Functional Description
• The CYWM6935 LR 2.4-GHz DSSS Radio SoC Module
includes radio (CYWUSB6935) , antenna, and all external components
The CYWM6935 WirelessUSB LR Radio Module offers a
complete radio module solution for integration into existing or
new 2.4-GHz products.
• Complete Radio Module with Dual PCB Trace Antennas
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.
• Operates in the unlicensed Industrial, Scientific, and
Medical (ISM) band (2.4 GHz–2.483 GHz)
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.
• –95-dBm receive sensitivity
• Up to 0-dBm output power
• Range of up to 50 meters or more
3.0
• Data throughput of up to 62.5 kbits/sec
• SPI microcontroller interface (up to 2 MHz data rate)
• Operating voltage from 2.7V to 3.6V
• Small PCBA Design: 0.95” (23.75 mm) by 0.95” (23.75
mm) by 0.212” (5.3 mm) (L x W x H)
• FCC Modular Approval Grant to meet FCC Part 15, EN
300 328-1, EN 301 489-1, and Industry Canada RSS-210
standards
• An FCC Module Approval (MA) Grant provides
customers significant cost savings, by allowing
customers to adopt the CYWM6935 FCC ID into their
own products
