2.1.2 Pin Description

Notes for Table 2 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 definition of functions in column Function, see Section 2.3 Pin Function Description.

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