My OLEDiUNO Spectrum Analyzer with 3 different display modes. It will be also available as a 2 display version that shows the left and right channel separately. For the 2 display version please leave a note and order the analyzer 2 times. Thank you.
I can make it with white, blue or yellow / blue displays. You can also request it in a "clean" look without the frequency numbers. It does run with 5 volt. It can be powered from USB or a cell phone charger for example.
I have fun building with these wonderful OLED displays. I have many more projects and items coming unfortunately time is always not enough to do it all together.
It is just cute and very easy to build into any custom enclosure. The 3 different display modes means there is something for everybody.
Thank you for your interest if you read it this far.

I build the best Atmega328 based micro OLEDiUNOPCB that enables you to connect a I2C or SPI OLED display directly to the PCB. Plus the OLEDiUNO PCB features an on board navigation switch and 2 slide switches and 4 smd LED's in each corner.
Also build the best Grbl based CNC Controller with PWM output, spindle enable and coolant outputs among other features not found on any Arduino shields.
