Hello everyone, I have a relay module with the code HLK-SW16_V3.1. I recently made a mistake. I briefly connected a DC 12V voltage to the module. The result was that the Wi-Fi module LEDs went out instantly. There was no burning, darkening, or smell on the main board. When I connected it again to 5V DC, the blue light on the main board blinked and there seemed to be no problem. What do you think I can do? Can I obtain a replacement Wi-Fi module? If I find one, and there seem to be sellers online, I don't know the exact product code. What is the appropriate Wi-Fi module product code? Also, if I find the same Wi-Fi module, will I need to reprogram it? Will I need to install any additional software to reactivate the relay board? Or are these boards plug-and-play? Many thanks in advance to anyone who can help me with this. Sincerely

Hello, Thank you very much for the quick reply. The HLK-RM04 module I need is sold in my country, Türkiye. However, the seller doesn't have enough information regarding whether this Wi-Fi card is an HLK-RM04 module with firmware compatible with the HLK-SW16 relay application. If this card doesn't have compatible firmware with my HLK-SW16 relay card, could you help me install the appropriate firmware? Regards
