The MAX7037 evaluation kit (EV kit) is a fully assembled and tested PCB to evaluate the MAX7037 sub-1GHz, Ultra-Low-Power, RF ISM transceiver. The EV kit is connected to the PC through a Siam Kitty board. The EV kit gets power from the Siam Kitty board and runs from a minimum supply voltage of only 2.1V.
A particular EV kit will only work at a specific carrier frequency. The frequencies supported are: 315MHz, 434MHz, 868MHz, 902MHz, 915MHz, and 928MHz. EV kits are shipped configured for 315MHz operation. It is necessary to change the RF matching components to configure an EV kit to work at one of the other frequencies. Further details are provided in the Changing EV Kit for Operation at Other Frequencies section.
Note that, if an EV kit is used at a frequency other than that for which it is configured, it will likely either not work at all or display very poor performance. Ensure that both EV kits match the frequency for which they are configured.
