Excellent power supply system makes power supply for equipment more convenient

Featuring an excellent power supply system, the FireBeetle 2 ESP32-C6 provides convenient device power options. It integrates battery charging management for lithium batteries, enabling charging via Type-C, 5V DC, and solar power. The solar charging capability resolves challenges posed by scenarios without power lines, such as balconies, windows, and rooftops. The FireBeetle 2 ESP32-C6 utilizes the same solar power management chip as the 5V@1A solar power management module, and it is able to maximize the current output capability of the input power source. Additionally, the FireBeetle 2 ESP32-C6 supports battery level monitoring to take necessary measures when the battery is low, ensuring continuous device operation.

FAQ

1. What will cause burning error?

• There is no delay or too short delay in Loop.

• The USB cannot be recognized by the PC as some functions are incorrectlly called.

  

How to solve

• Press and hold BOOT, click RST, and then release the BOOT button to burn.

Principle During the initialization process, ESP32 undertakes a verification of the voltage level on the BOOT (IO9) pin. If the voltage level is determined to be high, the system proceeds with a normal startup. In contrast, if the voltage level is deemed to be low, the device enters into the programming mode. By default, the BOOT pin maintains a high voltage level, but it transitions to a low level when a button is pressed.

2. Data cannot be printed on serial port

• Check if the USB CDC is enabled
• Check print information using other serial debugger.
