### BiBoard V1 USB Driver to access the serial port

{% hint style="warning" %}
Some USB cables are just for charging and do not have data transfer capability. Using the original data cable in the kit is better for making the uploading successful. &#x20;
{% endhint %}

When you use a USB type-C data cable to upload the firmware for the **mainboard.**

* In Windows, if there is **no** serial port in the port list of **Device Manager**:

<figure><img src="https://1565080149-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MQ6a951Q6Jn1Zzt5Ajr-887967055%2Fuploads%2FpdmsRGnMjMLkcAtJv58i%2Fimage.png?alt=media&#x26;token=ad20dccf-16ff-414f-a208-c66728587869" alt=""><figcaption></figcaption></figure>

* In Mac, open the **Terminal** program under the **Applications**-**Utilities** folder and type the following commands. If no serial device name starting with "***tty.wchusbserial***" or "***cu.wchusbserial***" is found:

  <pre><code>cd /dev
  <strong>ls
  </strong></code></pre>

#### Please download and install the USB driver:

* Windows: <https://www.wch-ic.com/downloads/CH343SER_EXE.html>
