The Adafruit Constant Current Boost Converter for LEDs makes driving LEDs easy, whether they're in series or parallel - with a chip that can generate up to 40V and 400mA from 3~5V input. Unlike most of Adafruit's booster chips that generate a fixed voltage (like 5V, or 12V) the TPS61169 increases the voltage until a set current is being drawn. That makes it excellent for LEDs, that are specified in current not voltage. Perfect for use with LED noodles and filaments , where sometimes you need up to 12V or 24V, at 200mA or so. Also excellent when you have a bunch of 3V LEDs in series, so they ad
