: If you still experience poor range even with the YL105, ensure your antennas are not obstructed and that you are using a High PSRR Regulator setup if the environment is electrically noisy.
When comparing the YL105 adapter to a direct connection, the advantages are clear: : Standard Arduino pins often provide only . The YL105 leverages the rail to provide up to
: If the red Power LED is not lit, verify that your input voltage is at least
