Jst Ph - Sensors And Rs485 - REV Robotics Expansion Hub Manual

1.4.3 JST PH – Sen so rs an d RS485
The JST PH style connector is used for motor encoder, analog, digital, I2C, RS485, and UART connections on the
Expansion Hub. These are all 4-pin connections except for the RS485 and UART which are 3 pin. The connectors are
keyed (they only insert in one orientation) and are friction locking. In Figure 2 the keying feature aligned with the cable is
shown.
REV Robotics recommends in most cases that teams use pre-made cables because the quality of the crimp is better
when made using industrial tooling. These cables can be bought directly from the REV Robotics Website (Table 4 and
Table 5) or through other online vendors.
