Nordic Transceiver nRF2401A Module Trace Antenna

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
