PCB for Digital Soldering Station (Hakko 907)
Included is PCB, IRLZ44N and the Buck Converter.
The rest of the components you will have to source.
I built this one myself, works good, but the led resistor should be 220 ohms and not 2.2K ohms.
I used a 24Vac 3A power transformer for the one I built.
Also, use a 470uf 50V capacitor and not a 25V one.
The buck converter specs is step down
– in 4.5 – 28Vdc
– Out is adjustable 1 – 20Vdc
