ESP32 + PCB Antenna Hardware Design Tutorial - Phil's Lab #90

How to design custom hardware using ESP32 MCUs (ESP32-C3, NOT pre-made modules!) and PCB antennas (inverted F, in this case). PCBs by PCBWay https://www.pcbway.com

Showing examples and real, working hardware (WiFi scan test), a full schematic walkthrough, and a PCB design walkthrough. Final test using Arduino IDE & ESP32 expansion.

Many more ESP32 firmware & hardware tutorial videos to come!
