## Questions & Answers

**Q: If the oled screen uses sda and scl pins, how can i also use a sensor (ir temp) that also uses sda pins?**
A: Theoretically, you can connect up to 127 I2C devices to the same pins not just two. This is because each I2C device has its own different address that uses to send/receive data.

**Q: What needs to be soldered?  Anyone get it going on tinygs??**
A: This may be a stretch for TinyGS. It DOES NOT work out of the box. This is a V3 which is not compatible with TinyGS at this (04.2023) time.

**Q: What needs to be soldered?**
A: Only the the header pins and you don't even need to solder those in if you are not mounting it on a PCB or breadboard.
FWIW, I just took mine out of the box and plugged it into an antenna and the computer. I have never had to solder anything.

**Q: Device does not power on via usbc.  requires a battery connected to turn on.  tried about 6 different usbc cables and outlets.  this a feature?**
A: It should work without a battery.  If yours doesn't run off a USB cable the battery will never get get charged.  Sounds like a return is required.
