Wifi connector on Wireless Stick Lite v3

#1

Hi there,

Is there something I have to jumper on the Wireless Stick Lite V3 to use the U.FL connector for an external Wifi antenna or is it in parallel with the onboard Wifi antenna?

Thanks in advance.

“Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi,
Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface
for LoRa use.”

I think the IPX/U.FL connection is for LoRa and WiFi is onboard metal thing and the end of the board.

The Schematic https://resource.heltec.cn/download/Wireless_Stick_V3/HTIT-WS_V3_Schematic_Diagram.pdf shows IPEX connector on the LoRa chip.

At WSL V3 are 2 IPX/U.FL connectors, so one will be for WiFi, I think so (second for LoRa of course).

But it is not clear - is it already connected or must be switched there any “bridge” on the board…
I also would like to install better antenna for WiFi - but not sure how to do it.

Ensure that R15 is connected. If there is a circuit break, simply connect it.

@uther Thanks! Where is R15 located? I think near connector?

@micha-pr did you ever figure it out? I am staring at the board under heavy magnification and have the same question…

Same issue here, I contacted their support who said to remove the resistor below:

They then emailed with a correction “You need remove the original antenna, not the resistor.”
