About the 12V step up PCB
12V step up is an open source PCB design by marcusmueller, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 32 × 46 mm, with 18 components from 14 distinct parts.
Other key parts include the TLV61048. By type, the board carries 8 resistors, 3 connectors, 3 capacitors, 1 IC, 1 diode and 1 inductor.
From the project
General purpose Step-Up converter
Was warm. Did not find a good source for an affordable, compact, not-made-of-counterfeit-components step-up converter. Designed something that JLC would manufacture for me.
Note this was an exercise in rapid design, more than beauty.
CERN-OHL-S v2 for the schematic, layout and TLV symbol.
The footprint and symbol for the USB connector have been sourced from JLC/LCSC's EasyEDA library, https://www.lcsc.com/product-detail/C2988369.html , and converted to KiCAD automatically. License there is
