The circular circuit is the running water lamp circuit, which is composed of CD4017, NE555 and leds, which can be used to work after being welded..
Add 2pcs of QFP44 chip, double sided component layout, double welding..
High quality PCB, has clearly marked the electronics components, even beginners can easily solder successfully..
Please make sure all components in right direction and right place.
and check whether pseudo and float welding, this is very important in practicing....

100 % SATISFACTION GUARANTED ★ Excellent quality and an empty canvas for electrical enthusiasts! An easy soldering.
0.1" hole spacing for DIP integrated circuits and headers..
THIS IS NOT YOUR NORMAL PERF BOARD! ★ This board is much higher quality with plated-through-holes and annular rings that will not lift off the PCB under normal soldering conditions.
MUTI-PURPOSE ★ General purpose prototyping circuit board for analog and digital use.
Double sided board with plated-thru holes allows components to be easily soldered to either side of the board.
THE FLEXIBILITY OF HAVINg CHOICES ★ Great assortment with variety of size and perfect for quickly prototyping stackable circuits.
PACKAGE COMPONENT ★ 40 Piece of double sided PCB prototype board in 5 different size (2x8 and 3x7 each 10 Pcs.
7x9 cm each 4 Pcs) with mounting holes or slots on each board corner.

This is an entry-level kit that contains DIY solderable PCB breadboards, male and female Pin headers, LED lights, resistor packages, and jumper packages..
More than 200 pieces of components, compatible with Arduino IDE, Raspberry Pi and other microcontroller boards..

CALCA 11.8" x 328 FT DTF Transfer Film Premium Roll-Double Sided Hot Peel.
Instructions: - Sheet Size: 11.8" x 328 FT/30 cm x 100 m - Print side: Coated - Press time: 10 sec at 302 ℉.
NOTE: This product needs DTF Inks and DTF Powder..
Works on: - Suitable for DTF Inks and DTF Powder. - For use on cotton, polyester, blends, Tri-blends, leather, spandex, and more. - Can be used for dark and light fabric. - A Great soft hand feel..
DTF transfer film is a hybrid Hot peel. This is a solution so versatile that gives you bright colors and is premium coated. You and your customers will be amazed and happy..
Warm Tips: DTF Transfer Film, what is the Single sided? what is the Double sided? Single sided:Rough side is the printing side, back side is glossy. Double sided: Rough side is the printing side, back side is matte and anti-skid..
Double sided:Front side for printing,printing side may be tested with clear Scotch tape pressing peeling for any white nano particles. Double sided flim feeding is more stable than single-sided feeding..

Power up to 10 PC fans from a Single 4-Pin Motherboard PWM Fan Header.Note: Max current limit is 3A in total, check the spec of fan first..
In the hub interfaces, the White interface of FAN1 is the CPU fan dedicated interface (with speed detection function). Since the mainboard can only receive one rotation speed signal, the remaining nine conventional fan interfaces have the PWM function, but no speed signal..
There is EVA double-sided adhesive in the package, which can be easily affixed to a flat place. Also a fixing screw hole in the middle of the PCB to facilitate fixing to a part of the chassis..
Direct computer power supply to reduce the mainboard loading pressure, and PWM temperature control line separated from mainboard to achieve both of power supply and temperature control..
If 3-pin fans are connected to this fan hub, this fan hub CANNOT give them extra PWM function. They will run at FULL SPEED..

-The ultrasonic generator can monitor the power system frequency ultrasound power..
-According to different requirements of users, real-time adjustment of various parameters: The power, amplitude, and running time..
