The Great Search: Pre-Biased Transistors #TheGreatSearch #adafruit #DigiKey #@DigiKey @adafruit
Our cellular module we’re working with now uses a low-voltage IO core, and when we read the datasheet, it helpfully lets us know that we should be using transistors to ‘level / current shift’ the LED driving outputs.
BJT’s require a lower voltage to turn on, but they need resistors to help bias – which turns a single component into a 3-piece network.
To make our board more compact, let’s take a look at ‘pre biased’ transistors – they come in common packages like SOT-23 and a wide range of resistor configurations!
