WirelessUSB LSTM Radio Module
1.0 Features 2.0 Functional Description
* The CYWM6934 LSTM 2.4-GHz DSSS Radio SoC Module includes radio (CYWUSB6934), antenna, and all external components * Complete Radio Module with PCB Trace Antenna * Operates in the unlicensed Industrial, Scientific, and Medical (ISM) band (2.4 GHz-2.483 GHz) * -90-dBm receive sensitivity * Up to 0-dBm output power * Range of up to 10 meters or more * 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: 0.975" (24.38 mm) by 0.65" (16.25 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 CYWM6934 FCC ID into their own products The CYWM6934 WirelessUSB LS Radio Module offers a complete radio module solution for integration into existing or new 2.4-GHz products. The CYWM6934 is tested for functional operation and is FCC/ETSI(EU)/Industry pre-certified. The module is supplied with an integrated PCB trace antenna. The CYWM6934 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.
