TEP00002-02 | TEP00002-03 |
Type: PCB Change
Reason: Reduce excessive startup current and cost optimization.
Impact: Less startup current drawn. No further functional impact. Circuit around new DCDCs changed according to datasheet.
Type: PCB Change
Reason: Not needed for optimal operation. Higher sampling frequencies caused voltage drop and non linear behaviour.
Impact: Improved accuracy.
Type: BOM Change
Reason: Improve performance.
Impact: Calibration has to be redone. Measurable maximum voltage is decreased from 38.3V to 35.7V, resolution slightly improved.
The revision number is printed on the top side of the PCB.
Revison 03 is available from February 2021, if you still need the revision 02 please contact us.
Prereleased Revision 03 boards with Serial numbers below and including 566308 have R116 with value 490Ohm and C186 fitted in contradiction to change #2.
