Hi,
I’ve made simple schematics (multivibrator) containing 4 resistors, 2 capacitors, 2 NPN transistors, 2 pinheads, VCC symbol and GND symbol.
After opening board editor I can’t place transistors - they haven’t pinouts.
Can somebody explain how to place transistor on board.
I think - you used the transistor from LibrePCB Base library, which haven`t assigned a package to symbol (Device doesn’t exist). Due to this, you can place a symbol to schematic, but not footprint (package) to PCB.
Try to look inside this library: https://github.com/EdizonTN/Diotec.lplib
Content some common PNP and NPN transistors with assigned package (Components for schematic are created and Device for PCB also)
