B/Boot Button: Puts ESP32 into boot/flash mode. Hold while connecting USB for firmware updates or troubleshooting.
2.4GHz Frequency Limitation
The ESP32-WROOM-32UE chip and antennas operate on 2.4GHz, so testing will work on 2.4GHz networks. Deauth attacks will not work on every network due to 5GHz frequency limitations or enhanced security protections.
Antennas
The Mini board requires a specific antenna for optimal WiFi performance. Look for the frequency label (2.4GHz) printed next to the antenna connector on the board.
