AZ OLED setup kits for Soekris dam1021/1121 control

If this 2 holes do not fit well into the solder, they can also be filled with heat conductive silicone rubber. The easiest way is to add a memory radiator to the 4701/3301 chip.

Thanks for your fast answer.

I'll check if there ist enough solder under the chips for best heat conduction.
I desoldered the old 3301, perhaps I'll give the old one another chance. Otherwise I'll wait for the new chips.

Talema transformers don't seem to have dual AC10V specs. With dual AC12V transformers, be sure to solder the heat holes behind the 4701/3301 chip or add heat sink to the chip. Please note that there are altogether 4 heat conducting holes. Please warm it up first, because the copper sheath is thermally conductive. Also, don't solder it too long.

Check it out. There are 5 heat holes. Please fill in the soldering to conducte heat.
