Excellent for Edge AI
The PSRAM makes a huge difference for running TinyML models. Very stable connection and easy to set up with the Arduino IDE.

Decent board
Had some driver issues on Windows initially but resolved after updating the USB drivers. Functionality is fine now.

Good value
Works well for my IoT projects. Wish the pinout was printed larger on the board, but otherwise no complaints.

Perfect for IoT
Using this for a home automation project. Wi-Fi range is impressive compared to older ESP8266 boards.

Fast and Reliable
Arrived quickly. Pre-mounted module saves soldering time which is great for prototyping.
Q: Can I power it via the VIN pin?
A: Yes, 5V can be supplied via the VIN pin or directly through the USB-C port.
Q: What is the power consumption in deep sleep?
A: Deep sleep current is approximately 15uA, though active consumption varies by load and Wi-Fi usage.
Q: Does it support external antennas?
A: This version uses the onboard PCB antenna only and does not have a connector for external antennas.
Q: Is JTAG debugging supported?
A: Yes, the USB Serial/JTAG controller is integrated into the ESP32-S3 chip for debugging.
Q: Is this compatible with MicroPython?
A: Yes, it fully supports MicroPython and CircuitPython frameworks.
