7. FAQ

•
I received ESP32-GATEWAY and expected USB micro connector but the board came with
USB type C connector. Was there a mistake?
◦ No. We updated the design with USB type C connector in 2024. It is the more popular
connector nowadays.
•
I have ESP32-GATEWAY and it appears Ethernet is generating a lot of noise. How can I lower
the noise?
◦ In hardware revisions prior to revision H, this might be caused by bigger than needed driver
strength set by the software on the Ethernet clock pin (GPIO17). Lower the drive strength of
the digital output num 17 from the default value 20mA to 5mA. There are usually 4 levels of
strength from 0 to 3.
In Arduino this can be done with:
gpio_set_drive_capability((gpio_num_t)GPIO_NUM_17, GPIO_DRIVE_CAP_0);
and also you need to include at top:
#include "driver/gpio.h"
PlatformIO installation.
– after installation – there is own entry for the board, it
