In the hot summer, you need a cool ground-self-made water cooling system (nine welding preparations -_-!!)

We received express delivery at noon today. SF is not cheap, and it is indeed fast. Direct air parts.

Open the package and use a small box with two groups of circuit boards.

The main control circuit board and display and control circuit board are packed in shockproof foam.

Black and white characters are separated and the luster is good.

We scanned all the boards with the naked eye, and the quality was indeed good.
I actually got 12 boards and sent two more. It is estimated that there will be a lot of boards in production. 10 boards with no defects. No disconnection or short circuit is found during cabling. The silk screen is clear and in good condition. If the photo contains silk screen defects, the image is provided with multiple copies, so you can ignore the defects ^.
Come to a front

Back

All the flaws are problems in the design document. One is the 3.3v Pressure Control Tube for heat dissipation. If no result is set, do not overwrite Solder Mask oil -_-!!

In another aspect, I made my own claim to reverse the logo text on the back. The consequence is that the logo on the back is reversed!

The chicken has been frozen yesterday, and today it is not so frozen. Prepare welding components.
List of components exported directly from the design File

Cup thing happened! All the originals in the list are available, except for the SMD capacitor, which means there is no such thing as Oh ~~~~~~~~~~~~~ Oh, my God !!! Faint now ~!

Today, welding fails. Send a post to vent my small gloomy heart ~
