{% hint style="info" %}
Please note that the PIN assignments for UART1 (TX1/RX1), SPI (CLK, MOSI, MISO) and I2C (SDA, SCL) are defaults and can be changed in Software.
{% endhint %}

## Differences from WiPy 2.0

* Deep sleep current draw fixed, now only 19.7µA
* Upgraded RAM from 512KB to 4MB
* Upgraded External FLASH from 4MB to 8MB
* Antenna select pin moved from GPIO16 to GPIO21 (P12)

## Datasheet

## Notes

### WiFi

By default, upon boot the WiPy3 will create a WiFi access point with the SSID `wipy-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 WiPy3 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 WiPy3, otherwise the on-board regulator will be damaged.
