  • I have problem using this with an Arduino, as the stepup voltage converter for the backlight leds generates severe ripple back to the source. Connecting the VBATT input to the +5V pin on the Arduino gives a 200 mV p-p ripple!, which severely affects ADC readings on the Arduino. Disconnecting the VBATT pin (turning the backlight off) lets the Arduino ADC work peacfully but the measured values are hard to read… ;-) Is there a good way to eliminate the ripple?

No public wish lists :(
