PWR_EN Option
PWR_EN installed on both pins will power the module from the battery. Always idle the
PWR_EN option when the module is not being applied or unnecessary battery life loss
will occur. Always open PWR_EN when connecting the J1 development port. For best
operation of the module with development port application is to provide 3.3V via the
BDM connection (PWR_EN OPEN).

J1 Connector – Development Access Port
J1 provides BDM connection to the HCS08 microcontroller in the MXYP8300 device.
An adapter cable is provided in the demonstration kit to allow a standard BDM cable to
be applied.

Battery
The battery is a lithium coin cell type, model CR2325 or same. If the module does not
operate, the battery voltage should be measured with a suitable voltmeter and replaced
if the voltage is at or below 2.7V. W
