It is really easy to implement your wireless control transmitter application with the SmartLEWIS™ MCU family. This simple kit contains everything you need and it takes just a few steps: Plug the RF transmitter board into a USB port on your PC Install the software (SW) development environment from KEIL Insert some lines of C code representing your application into the prepared application framework. Powerful library functions keep your code simple as there is no need to step down to the bits and bytes on the hardware level Compile the source code and download it to the USB RF stick Disconnect from the PC and enjoy your application; power will be supplied by the stick’s internal rechargeable battery Key features of the RF Transmitter USB stick: PMA7110 multiband ASK/FSK RF-transmitter chip with integrated 8051 microcontroller RF-matching network for 50-Ohm SMA connector (5dBm, 8dBm or 10dBm output levels available) Rechargeable Li-ion battery for autonomous operation after disconnecting from USB port USB interface with hot-plug capability (based on FT2232) SW application download to PMA-Flash SW debugging Power supply and battery charging 4 status LEDs, 2 user LEDs indicating transmission activity and battery status 4 general-purpose I/Os available on connector for external push buttons, LEDs, or digital sensors
