ICStation GY20433 Manual

1.Introduction:
It is a calculator DIY soldering module.It can perform
addition,subtraction,multiplication,division,negative numbers,and decimal point operations.
2.Feature:
1).It uses in-line components and is easy to solder.
2).It doesn't require a computer,the calculator kit is pre-programmed.
3)It is powered by a single CR2032 battery and can be carried anywhere without being
tethered.
4).It can be turned on instantly,turned on at any time,and easy to use.
5).When not in use for a long time,it can automatically sleep,saving energy.
3.Parameter:
1).Product Name:Calculator DIY Soldering Module
2).Battery:CR2032
3).Digital Precision:6 digits
4).Welding Method:in-line component welding
5).Work Temperature:-25℃~85℃
6).Work Humidity:5%~95%RH
7).Size(Installed):90*91*18mm
4.Precautions for Welding and Installation:
1).The components are soldered on the front of the board (screen printing surface),from
low to high,that is,first low-solder components,such as mega328 (pay attention to the IC
direction),capacitors,resistors,battery holders,then solder the switch,and finally solder the
digital tube .
2).Use diagonal pliers to cut the excess pins as short as possible.
