ESP-NOW Range Test | Built-in vs External Antennas on ESP32

In this video, I test the range of ESP-NOW communication on ESP32 boards using both the built-in PCB antenna and various external antennas. Watch to see how antenna choice affects signal strength and communication distance. Ideal for anyone working with ESP32 in wireless IoT projects.

Hardware used in video:
