Good evening to all,
We have built a board with the ESP32-WROOM-32-N16 controller (https://www.lcsc.com/product-detail/WiF ... 29581.html).
we have made two orders with the same characteristics without changes in program and circuit, let's call them A and B.
The A order boards have a normal function without problems.
The B order boards show a normal operation without problems but after a period of operation we notice that the program delete from memory of the controller or the eeprom data deleted who have registered by programming through the eeprom.h library.
The programming of the board is done through the platform arduino ide with board DOIT ESP32 DEVKIT V1 and the data is passed by the PL2303 as mentioned in the link below https://www.espressif.com/en/products/modules
Does it matter which BOARD from the aduino platform I should choose for programming the board?
Has not been properly designed as regards the strapping pins of the controller?
Does gpio16 need to be at 3.3 volts through a 10kΩ resistor ?
