• Manufacturer Part Number: nRF903
• Description: Multichannel RF Transceiver 433/868/915MHz
• Manufacturer: Nordic VLSI

PRODUCT SPECIFICATION
A pre-programmed channel (868.1856MHz) is available without using the SPI-
configuration procedure. While in test mode (ref. Table 8.), the 868.1856MHz
channel is activated with maximum power setting and an output clock frequency of
1.3824MHz. This feature has been included to ease debugging of micro-controller
software and to allow measurements of RF-performance without use of SPI
configuration software.
