To learn more, see our tips on writing great answers. Witch esp32 firmware did you use? The trace for the clock is ca. ), but TX (and therefore DHCP and communication) won't work (I ran tcpdump on a machine directly connected to the board). It was designed to be produced in my PCB mill. It is highly recommended that the user code turn off the ethernet clock by lowering GPIO 12 before a soft restart. Address pin is configured correctly? If your PCB mill can handle QFN24 footprints and double-sided PCB's then you might be able to duplicate this. The role of each GPIO and their functions are documented in further detail later in this guide. Already have an account? It will initialize the reset GPIO to output mode, drives it to low (e.g. Part of the PCB layout is now attached above (I can also share the EasyEDA Project). In this example, the RTL8722 board emulates a HID keyboard connected using BLE. If you need to use these pins, please solder a module without PSRAM memory inside, e.g. sensors will need to stay a minimum of 10cm off the board to avoid the heat The final scheme is shown here. privacy statement.
