Pin Description

Notes for Table 4 Pin Description:

1. some pin functions are highlighted, specically:

• GPIO – Input only pins, output is not supported due to lack of pull-up/pull-down resistors.

• The highlighted cells indicate pins that are connected to the in-package flash. For details see Section 2.1.3 Pin Mapping Between ESP32-PICO-D4 and

Flash/PSRAM.

• GPIO – have one of the following important functions:

– Strapping pins – need to be at certain logic levels at startup. See Section 3 Boot Configurations.

– JTAG interface – often used for debugging.

– UART interface – often used for debugging.

2. For ESP32-PICO-V3: IO6/IO7/IO8/IO9/IO10/IO11/IO20 belong to VDD_SDIO power domain and can not work when VDD_SDIO power shuts down.

3. For definition of functions in column Function, see Section 2.3 Pin Function Description.

4. Type: I/O — Input/Output; I — Input.
