In fact we didn't have this resistor when we switched to TPS2375 and weren't aware of the MPS requirement during sleep. This was causing two issues:1) It turns out most of the customers use these boards on remote locations where sleep and deep sleep are important to conserve power during power downs. Furthermore, most of the customers evaluating which ESP32 board to consider would always measure power consumption in sleep and deep sleep modes. And the boards in sleep would lose PoE power since the PSE would turn off the power supply completely.2) Same thing naturally happened when using the on-board reset button.Of course we would consider your advice for future revisions. I've added notices for future revisions to again empirically measure the load and the temperature and to consider better routing of R41 or/and adding a jumper.Thanks for your constructive feedback.
