## Notes
|
|
|
|
### WiFi
|
|
|
|
By default, upon booting up the GPy will create a WiFi access point with the SSID `gpy-wlan-XXXX`, where `XXXX` is a random 4-digit number, and the password `www.pycom.io`.
|
|
|
|
The RF switch that selects between the on-board and external antenna is connected to `P12`, so for this reason using `P12` should be avoided unless WiFi is disabled in your application.
|
|
|
|
### Power
|
|
|
|
The `Vin` pin on the GPy can be supplied with a voltage ranging from `3.5v` to `5.5v`. The `3.3v` pin on the other hand is output **only**, and must not be used to feed power into the GPy, otherwise the on-board regulator will be damaged.
|
|
|
|
### AT Commands
|
|
|
|
The AT commands for the Sequans Monarch modem on the GPy are available in a PDF file.
