Generating a negative voltage over -5V is kinda annoying: most chargepumps max out at 5V inversion, and ones that can double-then-invert like the MAX232 aren’t high current. We bumped into the TPS65131 while working on our Floppsy design – we need -12V to bias the Apple Disk ][ drive control system. It’s a combo buck and boost: give it 3~5VDC and give you up to -15V and +15V output. The split supply part is particularly nice because you’ll want +-12V or +-15V for analog projects. This standalone power supply breakout has two mini trim pots to help adjust the output voltages on both sides so you can have as little as +/-6V and up to +/-15V. With the 2A internal switches, you’ll get a fair amount of current on either rail.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
