After viewing Redstone's unboxing video for the DS28E18 1-Wire® to I2C/SPI Bridge Evaluation Kit, a DesignSpark member requested if we could do an Ask the Expert interview to learn more about this device from Maxim Integrated. We put the request to Maxim and they were happy to support us.
Joining us for this special product-focused edition is Stewart Merkel from Maxim Integrated.
Stewart has been an Applications Engineer at Maxim Integrated for over ten years. He is skilled in integrating 1-Wire products and hardware security into embedded systems. Prior to joining Maxim, Stewart was focused on telecommunications equipment while working at Odin Telesystems and Raytheon. He holds a B.S. degree in electrical engineering from Binghamton University in New York.
