1. Enable on-board JTAG functionality by setting JP8 according to :doc:`../../get-started/get-started-wrover-kit`, section :ref:`get-started-esp-wrover-kit-setup-options`.
2. Verify if ESP32 pins used for JTAG communication are not connected to some other h/w that may disturb JTAG operation:
Most of the pins on the ESP-WROOM-32 are broken out to the pin headers on the board. Users can program ESP32 to enable multiple functions such as PWM,ADC, DAC, I2C, I2S, SPI, etc.
There following options are available to provide power supply to the ESP32-PICO-KIT V4:
1. Micro USB port, this is default power supply connection
2. 5V / GND header pins
3. 3V3 / GND header pins
..warning::
Above options are mutually exclusive, i.e. the power supply may be provided using only one of the above options. Attempt to power the board using more than one connection at a time may damage the board and/or the power supply source.

USB interface. It functions as the power supply for the board and the communication interface between PC and ESP32 module.
Power Select
Power supply selection interface: the ESP-WROVER-KIT can be powered through the USB interface or the 5V Input interface. The user can select the power supply with a jumper. More details can be found in section :ref:`esp-wrover-kit-setup-options`, jumper header JP7.

Several pins / terminals of ESP32 module are allocated to the on board hardware. Some of them, like GPIO0 or GPIO2, have multiple functions. If certain hardware is not installed, e.g. nothing is plugged in to the Camera / JP4 header, then selected GPIOs may be used for other purposes.
Main I/O Connector / JP1

The JP1 connector is shown in two columns in the middle under "I/O" headers. The two columns "Shared With" outside, describe where else on the board certain GPIO is used.

..note::
As GPIO32 and GPIO33 are connected to the oscillator, to maintain signal integrity, they are not connected to JP1 I/O expansion connector. This allocation may be changed from oscillator to JP1 by desoldering 0R resistors from positions R11 / R23 and installing them in positions R12 / R24.
Small and convenient development board with ESP-WROOM-32 module installed, break out pin headers and minimum additional components. Includes USB to serial programming interface, that also provides power supply for the board. Has press buttons to reset the board and put it in upload mode.
