XFP-RF optical transmitter module is optimal for Dense Wavelength Division Multiplexing (DWDM) applications, which dramatically increase bandwidth over existing fiber infrastructure by ...

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.

The RF803E encoder has three inputs for connection to an array of switches or pushbuttons. Its standard TTL/CMOS output can be connected directly to the data input of an RF transmitter module. When ...

Powercast’s RF power transmitter means to slash RF transmitting technology costs and make convenient, contactless power ubiquitous.

We’ve seen no shortage of projects that use the ESP8266 or ESP32 to add “smart” features to existing home appliances, often by pairing the microcontroller with a radio or IR transmitter. If ...

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals. The ...
