AVRUSBRF01 is based on Atmel AT90USB162 microcontroller, which allows connection to PC through USB, and nRF24L01 transceiver from Nordic VLSI. The kit contains two identical AVR USB RF modules. They can connect to two different USB ports to establish wireless communication and evaluate the solution. They can also communicate with wireless peripherals derived from this reference design. To help with evaluation and development, the modules include two push buttons for hardware reset, in-system programming and extra functions, two LEDs for monitoring activity and a 6-pin header to connect development tools or other peripheral functions. The PCB size is only 3.8x1.6 cm2, which is small enough to be used without change for many applications. If necessary, size can be further reduced by removing the extra features provided for evaluation and development.

Note: the boards may hold 90USBnRF part-number instead of AVRUSBRF01.
