For descrip"ons of other versions of the ESP-WROVER-KIT check ESP32 Hardware Reference. If you would like to start using this board right now, go directly to the Start Applica"on Development sec"on. What You Need 1 × ESP-WROVER-KIT V4.1 board 1 x Micro USB 2.0 Cable, Type A to Micro B 1 × PC loaded with Windows, Linux or Mac OS Overview The ESP-WROVER-KIT is a development board built around the ESP32 and produced by Espressif. This board is compa"ble with mul"ple ESP32 modules, including the ESP32-WROOM-32, ESP32-WROVER and ESP32-WROVER-B. The ESP-WROVER-KIT features support for an LCD and a MicroSD card. The I/O pins have been broken out from the ESP32 module for easy extension. The board carries an advanced mul"-protocol USB bridge (the FTDI FT2232HL), enabling developers to use JTAG directly to debug the ESP32 through the USB interface. The development board makes secondary development easy and cost-effec"ve.

ESP-WROVER-KIT block diagram Functional Description The following lists and figures describe the key components, interfaces, and controls of ESP-WROVER-KIT board. 32.768 kHz An external precision 32.768 kHz crystal oscillator provides a low-power consump"on clock used during Deep-Sleep mode. FT2232 The FT2232 chip is a mul"-protocol USB-to-serial bridge. Users can control and program the FT2232 chip through the USB interface to establish communica"on with ESP32. The FT2232 chip also features USB-to-JTAG interface. USB-to-JTAG is available on channel A of the FT2232, whilst USB-to-serial is on channel B. The embedded FT2232 chip is one of the dis"nguishing features of the ESPWROVER-KIT. It enhances users’ convenience in terms of applica"on development and debugging. In addi"on, users need not purchase a JTAG debugger separately, which reduces the development cost, see ESP-WROVERKIT V4.1 schema"c. 0R https://docs.espressif.com/projects/esp-idf/en/latest/get-started/get-started-wrover-kit.html ᒫ 2 ᶭҁ‫ و‬12 ᶭ҂ ESP-WROVER-KIT V4.1 Getting Started Guide — ESP-IDF Programming Guide v3.2-beta1-34-gfb7ba1b documentation 2018/11/7 ӥ‫܌‬5)59 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. ESP32-WROVER 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 capabili"es. The board can accommodate other versions of ESP modules described under WROOM, SOLO and WROVER Modules. ! Note GPIO16 and GPIO17 are used as the CS and clock signal for PSRAM. To ensure reliable performance, the two GPIOs are not broken out. Diagnos!c LEDs Four red LEDs connected to GPIO pins of the FT2232 chip. Intended for future use. UART 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 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. CTS/RTS Serial port flow control signals: the pins are not connected to the circuitry by default. To enable them, respec"ve pins of JP14 must be shorted with jumpers. JTAG 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, shor"ng jumpers are required on the signals as shown in sec"on Setup Op"ons. https://docs.espressif.com/projects/esp-idf/en/latest/get-started/get-started-wrover-kit.html ᒫ 3 ᶭҁ‫ و‬12 ᶭ҂ ESP-WROVER-KIT V4.1 Getting Started Guide — ESP-IDF Programming Guide v3.2-beta1-34-gfb7ba1b documentation 2018/11/7 ӥ‫܌‬5)59 USB Port USB interface.
