Analog panel meters are not as blingy as LEDs but they add a touch of elegance and are easier to read quickly.This one is fairly large and is easy to open up the front with two screws and replace the gauge. There's a 'zero adjust' as well. The back has four 3mm (4-40)...

We've upgraded this RTC breakout and made it even easier to use! Now available as a fully assembled board, it has the same components, chip, size, etc but you don't have to put it together. It's also less expensive! Check out...

This is a cute, half-size breadboard with 400 tie points, good for small projects. It's 3.25" x 2.2" / 8.3cm x 5.5cm with a standard double-strip in the middle and two power rails on both sides. You can pull the power rails off easily to make the breadboard as...

Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype - usually starting with a solderless breadboard and then...

Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the FTDI Friend!The FTDI Friend is a tweaked out FTDI FT232RL chip...

If you need to connect a DC power wall wart to a board that doesn't have a DC jack - this adapter will come in very handy! There is a 2.1mm DC jack on one end, and a screw terminal block on the other. The terminals are labeled with positive/negative assuming a positive-tip configuration...

This is a really nice power supply. It's a switching DC supply so it's small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 9V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel...
