Good mic sensitivity
The onboard silicon microphone picks up voice commands accurately even from a meter away. The only downside is that the header pins are not pre-soldered, so you need to do that yourself for breadboard use.

Excellent value for audio applications
I bought this to prototype a smart intercom system. The NS4150 amplifier provides enough volume without distortion, and the P4's dual-core performance handles WiFi streaming easily.

Solid build quality
The PCB layout is clean, and the USB-C connection is sturdy. It boots up quickly and connects to the IDE without issues. Highly recommended for anyone moving from ESP32-S3 to the newer P4 series.

Fast and reliable
Using this for a local voice assistant project. The processing speed on the P4 combined with the dedicated audio peripherals makes real-time processing smooth. No lag detected.

Perfect for AI Voice Projects
The integration of the ES8311 codec and the silicon mic makes this board ready out of the box for voice recognition projects. The audio quality is surprisingly clear for a development board.

Great hardware, documentation could be better
The ESP32-P4 chip is powerful and the amplifier drives my small speaker well. I had to dig into the schematics to find the exact GPIO mapping for the I2S interface, but once configured, it works flawlessly.
Q: Does this board support external PSRAM expansion beyond the onboard 8MB?
A: The board comes with 8MB of octal SPI PSRAM integrated. While the ESP32-P4 chip supports external memory, this specific PCB design does not expose additional pads for expanding PSRAM further.
Q: What is the maximum output power of the NS4150 amplifier on this board?
A: The NS4150 amplifier on this board is configured to deliver up to 3 Watts of output power when powered by a 5V supply and connected to a 4-ohm speaker.
Q: Can I power this board via the VIN pin instead of USB?
A: Yes, you can power the board via the 5V VIN pin. Please ensure the input voltage stays between 4.75V and 5.25V to avoid damaging the onboard components.
Q: Does this board have Bluetooth capability?
A: No, the ESP32-P4 chip used on this board focuses on high-performance computing and AI/ML tasks and does not include Wi-Fi or Bluetooth radio modules. It is designed for applications where connectivity is handled by an external co-processor or wired connections.
Q: Is the microphone analog or digital?
A: The onboard silicon microphone is a digital MEMS microphone that communicates via the PDM (Pulse Density Modulation) interface, which connects directly to the ESP32-P4.
