Overview

Geekworm ESP32 WROVER-i DevKit is a low-footprint, minimal system development board which is powered by our latest espressif ESP32-WROVER PCB Antenna module and can be easily adjusted to a breadboard, and build in ESP32-WROVER Module ipex version module.

Update Notification

In March 14 2019, this ESP32-WROVER development board has been updated to a new version with PCB antenna module according to the customer feedback. The previous IPEX antenna module version has been discontinued now.

New and Powerful

Built around the ESP32-WROVER Module ipex module, this minimal system development board achieves optimal performance with its rich peripheral set, Wi-Fi and Bluetooth radio solutions, which are offered by our latest SoC, the ESP32. The limit is your imagination!

Rapid Prototyping

Get right into application design and development without worrying about RF performance and antenna design. The DevKitC has your basic system requirements already covered. Just plug in the USB cable and you’re good to go!

Flexible and Feature-Rich

The WORVER DevKit contains the entire basic support circuitry for the ESP32-WROVER Module, including the USB-UART bridge(CH340), reset- and boot-mode buttons, LDO regulator and a micro-USB connector. All pin export GPIO is available to the developer.

Breadboard-Friendly

The WORVER DevKitC pin out is optimized for prototyping on a breadboard.

FAQ

Q1: How to use this board with arduino ide?

A: ESP32 WROVER is only a module of the ESP32 series, and ESP32's arduino documentation is suitable for esp32 wrover.please refer to here: https://github.com/espressif/arduino-esp32


Q2: What to do if you have meet some problem with this development board?

A:

1.Please install the CH340 USB driver. In addition, please restart the computer. For the CH340 USB driver, please refer to: File:CH341SER.ZIP If you can't find the device, please temporarily remove other USB devices and try again. (Note: There are some unknown reasons that may interfere. Sometimes we also find that the USB device cannot be found during the test.)

2.It is probably that the driver's conflict problem caused our WROVER can not to be recognized; or you can try to use a new computer to test.

3.Now the ESP32 WROVER IPEX Development Board has updated with 8MB PSRAM, and the board write 4MB PSRAM as the PCB do not update, but actually it use ESP32-WROVER-B Module with 8MB PSRAM. The development board is depends on the ESP32-WROVER module. please refer to: https://www.espressif.com/sites/default/files/documentation/esp32-wrover_datasheet_en.pdf

4.We just bring out the PIN of this ESP32 WROVER-B module to facilitate the use of developers. We added the CH340 USB driver chip on it.


Q3: Why my esp32 model doesn't work in wifi? The module cannot connect to my access point. Sometimes, it can freeze my PC.

A: Please try to update the official firmware (change the version of ESP32 IDF from v3.1 to v3.2), please refer to: raspberrypiwiki.com/index.php/ESP32_WROVER-i_DevKit


Q4: Why the esp32 wrover development board failed to connect the wifi after the official firmware is swiped?

A: When activating the wifi, the development board will perform a leakage check. It needs 1) 500mA current 2) the USB power supply port and 3) a good data cable, only when meet the requirements can it activates successfully.

Externally, the promising module turned out to be defective, when you try to use Wi-Fi and power it from USB3.0, it infinitely reboots. Cables are high-quality, ESP-IDF 3.2 and 3.3RC, any other module works under these conditions. If we add an electrolytic capacitor to the output of the 5V module and short-circuit the diode D1, then the module starts to work normally. The voltage drop on D1 is about 0.5V. We must try to replace D1 with a diode with a lower voltage drop.

The module restarts endlessly when powered by USB and using Wi-Fi. Uses high-quality USB cables, several verified. Modules from other vendors work without problems. When trying to use Wi-Fi, this module reboots endlessly when powered by USB using ESP-IDF ver.3.2. and ver.3.3-rc as well as with any other.

The micro-usb socket on these boards is attached EXTREMELY POORLY. The solder they are using does not adhere to the ground casing of the socket, so any lifting force at all will cause the socket to pop off as it did on mine almost immediately.

While I did manage to solder it back on, hopefully for good they really need to pick a better socket with more and longer legs (that extend right through the board), and add thermal reliefs around the legs so that they can be heated properly while soldering. Even with a 250 watt soldering iron, it was hard to get the solder to melt with the heat being conducted away through the board.
