[Ampseal application specification (instruction manual)](https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Specification+Or+Standard%7F114-16016%7FM%7Fpdf%7FEnglish%7FENG_SS_114-16016_M.pdf%7FN-A): This document includes how to crimp connectors, how to install them in to headers, and how to remove pins from a header.
Most boards will need a debug header installed if you want to attach a debugger (not used for normal users). The recommended connector is Samtec PN `FTSH-105-01-F-DV-007-K`. When soldering the connector, the keying notch goes towards the center of the board, nearer to the 23p center connector.
Any debugger compatible with the standard 10-pin Cortex Debug Header should work, though the [STLINK-V3 Mini](https://www.st.com/en/development-tools/stlink-v3mini.html) is recommmended. It's available for $10-12 US from normal distributors like Mouser/Digikey. A ribbon cable is included so the connector and programmer are all that's required to debug on Proteus.
