Frequently Asked Questions

What are the power input options for the FireBeetle 2 ESP32-S3 board?

The board supports three primary power inputs: a USB-C port for 5V DC, a PH2.0 connector for a 3.7V Li-ion battery (with onboard charging circuitry), and the VCC pin which also accepts 5V DC. The integrated power management unit automatically handles power source selection and battery charging.

Does this board support camera interfaces for computer vision projects?

No, the FireBeetle 2 ESP32-S3 (N4) model does not include a dedicated camera interface (DVP or MIPI-CSI). It is optimized for general-purpose IoT, sensor data acquisition, and low-computational AI tasks using its built-in AI acceleration instructions, not for direct image sensor connectivity.

What programming environments are supported for firmware development?

Development is supported in multiple environments: the Arduino IDE using the ESP32 board package, Espressif's official ESP-IDF framework for full feature access, and MicroPython for rapid scripting. The board's bootloader and exposed serial pins facilitate easy flashing via the USB-C port.

How many analog input channels are available and what is their resolution?

The board provides access to 20 analog input channels via two 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converters (ADCs). These channels are suitable for reading a wide range of analog sensor outputs, such as voltage, potentiometers, or various environmental sensors.
