  • 5 band resistance to color code converter/encoder
  • 6 band resistance to color code converter/encoder
  • 4 band color code to resistance converter/decoder
  • 5 band color code to resistance converter/decoder
  • 6 band color code to resistance converter/decoder
  • 1% - E96 series-parallel best combination finder
  • 5% - E24 series-parallel best combination finder
  • 10% - E12 series-parallel best combination finder



Bbroy is smooth to operate, fast and user friendly. A must have tool for electronic hobbyists, not for color code conversion but for the amazing resistance combination finder. (Electronic hobbyists could have memorized the color codes already.)

You can download Bbroy for free from Google Play Store.
