In my College years, I wanted to learn more about pcb design. I figured the best way to learn a new skill is to exercise that skill constantly, make mistakes, and learn from them.

Before starting this project a new Development board built around the Uno called the Maker Uno was put together by a company that wanted to integrate basic parts onto an arduino uno to make starting projects easier for early makers.

I thought it was a genus idea, and wanted to make my own version and feel proud of it. But when it came time to show it to others, I felt underwhelmed. it was already a finished project, only replacing the Atmega328 with the 32u4.

Thus I begin the works on this design. Learning about the I2C bus, I implemented a I.O. expander, Pwm driver (for Servos and Leds), 6 touch inputs, 12-bit Dac, 16-bit 4 channel ADC, 36+-V 6Amp Watt meter, 18v max boost converter with negative output, lipo charge + protection, and com port connections to SPI, I2C, and UART.
