Esp32 Development Board, JTag Function, TFT Display, Camera Support, Esp32- Wrover-B On The Board
➤ 32.768 kHz
An external precision 32.768 kHz crystal oscillator provides a low-power consumption clock used during Deep-Sleep mode.
The FT2232 chip is a multi-protocol USB-to-serial bridge. Users can control and program the FT2232 chip through the USB interface to establish communication with ESP32.
A zero Ohm resistor intended as a placeholder for a current shunt. May be desoldered or replaced with a current shunt to facilitate measurement of current required by ESP32 module depending on power mode.
This version of ESP-WROVER-KIT board has ESP-WROVER-B module installed that integrates 64-Mbit PSRAM for flexible extended storage and data processing capabilities.
➤ Diagnostic LEDs
Four red LEDs connected to GPIO pins of the FT2232 chip. Intended for future use.
Serial port: the serial TX/RX signals on the FT2232HL and the ESP32 are broken out to each side of JP2. By default, the two signals are connected with jumpers. To use the ESP32 module serial interface only, the jumpers may be removed and the module can be connected to another external serial device.
SPI interface used by ESP32 to access flash and PSRAM memories inside the module. Please note that the voltage level on this interface depends on the module used.
Serial port flow control signals: the pins are not connected to the circuitry by default. To enable them, respective pins of JP14 must be shorted with jumpers.
JTAG interface: the JTAG signals on FT2232HL and ESP32 are broken out to the two sides of JP2. By default, the two signals are disconnected. To enable JTAG, shorting jumpers are required on the signals as shown in section Setup Options.
➤ USB Port
USB interface. It functions as the power supply for the board and the communication interface between PC and ESP32 module.
➤ EN Button
Reset button: pressing this button resets the system.
➤ Boot Button
Download button: holding down the Boot button and pressing the EN button initiates the firmware download mode. Then user can download firmware through the serial port.
➤ Power Switch
Power on/off button: toggling to the right powers the board on; toggling to the left powers the board off.
➤ Power Selector
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 Setup Options, jumper header JP7.
➤ 5V Input
The 5V power supply interface is used as a backup power supply in case of full-load operation.
➤ 5V Power On LED
This red LED indicates that a power supply (either from USB or 5V Input) is applied to the board.
NCP1117(1A). 5V-to-3.3V LDO. (There is an alternative pin-compatible LDO — LM317DCY, with an output current of up to 1.5A). NCP1117 can provide a maximum current of 1A. The LDO solutions are available with both fixed output voltage and variable output voltage.
➤ Camera Connector
Camera interface: a standard OV7670 camera module is supported.
➤ RGB LED
Red, green and blue (RGB) light emitting diodes (LEDs), which may be controlled by pulse width modulation (PWM).
➤ I/O Connector
All the pins on the ESP32 module are led out to the pin headers on the ESP-WROVER-KIT. Users can program ESP32 to enable multiple functions such as PWM, ADC, DAC, I2C, I2S, SPI, etc.
➤ Micro SD Card Slot
Develop applications that access Micro SD card for data storage and retrieval.
ESP-WROVER-KIT supports mounting and interfacing a 3.2” SPI (standard 4-wire Serial Peripheral Interface) LCD.
