2.0 Functional Description
The CYWM6935 WirelessUSB LR™ Radio Module offers a
complete radio module solution for integration into existing or
new 2.4-GHz products.
The CYWM6935 is tested for functional operation and is
FCC/ETSI(EU)/Industry pre-certified. The module is supplied
with dual integrated PCB trace antennas.
The CYWM6935 is available in a small PCBA design and can
be mounted horizontally to the device PCB via a 12-pin
header. The pin-out of the header is shown in Figure 5-1.
