Description
SOM-860-E is a small form-factor controller board based on TI’s Sitara AM3354/AM3358 ARM Cortex-A8 processor, meauring only 60mm by 27mm; The tiny module integrates 2*512MBytes DDR3 SDRAM and 8GB EMMC; It uses two 0.4mm pitch 40-pin board-to-board male extension connectors to bring out most hardware peripheral signals and GPIOs from the CPU.
