![](https://3086745545-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LIL0iGdl11z7Jos_jpX%2F-LKN7scqKKkb6TqB3uYO%2F-LKN86Uvh5ocb97lAaOu%2Fl01-reference.png?generation=1534782118381233\&alt=media)

The L01 OEM reference board is a reference design suitable L01 as well as W01 making it possible to have a single PCB design that can accommodate both OEM modules.

{% hint style="info" %}
If you require a reference board for the L04 or G01, this design is **not** suitable as it does not feature a SIM slot or the double antenna connection. For the G01 or L04 please use the [Universal OEM Baseboard Reference](/product-info-datasheets/oem/universal_reference.md)
{% endhint %}

## Features

* Suits both L01 or W01 OEM Modules
* U.FL connector for the L01's LoRa output.
* On-board 2.4GHz antenna for WiFi and Bluetooth, with the ability to switch

  to a external antenna via a U.FL connector.
* WS2812B RGB LED
* 3.5-5.5 Input switch mode DC-DC regulator with low current draw during deep

  sleep
* Reset button
