Solar Module DC Power Source

Replacement: None. Due to poor sales, we have decided to remove this item from our catalog. This page is for reference only.

This is a small solar power module designed to plug directly onto the MSP development boards but can be used with any 3.3V system. This includes a small solar panel and a AA battery holder. Perfect for low power projects that need rechargeable 3.3V power.

Includes cable as shown.

  • SOLAR PANEL 2.4VDC 80mA with DC/DC voltage boost converter
  • JTAG connector for direct plug in MSP430 2x7 JTAG connector to provide power for the target board
  • Suitable AA sized rechargeable batteries
  • 56x48 mm (2.2x1.9")

    I'd love to see an in-house version of this, beefy enough for 5v Arduinos, with barrel-jack input/output and maybe even a JST plug for lipo's.

      It's a more expensive, but the LiPoly charger can take the "small" solar cell as an input. A 5v step-up is all you'd need to power a 5V Arduino, but are you sure you want to run a solar project off of 5v?

    Nice.. HOWEVER.. It breaks one of the Maker Rules, or it should be. No easy way to mount or place in box without connector getting in the way.
    Haven't tested it yet other than on the bench. South Florida is either sunny, or DOWN POURS!

    so this is a aa battery pack with a solar cell attached to a 5v step up so like this will bring current up to a 5v level?
    also say i dont have that board u hve the jtag for could i run this off 2 connectors on the board so i can attach this product alone on say a arduino?

    With a 2300mAH 1.3V NiMH battery and a 330 ohm resistor load on the output I'm seeing 3.05 volts. That's only 9mA.
    I also noticed that the no-load voltage is 3.7V not 3.3V as advertised.
    I looked closely at the part on the board and the package is marked "DBKRLW". According to the datasheet that's a 38T1 part (3.8V) not a 33T1 part (3.3V).
    I'm a sparkfun fan and have lots of your stuff, but this one is not really good for much.

    false advertisement, the current in the sunlight is approx 15mA.

    • SlyVixsky / about 12 years ago / 1

      was this direct sunlight? or was this through a window, or on a slightly overcast day? was this at noon, morning, or afternoon? it all affects how 'direct' the sunlight is and the ammount of power you will get from the solar cell

    I second this, and would purchase two of them.
