USB Serial Adaptor - with either micro USB or USB-C connector.

Plugs directly onto 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 on a Raspberry Pi and for Arduino programming (using RTS for reset).

We use through hole connections on both micro USB and female 6 way 0.1" header for a more robust product over the surface mount alone.

Pinout	Description
RTS	Request to send
RX	Receive (connect to remote TX)
TX	Transmit (connect to remote RX)
3V	3.3V supply (50mA max)
CTS	Clear to send
GND	Ground

The following baud rates are supported

Baud rate	Miss rate (%)
2,400	0.16
4,800	0.16
9,600	0.04
19,200	0.04
38,400	0.16
57,600	0.16
115,200	0.16
230,400	0.16
460,800	0.79
1,700,000	0.84
2,300,000	0.62
3,400,000	0.84

This board can only be used with systems using 3.3 volts, connecting to those using higher/lower voltages may result in damage.

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

The IC is 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.

Thanks for the product.
it is perfectly executed. And the shipping was really fast.
