5. Male Headers: Break the male header row into 2 sections: one 4-pin section and one 5-pin
section. These male headers on the expression board get plugged into the female headers on the
main board, so we will use the female headers as a jig to help us install the male headers. Back

headers onto the main board correctly, the expression board should set onto these male headers
easily. Solder the male headers to the expression board (126).
