## Notes
|
|
|
|
### WiFi
|
|
|
|
By default, upon boot the LoPy4 will create a WiFi access point with the SSID `lopy4-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`, for this reason using `P12` should be avoided unless WiFi is disabled in your application.
|
|
|
|
### Power
|
|
|
|
The `Vin` pin on the LoPy4 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 LoPy4, otherwise the on-board regulator will be damaged.
