Re: WIO LTE cat.1 AU version tracker
Hi Yiqian, Whichever version of Wio you use should not affect GPS. If you want to use GPS indoors, I recommended that you can put it next to a window, it might work better.

Re: How to Connect TF Mini LiDAR to USB-to-UART 3.3v/5v Converter?
Hi there, I can't see your picture now, could you check the link of picture? Generally, you can connect TF Mini LiDAR's yellow cable to converter's RX Pin, LiDAR's white cable to converter's TX pin. If you don't know converter's pinout, please see the picture below. https://github.com/SeeedDocument/...
