- Capable of running 3V and communicates with 5V logic
- All the pins you need to setup your RS232 to TTL connection are broken out
- Some basic soldering and rookie coding skills are required
The 'must have' IC for TTL/CMOS projects finally has its own breakout board! This is the RS232 converter IC that is capable of running at 3V and communicating with 5V logic.
Sparkfun has taken the SOIC package MAX3232 and broken out all the pins you need to set up your RS232 to TTL connection. They've also included the necessary 0.1uF charge pump capacitors. Also remember that because the MAX3232 operates at a broader voltage range than the 232 (3 - 5.5V) you can use this on both your 3.3 and 5V projects!
Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need. You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL. You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
