鈥?SPI microcontroller interface (up to 2 MHz data rate)
鈥?Operating voltage from 2.7V to 3.6V
鈥?Small PCBA Design: 0.95鈥?(23.75 mm) by 0.95鈥?(23.75
mm) by 0.212鈥?(5.3 mm) (L x W x H)
鈥?FCC Modular Approval Grant to meet FCC Part 15, EN
300 328-1, EN 301 489-1, and Industry Canada RSS-210
standards
鈥?An FCC Module Approval (MA) Grant provides
customers significant cost savings, by allowing
customers to adopt the CYWM6935 FCC ID into their
own products
The CYWM6935 WirelessUSB LR錚?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 4-1.
