ESP32 One Kit






ESP32 One is a development board powered by ESP32-D0WDQ6-V3, which features 802.11 b/g/m and BLE4.2.
The ESP32 One integrates power circuits, users can power the board by USB adapter or 4.2V batteries pack. The ESP32 One can be used for image recognition, voice processing, and more...
The ESP32 One Kit has an OV2640 Camera, and the ESP32 One doesn't.


  • OV2640 camera (optional) and digital microphone, supports applications like image recognition, voice processing...
  • Standard 40PIN GPIO header, compatible with Raspberry Pi HATs for sorts of IoT applications.
  • Integrated Li-ion battery boost charging manager, supports battery charging/discharging, and can also be powered from the USB connection.
  • Compatible with Arduino and ESP-IDF software SDK, seamlessly connecting with ESP-WHO applications.
  • Onboard 8MB PSRAM, 4MB FLASH storage, supports SD extension as well.
  • CP2102 USB to UART converter, for serial debugging/programming.
  • 4x LED indicators, make it easy to check the operating status.

Software Setup

The guide is based on Windows 10 PC. To develop the ESP32 one, you can use ESP-IDF or the Arduino libraries, for easy development, hereby we use Visual Studio Code.
If you want to use the board in Mac/Linux PC, please refer to ESPRESSIF's guides.

Install ESP-IDF

Download and Install ESP IDF tools
  • Install the ESP IDF and keep the default setting. (It will automatically install Python3.7, Git tools and configure the environment parameters).

e-Paper Examples

1. Download the e-Paper ESP32 Driver Board Examples, open the DEV_Config.h file and modify the pins as below table.

PIN ESP32 Description
VCC VCC Power(3.3V input)
SCK 13 SCLK pin of SPI interface, clock input
DIN 14 MOSI pin of SPI interface, data input
CS 5 Chip selec, low active
BUSY 4 Busy status output pin (High for busy)
RST 19 Reset pin, low for active
DC 0 Data/Command pin, Low for command and High for data.

2. After modification, enter examples\ directory, copy the esp32-waveshare-epd folder to \hardware\espressif\esp32\libraries, which should be under the installation directory.
3. Connect e-Paper Driver HAT to the ESP32 One, and connect e-Paper to the HAT. Open VS Code as administrator. Open the e-Paper project (Choose the one according to the type of your e-Paper)
