There is such an ESP32-S3-Nano board, perhaps someone has dealt with it, and will tell
you how to control the Huawei R4850 power supply, you only need to switch the voltage,
with which library this can be done, I would greatly appreciate an example code,
the transceiver is used on the SN65HVD230 chip, I am grateful in advance for the help!
I moved your topic to an appropriate forum category @rz1zr.
In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
