2 open source boards using the NPN
Real designs built with the NPN, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

NPN: common questions
Where can I find a NPN reference design?
Each of the 2 boards on this page is a real design using the NPN. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the NPN?
The 05A20H24P, 4*4*1_7, CH340C_USB, ESP-12F(ESP8266MOD) and LDO appear in the most repositories here.
Which microcontrollers do boards using the NPN use?
Most are built on ESP8266 (2).
How big is a typical board using the NPN?
The median is 50.1 × 32.6 mm, and 0% are two-layer designs.
What is the most popular open source board using the NPN?
By GitHub stars, Soldering workshop by Just4Stan, with 0 stars.
Can I simulate one of these boards using the NPN before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
