Figure 3: Pin Layout of ESP32WROOM32E (Top View)
Note:
• The pin layout of ESP32-WROOM-32UE is the same as that of ESP32-WROOM-32E, except that ESP32-WROOM-
32UE has no keepout zone.
• The pin diagram shows the approximate location of pins on the module. For the actual mechanical diagram, please
refer to Section 7.1 Physical Dimensions.
3.2 Pin Description
The module has 38 pins. See pin definitions in Table 2.
