  • Would this work with the small solar panels here: https://www.sparkfun.com/products/7845

    Those panels say they put out 4.5V and you say the minimum input is 6V. I am fairly new to electronics. I am planning to use two of those small solar panels, could I connect them in series and get 9V as input to this charger?

    I am trying to set up an emergency power source for an Arduino-Xbee-GPS system, that probably uses around 300mA at 3.3V. Even if I cannot run the system continuously that’s okay.

  • I know these can run down to 2.3V, and support using 2xAAA alkaline batteries. But I will still need to get a separate regulated supply to power the common 3.3V sensors Sparkfun sells (pressure, accelerometer etc), is this correct? Or does the PICAXE step-up the voltage itself so I can power 3.3V sensors with 2xAAAs?

    My project is basically a PICAXE with a pressure sensor and a compass which reads data and uses it to turn on LEDs and move a small servo.

No public wish lists :(
