Block Diagram
The block diagram below shows the components of ESP32-5-DevKitC-1 and their interconnections.
Power Supply Options
There are three mutually exclusive ways to provide power to the board:
• USB Type-C to UART port and ESP32-C5 USB Type-C port (either one or both), default power supply
(recommended)
• 5V and GND pin headers
• 3V3 and GND pin headers
Current Measurement
The J5 headers on ESP32-C5-DevKitC-1 (see J5 in Figure
the current drawn by the ESP32-C5-WROOM-1 module:
• Remove the jumper: Power supply between the module and peripherals on the board is cut off. To measure
the module's current, connect the board with an ammeter via J5 headers.
• Apply the jumper (factory default): Restore the board's normal functionality.
Note: When using 3V3 and GND pin headers to power the board, please remove the J5 jumper, and connect an
ammeter in series between the external power supply and the 3V3 pin header to measure the module's current. This
is because the 3V3 pin header supplies power directly to the module, bypassing the J5 headers. Removing the J5
jumper disconnects unnecessary circuits, allowing for a more accurate measurement of the module's current.
Header Block
The two tables below provide the Name and Function of the pin headers on both sides of the board (J1 and J3). The
pin header names are shown in Figure
