Good day! I need to use 4 character 7 segment for my project. Even with dynamic indication it takes too much pins and too much code. Is there any option to get controllable over serial or I2C (or anything else) 7 segment? Can it be cheaper than 16x2 character display (less than $9)?

Cheap and simple 7 segment led 4 characters

Thanks for the response. What MCU is inside this module? Is this AVR or something other?
