Reference Designs Create Low-Power Wireless Modules
Providing engineers the ability to create Ultra-Low Power (ULP) ISM-band button-cell powered wireless links, a family of reference designs using Nordic Semiconductor RF tranceiver chips require only a digital In/Out, power (+V) and ground (GND) connection for implementation. The seven module designs are based on the 2.4 GHz nRF24L01 (RF Digital Modules RFD21010, RFD21676, RFD21677), nRF2401 (RFD21006), and nRF24E1 (RFD21018) and 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. The reference designs are fully integrated and comprise a Nordic transceiver, all supporting RF passive and active components, on-board chip antenna, plus pre-loaded, factory tested protocol code.
