Extension board 5V
Posted: Wed Nov 14, 2012 5:28 pm
Hi Tom,
Before assembling the gluonpilot module with the extension board I've verified the tensions on extension board.
I've found 5V equal to 5,463, it's a little bit far from 5.25V (5%). After reading the datasheet of the PTH08080, it seems the resistor Rset (R3 on extension board) must be at 348 ohms to get exactly 5V. However R3 indicates 121, this mean 120 ohms. For 117 ohms the datasheet gives a tension of 5.5V. So it seems to confirm that R3 resistor is not at the good value.
What do you think of this?
Thank you Tom
Regards
Eric
