Wiring & Setup
Important: This module operates at 3.3V logic. Do not connect directly to 5V systems.
Connections:
-
VCC → 3.3V regulated supply
-
GND → Ground
-
CE → Any configurable digital pin
-
CSN / CS → SPI chip-select pin
-
SCK → SPI clock
-
MOSI → SPI data (MCU to module)
-
MISO → SPI data (module to MCU)
-
IRQ → Optional interrupt pin
For 5V microcontrollers (e.g., Arduino UNO, Mega), use a 3.3V regulator (such as AMS1117-3.3) and level shifters on SPI lines.
Installation Notes
-
Use a stable 3.3V power source
-
Position the SMA antenna vertically and in open air for optimal range
-
Avoid enclosing the antenna in metal housings to maintain signal quality

Arrived very quickly and worked a treat.
This product is most likely. Compact and easy, daily use. 😉
Very good repair set at an excellent price! Arrived on time and came well-packed. Very pleased with it. Recommended seller.
Nice doing business, product was as described in description. Works as Indented, thanks.
For use at my soldering station to keep fumes out of my eyes
