6.16 Pmod™ connector
6.16.1 Description
The CN4 Pmod
™
standard connector is in the STM32L562E-DK board to support flexibility in small form factor
application. The Pmod
™
connector implements the Pmod
™
type 2A and 4A on the STM32L562E-DK board.
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
™
module.
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
™
connector.
Table 28 describes the I/O configuration to select the SPI, the UART or the mikroBUS™ interface on PMO
connector.
