From the project

ESP32 IoT Gateway board with BLE WIFI and Ethernet

Notice that we use the latest nightly KiCad builds.

1. To reduce noise getting picked by Ethernet clock, disconnected GPIO17 from the CON1 header. Added jumper pads GPIO17_E1 (open by default) if somebody wants to lead it to the header...

1. Added diode D5 on esp_en; 3. Added TVS1 on PHY; 4. Opravi se value na NA(HN1x20); 5. T1 now LMUN2211LT1G; 6. USB connector changed to type C (more popular nowadays); 7. Added r12 and c6; 8. Added CE sign; 9. R28,R31,R32,R33 lowered to 0402 size; 10. DCDC - SY8089 changed to TPS62A02ADRLR. C3 now NA. L2 changed to 1.0uH/2.5A/CD32; 11. Updated the CH340X…
