Description

™
The Pmod standard connector (CN4) is in the STM32L562E-DK board to support flexibility in small form factor
applications. 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
connector.
