6. Lead-free high-temperature solder, environmentally friendly, good strength, and safer for secondary reflow soldering

7. This module is not immersed in gold and is not easily oxidized, making it safer for long-term storage.

8. The unleaded I0 is P0.04 P0.26 P0.31P1.15. The important I0 is on the side. There are a total of 21 I0s available on the side. If the 21 GPIOs are enough, you don’t need to solder the bottom, just ignore it.
