| - | | EN Ext | Singal provided to enable an external voltage regulator, if one is being used. This would allow the sketch running on the Wi-FIRE to turn on/off the external voltage regulator. When used with an external voltage regulator, this allows the board to go into an extremely low power operating mode. This signal is connected to Port D, bit 13 (RD13) on the PIC32 microntroller. This is accesible using digital pin 40. | | + | | EN Ext |
