One can find here useful utilities to use when designing and prototyping PCB electronics. For instance a simple Excel spreadsheet with a resistance divider finder compatible with all sold on Aliexpress.Click on each individual file above to download.
- resist divider calculator.xlsx suitable for the ICs AUR9718, ST1S09
- resist divider calculator - MP8765.xlsx suitable for the IC MT8765
These are Excel spreadsheets with all values of SMD resistors typically sold on AliExpress. This spreadsheet allows one to determine a pair of resistances to use for a given resistance divider (R1/R2)
