Modular ARM Based System Carrier Board Design and Developments

This article will cover design and development of ARM based modular system for accelerated development in embedded world. Key challenges are to have optimal selection of interfaces which most often used. This list is saturated to well-known and available I2C, SPI, UART, ADC, PWM with higher speed ones which are rarely selected for headers for development boards like SDIO and Quad SPI. Having all those make concept unique and provides flexibility for accelerated development and ease of use. Power domain of the system is modular as well and provides ability to swap on place different designs for PMIC.
