Request for Soldering schematics / wiring diagram #1

Closed tolkiman closed 3 years ago

tolkiman commented 3 years ago

Step 4 simply states "Connect the SCD30 module to the proto module. We used headers."

I would really like to build this project, however its hard to make out which connections to solder and what to connect exactly. Would you be able to supply a simple wiring diagram / soldering schematics? Thanks!

On page 6 of the datasheet you can see the pin-out diagram of the scd30. You need to connect VDD with 3V3, GND with GND, TX/SCL with pin 5 and RX/SDA with pin 2. The other pins don't need to be connected to the proto module.

Fantastic, thanks for the support!
