About: is a global electronics store, which specializes in all kinds of IC products, such DIY Kits, IC accessories, Modules, Robots, Development Board, Transistor, Capacitor and so on. We're located in Shenzhen, Chin…

The ICStation Multi-functional Electronic Calculator Kit is designed to help you build a practical desktop calculator and elevate your soldering skills.

It is powered by two CR2032 button batteries, integrates five different computing functions, and uses a traditional LCD1602 display screen to display the calculation process and results in real-time.

Easy to build and the principle is simple. The connection was clearly mapped and labeled on the PCB board. Soldering time 2-3 hours, suitable for DIY electronics enthusiasts and can be used as school or family education practice kits. Now, let's start the building steps by steps!
