LoPy4 GPIO pins and LDO regulator



  • There is previous mention that the LoPy module with deep sleep adapter takes control of the internal LDO regulator to change ECO mode or operating voltage using one of the GPIO lines.
    Does the LoPy4 use any GPIO lines to control the mode of the internal regulator? If so which GPIO and what are the modes?
    I wanted to make sure that my GPIO usage was not clashing with any internal LoPy4 functions.



  • I can confirm @River is correct, the LDO automatically switches modes, there is no GPIO pin involved in this



  • @electrozest as far as I know, there is no GPIO controlling the LDO. It does automatically ECO/NORMAL mode depending on input voltage
