Is it possible ot design an Arduino for a complete part cost under $10? WIth the ATSAML10E14A, it just might. In this article, I explain the rules, and the concept for my approach to designing an Ardunio with a BOM cost under $10.

Last article, I briefly covered some of the hardware inside of the PIC32MZ devices, but now the time has come to start putting digital pen to digital paper and start designing a board. i chose to start from Callisto since its a working design and has much of the needed external hardware design done. So, its only fitting that the paternal twin sister card to Callisto be dubbed Europa.

While I’m reading up on the PIC32MZ, I thought it would be good to knock out a quick expansion card for Callisto, and the new PIC32MZ boards. I wanted this breakout card to incorporate lots of connections for sensors and servo boards, but also fit within the profile of Callisto.

I do a lot of work with the STM32 family of devices, and for the most part they are pretty awesome chips. Recently, however, I found some samples of the Microchip PIC32MZ in my lab and wanted to put them to the test. So it’s time to fire up the EDA tools, and design a board again.
