So you have an Arduino UNO with a DIP chip ATMega328P, right? Then add this tiny PCB with a new ATMega328PB chip on it and get more features, such as:
* between 2 and 4 extra GPIO pins
* an extra SPI channel
* an extra I2C channel
* an extra USART (Serial1.print() etc)
* Totally 100% compatible with all your existing Arduino code
Install the *MiniCore hardware core* (links below) and you can exploit the new chip, including some extra commands that were added to the underlying Arduino infrastructure (called 'Wiring') since it went live but were never included!
I demo a quick I2C LCD screen (I had to make some changes to one of the Liquid Crystal libraries as it was hardcoded to use the standard I2C (aka Wire.h) library) but it all worked very well.
The PCB is simple (one SMD LQFP-32 chip and two 0603 100nF caps) and some header pins and you're done!

You don't have an UNO with a removable DIP chip?
---------------------------------------------------------------------------------
No worries! You can pick one up very easily for the price of... yes, you've guessed it, a couple of coffees! See my GitHub for links.
Full details in the video of what you need to do, but it really is childsplay!
