[Introduction]：ECK41-E1N2-N is carefully designed based on Rockchip's RK3506G series processor. It adopts a new stamp hole + LGA interface form. Commonly used functional I/Os are designed on the stamp holes. When only commonly used functional I/Os are used, only the stamp hole pins can be soldered. The ECK41-E1 series core board is a nationally produced industrial-grade embedded core board with the characteristics of low power consumption, small size, high reliability, and high cost performance. This core board can be widely used in the Internet of Things, automation control, smart manufacturing, self-service terminals and other electronic commercial and industrial equipment fields.
