Pmod - Renesas RX100 Series User Manual

Renesas Starter Kit for RX140

5.6 Pmod™

The RSK board is equipped with connectors for Digilent Pmod™ interface. Please connect the provided LCD
module to the PMOD1 connector.
Care should be taken when installing the LCD module to ensure pins are not bent or damaged. The LCD module is
vulnerable to electrostatic discharge (ESD); therefore appropriate ESD protection should be used.
Figure 5-1 below shows Digilent Pmod™ Compatible Header Pin Numbering. Connection information for the
Digilent Pmod™ Compatible header is provided in Table 5-4 and Table 5-5 below.
Please note that the connector numbering adheres to the Digilent Pmod™ standard and is different from all
other connectors on the RSK designs. Details can be found in the Digilent Pmod™ Interface Specification.
