Recommended Target Debug Connectors and Position
The target debug connector is a 10-pin, 1.27mm, double-row connector (e.g. Samtec FTSH-105-01-L-DV,Samtec FTSH-105-01-L-DV-K with Keying Shroud).
1. Use the target debug connector(s) with the Keying Shroud option since incorrect connection can cause damage to the hardware.
2. Pin 1 of the connector(s) should be located toward the PCB’s edge to prevent the need to twist or fold the debug ribbon cable(s) (see the picture below).
3. When using DAP and the DAPE debug interfaces, the DAPE connector should be placed to the left of the DAP connector when looking from the edge of the PCB. The connectors must be at least 11.0 mm apart, although a distance of 16.8 mm is recommended. The goal should be to link the Active Probe to the target hardware via non-twisted and, when DAPE is used, parallel ribbon cables.
