Perfect for IoT Weather Stations
This board works flawlessly with my 4.2-inch e-ink display. The WiFi connection is stable, and the Arduino libraries provided by Waveshare made setup incredibly easy. Great value for prototyping low-power devices.

Solid hardware, documentation could be better
The ESP32 module performs well and the pinout is clearly labeled. I had to dig into the GitHub repo for specific pin mappings for the 7.5-inch screen, but once configured, it runs smoothly. Recommended for experienced users.

Excellent build quality
The PCB feels sturdy and the soldering points are clean. I appreciate that it comes with the header pins included so I didn't have to source them separately. Works perfectly out of the box.

Great for learning embedded systems
Bought this for my university project on low-energy displays. It connects to Bluetooth instantly and the power consumption is exactly as expected for an ESP32. Very happy with the purchase.

Good compatibility with MicroPython
Flashed MicroPython onto it without any hassle. The e-ink library works well, though refreshing full screens takes a moment as expected with this technology. A reliable choice for developers.

Reliable wireless driver
Using this to drive a dashboard display in my smart home setup. The refresh rate is good for static information, and the wireless range covers my entire workshop without issues.
Q: Does this board support the 7.5-inch three-color e-paper display?
A: Yes, this driver board is compatible with most Waveshare E-Paper modules, including the 7.5-inch three-color variants. You will need to select the correct example code for your specific screen resolution.
Q: Is the USB port used only for programming or also for power?
A: The Micro-USB port serves both purposes: it can be used to upload code to the ESP32 and to provide 5V power to the board and the connected e-ink display.
Q: What is the maximum resolution supported by this driver?
A: The board itself does not limit resolution; it depends on the specific e-ink panel you connect. It successfully drives panels ranging from 128x296 up to 800x480 pixels.
Q: Are there sample codes available for ESP-IDF framework?
A: Yes, Waveshare provides a comprehensive wiki with demo codes for Arduino IDE, MicroPython, and ESP-IDF. You can find the repositories linked on the product page.
Q: Can I power this board directly from a 3.7V LiPo battery?
A: While the ESP32 operates at 3.3V, we recommend using the 5V input pin with a regulated power source or a battery module with a boost converter to ensure stable performance during WiFi transmission peaks.
