  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.

  Version 1.1 Stable

  mhu released this 2020-01-12 16:09:39 +01:00 | 57 commits to master since this release

  Changenotes:

  • Replace INA126 opamp with custom circuit

  Errata

  • Silkscreen of C317 and R312 is swapped. Consult interactive BOM for correct placement.
  • Stability of OPAMPs is not guaranteed in this version. You have to make a few modifications
