MCB900: Power Supply Problem on MCB900 V4

Information in this article applies to:

  • MCB900 Version 4 - Early Versions


I have a problem with the power supply on MCB900. The ADC generates wrong results because the voltage regulator appears to be oscillating. How can I solve that issue?


There was a problem on early versions of the MCB900 V4 Board. The capacitor C10 should be a 10uF Tantalum (+ polarity on label If you change C10, the board will work fine.
