Transceiver nRF2401A Module Trace Antenna

sku: WRL-00153

Description: Miniature RF (MiRF) 2.4GHz transceiver modules with built in antenna designed around the Nordic Semiconductor nRF2401A with high sensitivity and good range. These units are a SparkFun exclusive; small in stature, big on performance, all wrapped up in a user friendly package. Units come with an empty 0.1" spaced footprint ready for a straight header, right angle header (recommended), or your own wires/umbilical cable.

The following pins are brought out to the header:

• 3.3V VCC / GND
• CE : Chip Enable
• CS : Chip Select
• DR1 : Data Ready
• CLK1 : Clock
• DATA : Data

• Frequency: 2.4~2.524 GHz
• Modulation type: GFSK
• Operating Voltage: 3V
