4. BOM - greenjacketgirl/Solar_Charger GitHub Wiki
Materials List
I also have a digikey BOM located in the documentation folder under the CODE tab, or you can find it here. Note that I still need to add a few parts to this list. I will be updating it here soon with the correct parts, correct number of parts, and including prices and other relevant notes I found helpul.
