Soldering Station PCB for 907 iron

This is my latest soldering station project.

The new version is designed on a 2-layer PCB. You can get it from here if it’ s in stock.

Build it using these instructions and this BOM.

Read its manual and download the firmware for the new soldering station.

    Dear friend I am very happy to buy your PCB and help this project.Only two questions: what kind of ceramic capacitor between pins 8-4 on opamp is it necessary? 10n, 100n or other? Also I would like to use LCD module HD44780 16 × 2 RGB so that the color of the LCD backlighting changes as expected WS2812,you can help me?Best regards.Luca

        You need a 100n ceramic cap. If your LCD is compatible with the generic HD44780 module then you could use it. I have to see its datasheet to answer for sure because I haven’t tested it.
        Why do you want to use a WS2811 IC? You could just use a WS2812 LED that you could cut from s atrip which is super cheap.

    hi, great work but it’s sad to see that you did not make this version open source like previous one, i really like to support your project by buying the pcb but for someone like me it’s impossible to do it and it’s because of the place i live. i did build the previous version and i’m still using it. i understand your intent and respect it. keep doing your great work 👍

    I downloaded the file.hex,
    How can I load the firmware on the Arduino Atmega328P? Please note that I have always used the arduino IDE to program the chip.
    I thank you

    In the scheme there are not the NPN transistors.
    I think that one is used for buzzer and one for brightness. It’s true?

      What sheme? The schematic of this station is not uploaded. The schematic from my previous soldering station is totally different and it won’t work with the new firmware. The new firmware will only work with the newest pcb.
