1. WFM200 Pinout
WFM200 is a 6.5 x 6.5 mm LGA module. The diagram below describes the pinout (top view).
Figure 1.1. WFM200 Pinout
Table 1.1. WFM200 Pin Description
Pin # WFM200 Pin Name Description
1 GND
2
2G4ANT_IN, or No Connect on OPN
with no integral antenna
Embedded 2.4 GHz antenna port. To use the antenna, connect this pin to
RF_1.
3 RF_1
50 Ω RF_1 input/output port. If not used, this pin should be connected to
GND through a 50 Ω resistor.
4, 5, 6, 7, 8 GND
9 RF_2
50 Ω RF_2 input/output port. If not used, this pin should be connected to
GND through a 50 Ω resistor.
10 VDD_PA Power supply for the power amplifier.
11 GND
12 RESETn RESET pin, active Low.
13 GPIO/WUP This pin can be used to wake-up the device from sleep mode or as a GPIO.
14 GPIO/PTA_TX_CONF
As part of PTA interface, these pins can be used to manage co-existence
with another 2.4 GHz radio or can be used as a GPIO.
15 GPIO/PTA_RF_ACT
16 GPIO/PTA_STATUS
17 GPIO/PTA_FREQ
