This Basic stater kit is great for beginners who are interested in learning programming. It is easy to learn and brings a lot of fun to learners. You can also DIY more interesting projects by yourself..
There is a ATmega328P microcontroller and expansion board in the kit, we provide 80 components, don’t worry, you definitely have enough accessories to complete your project.
We focus on updating and adding more advanced modules, such as dot matrix module, button module, DHT11 module, DS1302, etc. All modules are soldered, so it is easy to wire..
We attach great importance to product quality control, and have always cared about thecustoms experience and improve the product function details.
This kit is a high-quality kit, which is perfectly compatible with Arduino.

Infrared Dot Matrix SkinLift is a noninvasive skin care procedure, meaning there is no cutting of the skin to perform it, which utilizes high energy to tighten and care the skin and improve its contour..
Infrared Dot Matrix SkinLift works by stimulating the under layer of the skin, known as the dermis and causes collagen creation, called neocollagenesis..
This new collagen makes the skin look firmer & tighter and improves the overall texture of the skin and the body shape. Unlike lasers, the infrared Dot Matrix SkinLift procedure works on all skin types and colors..
Generally patients will usually undergo 8-10 times with Infrared Dot Matrix SkinLift to see visable results. But some people may see differences/improvements just after 1-2 times of use. The Dot Matrix SkinLift stimulates a large volume of collagen in the deeper layers of the skin. Results develop over time and tightening and lifting result can be seen in up to 2 months..
Rechargeable - A full charge takes 3-4 hours and then it can work 30-45 mins. It is small and you can put it in pocket and carry around. It needs to use with water-based gel/lotion/serum during treatment. No brand of product required. Gel not included..
