Excellent power management
Specifically bought this for its low power consumption claims, and it delivers. My solar-powered weather station has been running without issues through cloudy days.

Reliable and easy to program
Works flawlessly with the Arduino IDE and ESP-IDF. The built-in antenna performs better than expected in my smart home setup. Very happy with this purchase.

Great board, minor documentation gaps
Hardware quality is excellent and the WiFi connection is stable. However, finding specific pinout diagrams for the low-power modes took some digging in the forums. Otherwise, highly recommended.

Perfect for low-power IoT projects
The deep sleep capabilities on this board are impressive. I've been running a sensor node on a single battery charge for over three weeks. The form factor is also great for compact enclosures.

Solid performance for the price
I use these in a fleet of small robots. They handle dual-core processing well. The only reason for 4 stars is that the USB connector feels slightly fragile compared to other boards.
Q: Is there a separate antenna connector for external antennas?
A: This specific model uses an onboard PCB antenna. If you require an external antenna connector (IPEX), please look for the FireBeetle ESP32-E variant.
Q: Does this board support MicroPython?
A: Yes, the FireBeetle ESP32 is fully compatible with MicroPython. You can flash the firmware using esptool.py and start coding immediately.
Q: How many PWM channels are available?
A: The ESP32 chip supports up to 16 independent PWM channels, which can be mapped to almost any GPIO pin on the FireBeetle board.
Q: What is the maximum current draw in deep sleep mode?
A: In deep sleep mode with RTC memory retained, the current consumption is typically around 10 microamps, depending on your specific peripheral configuration.
Q: Can I power this directly from a 5V USB source?
A: Yes, the board includes an onboard LDO regulator that allows you to power it via the VIN pin or USB with an input range of 3.3V to 5.5V.
