ESP32-C3-13 external antenna
Posted: Tue Mar 12, 2024 6:22 pm
Hi,
I am using ESP-NOW to communicate two ESP circuits. My aim is to get more gain trying to attach external antenna to AiThinker ESP-C3-13 Node MCU kit. Module is coming not soldered male interface on board. Therefore I soldered an IPEX connector to board. After the soldering connector I attached the external antenna to the board but nothing changed. Still same dbi and no extra gain.
Has ESP-C3-13 a trick like ESP32-CAM (https://randomnerdtutorials.com/esp32-c ... al-antenna) to enable external antenna instead of on-board one?
As an additional information; I tested short-circut positive and negative pins of IPEX connector without attaching an antenna. Then found out they are touching each other at some where. It is same on brand new board to. Is it normal?
Please find my part attached to the message.
Thank you for your helps.
