Description

The CN4 Pmod
application. The Pmod
6.16.2

Operating voltage

™
The Pmod module is directly supplied by 3.3 V. VDD and VDD_MCU must be set to 3.3 V to be I/O compatible
with the Pmod
6.16.3 Pmod™ interface
A quad SPDT switch driven by two I/Os is used to connect three different interfaces: SPI, UART, and mikroBUS™
interfaces to the Pmod
Table 28 describes the I/O configuration to select the SPI, the UART or the mikroBUS™ interface on PMO
connector.
