HT420-A Tweezers support

[nikifena]

Hi there. My name is Niki. I'm PCB and 3D designer and I have been making many /mostly analog/ projects for over 15 years. I checked your project. It looks good. I think to modify it a little bit the board since the tracks going to the pads has no teardrops and it's better to have ticker wires around the pads.

Anyway, I have JBC TH420-A soldering tweezers and I think it's good for having an optional way to power similar tweezers. There is already one free thermocouple input - the spare input of ADS1118. So the only one extra hardware modification will be one wire for the current sense for another VN5E010AH. Both drivers can share the same PWM.

I can modify the PCB with all new improvements but I can't modify the code. I'm a PCB designer.

What do you think about that?

Another "Extra" modification could be two inputs - one for JBC iron and another for iron/tweezers.

Thanks and waiting for your answer.

Niki
