About
The ExpLoRer is a development/evaluation tool intended for the evaluation of Microchip wireless modules in a research and development laboratory environment. It is not a finished appliance. Manufacturers who integrate ExpLoRer in a finished appliance product must take responsibility to follow regulatory guidelines, for example for CE marking.
