Circuit Playground 1.5 update is by far our biggest update yet – and as you may have already guessed, it contains much newness and improvements!

Check out some of the new features below:

Op Amp Calculators


Eight Op Amp Circuits total – including such classics as: Inverting Amp, Non-inverting Amp, Summing Amp, Differentiator, Integrator, Differential Amp, Current Source, + a Buffer schematic thrown in for good measure.

Op Amp Pinouts


When you’re ready to build that operational amplifier circuit, swipe on over to the Op Amp Pinout Reference where you’ll find layouts for the most common single, dual, & quad op amp IC packages.

Show & Tell


Got a finished project you’d like to show off? We want to see it! Circuit Playground’s new Show & Tell section lets you easily snap a pic or choose one from your photo library, then send it to Adafruit along with your project description.

Touch schematic components to change values.



On any calculator that includes a schematic, you can now edit input values by tapping the relevant component symbol.

+ Additional improvements throughout


You’ll also notice a quite a few other tweaks and improvements added to make the app easier to use.

Version 1.5 is a free update for all current users – and as always, can be downloaded from the App Store. Thanks again to everyone who purchased Circuit Playground + all the helpful feedback & reviews – do stay tuned for more awesome!
