Pwm driver
About the Pwm driver PCB
Pwm driver is an open source PCB design by mjkloeckner, published on GitHub under the MIT license. It is a 2-layer board measuring 35 × 35 mm, with 10 components from 8 distinct parts.
Other key parts include the NE555P. By type, the board carries 2 diodes, 2 capacitors, 2 resistors, 1 IC, 1 transistor and 1 connector.

555 Timer PWM Driver with Schematic, PCB, and Case
This is a simple Pulse-width Modulation Driver that can drive LED strips or other DC loads. The base schematic is taken from Creastive Creator's post on hackster.io.
The majority of 3D Models used are from the official KiCAD 3D library. The ones missing, which the KiCAD 3D library does not include are designed from scratch using FreeCAD (located on pwmdriverkicad/pwmdriver3dmodels`). There's also thrid-party 3D models which have much more detail, for example:
