Reliable Wi-Fi range
I replaced several older ESP8266 modules with these. The Wi-Fi signal strength is noticeably better, and the dual-core processor handles multiple MQTT topics without lag.

Great performance, minor pinout learning curve
Processing power is excellent for image recognition tasks using TinyML. The only downside is that the pinout differs slightly from the standard ESP32, so check the schematic before wiring sensors.

Perfect compact board for IoT projects
The form factor is incredibly small yet packs all the necessary features. The native USB support makes flashing sketches instantaneous compared to older boards. Highly recommended for wearable tech.

Ideal for university robotics class
Bought this for a final year project involving Wi-Fi controlled robots. The Bluetooth LE connectivity is stable, and the community support for the S3 chip is growing fast.

Good value but needs careful handling
The board is tiny, which is great for space-constrained projects, but the pins are close together. You need a steady hand or a breakout board for prototyping. Otherwise, it works flawlessly.

MicroPython runs smoothly
Flashed MicroPython immediately out of the box. The 8MB PSRAM allows for complex scripts and buffering data logs locally before sending them to the cloud. Very impressed.
Q: What is the maximum resolution supported for the camera interface?
A: The DVP interface supports various resolutions depending on the camera module used, typically up to UXGA (1600x1200) with OV2640 or OV5640 sensors, limited by PSRAM availability.
Q: Can I power this board directly via the VIN pin?
A: Yes, you can supply 5V to the VIN pin, and the onboard regulator will step it down to 3.3V for the MCU. Alternatively, use the USB-C port for power and data.
Q: Does this board support external antenna connections?
A: No, the Waveshare ESP32-S3-Zero uses an onboard PCB antenna only. It does not have an IPEX connector for an external antenna.
Q: Does it come with headers pre-soldered?
A: No, this board is shipped without headers to maintain its low profile. You will need to purchase and solder male or female headers separately based on your project needs.
Q: Is this compatible with the Arduino IDE?
A: Absolutely. You just need to install the ESP32 board package by Espressif Systems in your Arduino IDE preferences and select 'ESP32S3 Dev Module' as the board type.
