The module has two B2B (board-to-board) connectors (JM4 and JM5) with the following features:

• gender: female
• overall number of contacts: 160
• contacts per connector: 80
• rows per connector: 2
• pitch: 1.27 mm = 50 mil = .050"

Trenz Electronic recommends to mate the standard B2B connectors with the following ones:

• 2 x W+P 6110-080-00-10-PPTR 1.27 mm (50 mil = .050") pitch 80-pin double row boxed plug (male) header board-to-board (B2B) connectors.

Figure 16: Close-up of the recommended mating B2B connector.
This connector couple offers the following two advantages:

• the module is protected against polarity inversion;
• the connection presents a mechanical resistance sufficient for most applications.

Ordering codes for connectors JM4 / JM5 and their mating connectors are given in Table 2.

Table 2: Ordering codes of recommended B2B connectors.
The mating height of connectors 6060-080-46-00-10-10-PPTR and 6110-080-00-10-PPTR is 6mm.
Connectors JM4 and JM5 can mate also with any 1.27 mm (50 mil = .050") pitch male header connectors with up to 2 × 40 pins. Figure 17.
