1. When the high level output of RESET_CONTROL is more than 1.7 V and less than 3.6 V, and the low
level output is less than 0.35 V, it is recommended to use the direct connection method to control the
RESET_N pin of the module. In other cases, it must be controlled by an open collector drive circuit.
2. It is recommended to reserve a 100 nF capacitor position, which is not mounted by default.

In the process of system reset or power-on, keep the BOOT pin input low and the module will enter the
download mode.
In download mode, the firmware can be downloaded through the main serial port. After the download is
complete, the module needs to be reset to exit the download mode.
An open drain/collector driver or button can be used to control the BOOT pin.
