3. Connectors

This section summarizes the types of connectors used in foxBMS 2.

This section of the documentation is not yet complete.

3.1. Convention for Molex Micro-Fit 3.0 Connector Pin Numbering

Fig. 3.3 presents the convention for the numbering of pins in Molex connectors. This type of connector is the main type of connector that is used for foxBMS 2. The numbering style is used throughout this documentation.

Description of pin numbering in Molex connectors.

Fig. 3.3 Supply connector pin out, receptacle - rear view, header - front view (image source: MOLEX)

There are two types of connectors:

  • Header

  • Receptacle, plugged into the header

The numbering shown on the left in Fig. 3.3 is always valid when viewing in the direction indicated by the arrow with the indication viewing direction. This must be taken into account when crimping the receptacles.

3.2. Convention for Samtec Edge Rate connectors

3.3. Convention for Mictor Pin Numbering

3.4. Convention for Wuerth WR-MJ connector

3.5. Debug adapters

The foxBMS BMS-Master is connected to the debugger through a debug port. On the standard design, a Mictor 38 pin connector is used with the pin numbering described in Convention for Mictor Pin Numbering.

The benefit of this connector is that it enables both a JTAG connection (for debugging purposes) and a trace connection (for detailed trace analysis). An adapter is needed to interface this port to a debugger. Examples are - Converter IDC20A to Mictor-38 from Lauterbach (part number LA-3722) - J-Link Mictor 38 Adapter from Segger (part number 8.06.08) - TI-CTI-20 Adapter from Segger (part number 8.06.06)
