Since the launch of NXP i.MX8M Mini series chips, electronic engineers boiling, want to try to start. Embedded Boards Mill company pioneered electronic MYC-C8MMX core board and the development board based on i.MX8M Mini processor. The following Xiaobian together to see this core board it.
The set plate assembly 8M Mini developed by the core plate and the bottom plate MYC-C8MMX MYB-C8MMX from:
8M mini core board
8M mini core board (Model: MYC-C8MMX) using NXP i.MX8M Mini series CPU, integrated power supply chip ROHM, DDR4, eMMC memory and 200PIN industrial connectors. MYC-C8MMX has the characteristics of high performance, high cost, long delivery times, for applications that require high-performance intelligent key board apparatus required.
