Perfect for low-power IoT projects
The E-Ink display is crisp and the power consumption is incredibly low. Setting up the voice interaction was straightforward with the provided examples. Highly recommended for battery-operated sensors.

Excellent integration of features
Having Wi-Fi, Bluetooth, and an E-Ink screen on one board saves so much prototyping time. The ESP32-S3 chip handles the graphics refresh smoothly without lag.

Solid performance for home dashboard
Built a weather station using this board. The display is readable in direct sunlight which is a huge plus. Only minor issue is the speaker output volume is a bit quiet, but acceptable for close range.

Best learning tool for AIoT
I used this for my university final year project. The ability to process voice commands locally and display results on the e-paper screen impressed my professors. Very easy to code in Arduino.

Great board, documentation could be better
Hardware quality is excellent and the Wi-Fi connection is stable. However, some of the advanced voice library examples were a bit hard to find. Once configured, it works like a charm.

Robust and reliable
Been running this board for three weeks straight on a small battery pack. The deep sleep modes work perfectly with the E-Ink retaining the last image. Waveshare did a great job here.
Q: Can I connect a larger external E-Ink display to this board?
A: Absolutely. The board exposes the necessary SPI and GPIO pins to drive larger external E-Ink modules if the onboard 1.54" screen is not sufficient for your project.
Q: Is the microphone sensitive enough for voice recognition across a room?
A: The onboard microphone is optimized for near-field voice interaction (within 1-2 meters). For whole-room coverage, we recommend connecting an external high-gain microphone module.
Q: Does this board support MicroPython out of the box?
A: Yes, the ESP32-S3 chip fully supports MicroPython. You will need to flash the firmware via USB, but the hardware is completely compatible.
Q: What is the maximum capacity of the SD card supported?
A: The board supports microSD cards up to 32GB officially, though many users have reported success with 64GB cards formatted in FAT32.
Q: Does the package include a battery connector cable?
A: Yes, the standard package includes a JST-PH 2.0mm connector cable for connecting a 3.7V Li-Po battery, along with the USB Type-C cable.
