Expansion Design

AR-ES6003FL put CPU and chipset on top of the board and I/O on the bottom of the board. It increases the difficulty of design and manufacture. At the same time, it increases the efficiency of heat transferring because the heat sink is close to the CPU and chipset. It can connect to external heat sink directly that is optimizing thermal solution.
