 One trick to get this ridiculously low price is to use STM32F101 micro-controllers.
 Compared to the STM32F103 micro-controllers they offer less functionalities, like USB ... yet this is a USB dongle!
-Well this is because these micro-controllers use the same die, but if not all STM32F103 feature tests pass after production they get packages as STM32F101, and it seems that USB still works well enough.

 At least this is my guess.
-It would be interesting to check if the other STM32F103 peripherals normally not present on the STM32F101 work as well.\\
+It would be interesting to check if the other STM32F103 peripherals normally not present on the STM32F101 work as well, but I wouldn't rely on these.
+After all, they are probably marked as STM32F101 for a good reason.\\
 Similarly the STM32F103C8 is only rated having 64 kB of flash because it didn't pass the flash test, compared to the 128 kB for the STM32F103CB, but they very often have more (you can verify by read/writing and check for errors).

+There is a newer version marked as "V2A" (under the crystal), but the {{:jtag:baite-v2a.pdf|schematic}} is pretty much the small with the following changes:
   * all pads for the micro-controller are present (there is even solder mask between them)
   * they added a SWD port
