Hi Sparky,

I'm a bit confused as to which header pins to order. I'm quite a novice. I'd be grateful if you can recommend me something from Digikey, Mouser, or Farnell for the following items:

Designator -> Comment -> Quantity -> Package -> Description (as per your BOM file)
J1 -> 24VAC -> 1 unit -> 1x2x4.2 -> Header, 2-Pin
J2 -> IRON -> 1 unit -> 2x2x4.2 -> Header, 4-Pin
J3, J9 -> PWR -> 2 units -> 2x2x4.2 -> Header, 4-Pin
J4, J8 -> CNTR -> 2 units -> 2x5x2.54 -> Header, 10-Pin
J5 -> HOLDER -> 1 unit -> RJ11V -> Header, 8-Pin
J6 -> SENSOR -> 1 unit -> CI31-3 -> Header, 3-Pin
J7 -> 24VDC -> 1 unit -> 1x2x4.2 -> Header, 2-Pin
P1, P2, PD1 -> Header 5 -> 3 unit -> 1x5x2.54 -> Header, 5-Pin

Bests,

You have picture of both boards in the first post. Can't you figure out what the connectors are from there?

The problem is, every manufacturer has his own nomenclature for the same (or compatible) connectors, and I am buying these from local seller. Cvilux in my case. Molex makes them too.

I'll look into Molex then. I have an Economics background. Hence lack some simple know-hows.

Hi Sparky,

Is it true that the voltage VCC is 3.3V? According to Formula Vout = 1.21 * (1 + R2 / R1) voltage is correct 5.00V. I think it's a mistake at R4, instead 1K5 should be 2K7 and then the voltage is exactly 3.316V.

add:

I completed the PCB and now I need iron connection diagrams (Hakko T-12, Hakko 907 Heating element A1321 and Zhongdi desoldering gun ZD-552).

sparkybg, It is mean for both boards assembled with ic

In my country it is around 75-80EUR per set of assembled PCBs.

Yes. This is total cost per set of assembled PCBs, excuding the OLED and some of the connectors, but it is easy to hand solder them.

Black PCBs looks pretty neat. :)

I will have to look at my connectors tonight. Sorry for the delay, but I was on vacation these days.

Hey!

How do you connect a desoldering gun? Do you use some vacuum device? Or are you talking about other kind of device?

Thanks in advance!

very easily ;)
I have the following 2 vacuum pumps:
1) THOMAS Diaphragm Pump 1420VP/12VDC (serie 1420 JADE): -0.78 Bar -> very, very quiet pump
2) "noname" (at eBay € 28): -0.80 Bar -> louder than THOMAS!

Connections to different tips/irons:


1. HAKKO T12:
- Outer shell, and heater negative (middle) terminal connected together to Vout1- and GND
- heater positive (bottom terminal) connected to Vout1+ and SENSEA
- 1k resistor between ID and Vout1-
- 5.6k resistor between ID and Vout2-

2. JBC C245:
- Outer shell (green wire) connected to GND and SENSEB
- Heater positive(red wire) connected to Vout1- and SENSEA
- Heater negative(blue wire) connected to Vout1+
- 150ohm between ID and Vout1+

3. JBC C210:
- Outer shell (green wire) connected to GND and SENSEB
- Heater negative (middle terminal, blue wire) connected to Vout1-
- Heater positive (smaller terminal, red wire) connected to Vout1+ and SENSEA
- 3.0k between ID and Vout1-
- 5.6k between ID and Vout2-

4. JBC Microtweezers:
- Outer shell of both tips (green wire) connected to GND
- Heater 1 negative (blue wire) connected to Vout1-
- Heater 1 positive (red wire) connected to Vout1+ and SENSEA
- Heater 2 negative (brown wire) connected to Vout2-
- Heater 2 positive (yellow wire) connected to Vout2+ and SENSEB
- 1.0k between ID and Vout1-



Hi sparkybg,
is the correct connections for Iron HAKKO T-12?
When these connections, the display shows that I have a "JBC MicroTweezers" connected, which is not true.

Best regarts :)

Check the resistor connections and values. Something is wrong there. The controller knows what is plugged in using these resistors.

More specifically, you have a problem with the 5.6k resistor, or you have a short or open circuit somewhere.

Hi sparkybg,

I checked resistors and values are:
1K0 -> my: 0.999 KOhm
5K6 -> my: 5.606 KOhm

So, all in the green area ;)

before I take apart the PCB board, I would have liked to tried HAKKO 907 iron-connection, but I offer you to these iron-connection diagram.

p.s.: I have the two set completes and both show me the same :(

I was s little busy these days. I will update the first post with HAKKO FX8801 and Weller WSP80 connections tonight.

Thanks a lot for your project. It looks really interesting!


About UniSolder in EEvBlog

I know to have been saying it before, so this will be the last time I post it:

Would you like to put your updated post project of this forum in EEvBLOG too?

I see many reasons:

- It would be interesting more people look at your design and have a nice techie discussion about it.

- People could provide feedback or improvements such as supporting more soldering tools in the firmware or other stuff.

- Your project could have more exposure, others could enjoy your project and you could sell more kits.


Get it reviewed by Dave L. Jones aka "That Crazy Aussie Bloke"

It would be amazing if Dave could build one and try it or get one for teardown and testing. I'm sure many of us can make a little crowdfunding to pay for a fully assembled version to send it to him, I'm sure it could be an important cost to you.

I hope to not broke some rule by mentioning other forum!

About basing my mini project in your design:

I plan to use your design in an all-in-one portable lab suitcase with alarm.

I have many reasons to do it, like organization and avoid stealing me. Long story, but I often forget things due to my ADHD.

I'll put my plans later in both forums ;)
