Wireless modules
Hernan Alcerreca
Nordic Semiconductor ASA announced that designers without specialist RF knowledge can now build an Ultra-Low Power (ULP) ISM-band wireless link into a product or application within hours by using pre-approved modules developed by US RF specialist, RF Digital. Because all the RF development work has been done, the modules only require a digital In/Out, power (+V) and ground (GND) connection, the company said.
The modules are designed to work in almost any operating environment or product design with the exception of sealed metal enclosures which the laws of physics dictate will act as an electromagnetic shield to RF.
Seven radio-only modules based on the following existing Nordic transceivers are being offered: the Nordic Semiconductor 2.4GHz nRF24L01 (RF Digital Modules RFD21010, RFD21676, RFD21677), nRF2401 (RFD21006), and nRF24E1 (RFD21018); plus the 433/868/915MHz nRF905 (RFD21002), and nRF9E5 (RFD21014). The modules based on the Nordic “E” transceivers (nRF24E1 and nRF9E5) also include on-board EEPROMs.
