CircuitPlayground Bluefruit low power tests @adafruit #bluefruit @arduino @circuitpython
Doing some low power testing for a revision of the CircuitPlayground Bluefruit, our prototype has the ability to turn off the neopixels/light/temp/mic sensor in addition to the speaker amp. When we do that, we drop down to 280uA quiescent when we go to sleep (by running delay() in arduino). Running Arduino code is about 6mA.
Here’s what it looks like when we wake from sleep and enable the neopixels and sensors, hang out for a bit, then go back to sleep. there’s a skinny spike of 50mA, maybe the neopixel PWM circuitry turning on at once?

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.
