I collected a bunch of BGI Beidou positioning modules from the seafood market and made this verification board. I collected a bunch of BGI Beidou positioning modules from the seafood market and made this verification board.
The board leads out all the interfaces of the module except the antenna. There are specific pins printed on the board. The board has been successfully verified. The 16p typec interface is used. For ch340c, use two jumper caps to convert usb-ttl to choose whether to use ch340.
Test software and module data manuals are in the engineering attachments
When using an active antenna, you need to solder the 39uh inductor. When you use a passive antenna, you don’t need to solder it.
