Connecting to a UPDI Target

The recommended pinout for the 6-pin UPDI connector is shown in
Connection to a 6-pin 100-mil UPDI Header
Use the 6-pin 100-mil tap on the flat cable (included in some kits) to connect to a standard 100-mil UPDI header.
Connection to a 6-pin 50-mil UPDI Header
Use the adapter board (included in some kits) to connect to a standard 50-mil UPDI header.
Connection to a Custom 100-mil Header
The 10-pin mini-squid cable should be used to connect between the Atmel-ICE AVR connector port and the target
board. Three connections are required, as described in the table below.
