How to use

• For dependencies on other files please see platformio.ini
• Regarding the board, you can modify the board version and lora frequency in board_def.h
• If you use the Arduino IDE for compilation, please store board_def.h and LilyGO-T-Beam.ino in the same directory, and the directory folder name must be the same as ino

Deepsleep

• Regarding deep sleep, except for DCDC3, power off all channels of AXP192, the current consumption is about 0.9mA
