Hardware Integration Guide
The RESIN_N signal is pulled-up internal to the AirPrime AR7558. An open collector transistor or
equivalent should be used to Ground the signal when necessary to RESET the module.
Note: Use of the RESIN_N signal to RESET the AirPrime AR7558 could result in memory corruption if
used inappropriately. This signal should only be used if the AirPrime AR7558 has become
unresponsive and it is not possible to perform a power cycle.
