USB-C CDC Serial Adaptor (3.3V)

This is the new version of 8086's original 3.3V CDC serial adapter - upgraded to USB-C because USB-C is the FUTURE!

This is a 3.3V USB Serial Adaptor. It plugs directly into our Cluster HAT and MMC (SD) HAT to provide serial console access to the Raspberry Pi for quick access.

Using jumper wires it can be used to access the serial connection on a Raspberry Pi and for Arduino programming (using RTS for reset).

This module can only be used with systems using 3.3V, connecting to those using higher/lower voltages may result in damage. Click here for a 5V version.

The IC used in the adapter enumerates as a Communication Device Class (CDC) device which modern (Win10/Linux/Mac OS X) operating systems have built-in drivers for.

A USB-C cable will be required (not included).

Enabling Serial Console (Raspberry Pi)

To enable serial console on a default Raspberry Pi OS (or Cluster HAT) installation add "enable_uart=1" to your config.txt in the boot partition.
