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"

Board to board connector assembled on the TE0320.

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.

 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 the table below.

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.

Hardware Design Requirement

PUDC_B (pull-up during configuration, active Low) pin in TE0320 modules is hard-wired high, determining user-I/O pins to float before and during configuration. Turning off pull-up resistors in hot-swap or hot-insertion applications, disables potential current paths to the I/O power rail. However, external pull-up or pull-down resistors may be required on each individual I/O pin depending on the specific application.
