Curiosity s-Card
About the Curiosity s-Card PCB
Curiosity s-Card is an open source PCB design by mat808ofc, published on GitHub. It is a 2-layer board measuring 90 × 60 mm, with 12 components from 12 distinct parts.
Other key parts include the NT3H2111W0FHKH. By type, the board carries 8 resistors, 1 IC, 1 diode and 1 capacitor.
From the project
My own custom business card.
Vf - The forward voltage is the voltage it needs for a given current. If - The forward current is the current actually flowing through the LED. Controls brightness. This is the value you target. Everything else in the calculation exists to make sure this number ends up where you want it. They are related to each other. When more current flows through, Vf goes up as well. Vsupply: the total voltage available from the source (VOUT, ~2V in this case) VLED (Vf): the voltage the LED itself consumes at THE CHOSEN CURRENT!!
