  Release v1.3 Stable

  mhu released this 2020-12-13 20:27:59 +01:00 | 15 commits to master since this release

  Change Notes

  • Add switch mode power supply
  • Add a shielding to the analog part. This is not needed! I just designed it for fun...
  • Add voltage monitoring
  • Add external watchdog IC
  • Fix errata from previous version

  Errata

  • Bridge between GND and EARTH has to be connected. Otherwise the SD Card insertion detection doesn't work.

  Version v1.2 Stable

  mhu released this 2020-02-18 20:52:50 +01:00 | 40 commits to master since this release

  Change Notes

  • Replace single opamps with 4-in-1 part
  • Remove possibility to use an external ADC. Internal ADC is enough
  • Improve ESD protection
  • Fix OpAmp instabilities
  • Improved reference stability
  • Fixed some minor design flaws in layout

  Errata

  • Solder a 100 nF capacitor in parallel to R315 in order to improve noise robustness of the analog frontend. This prevents the wirebreeak detection from tripping, if noise is picked up.
