SparkFun Transceiver Breakout - n with RP-SMA antenna (WRL-
00705)
If you need more range in your wireless connection or if you need to move
your antenna outside an interference zone, we recommend the RP-SMA
antenna version of the breakout. You can learn more about SMA
connectors here. This version works with the RP-SMA 2.4GHz antenna and
its larger counterpart. Because of the external antenna on this version of
the breakout, it has a greater range than the on-board antenna version.
Pins
Broken out pins with labels
While the n IC has 20 pins available, our breakout board
simplifies this down to the 8 pins required to get up and running. These pins
are the same on both versions of the board. The pins function as follows:
•
GND
- Ground
•
IRQ
- Interrupt pin. This pin is active
LOW
.
•
MISO
- 3.3V-5V tolerant SPI slave output.
•
MOSI
- 3.3V-5V tolerant SPI slave input.
•
SCK
- 3.3V-5V tolerant SPI clock.
•
CSN
- 3.3V-5V tolerant SPI chip select.
•
CE
- 3.3V-5V tolerant chip enable. This pin toggles the n
IC between transmit (TX), receive (RX), standby, and power-down
mode.
•
VCC
- This is VRAW and is regulated on-board down to 3.3V for the
proper functionality of the n. Voltage range on this pin is
3.3V-7V
.
