Product Overview
SMLS 3A7A H Module is designed according to PICMG COM Express Module Base Specification Reversion 2.0 Type 6,CPU The 3A6000 processor adopts four high-performance 6-emission 64-bit LA664 processor cores, and supports multi-thread technology (SMT2) to achieve four cores and eight threads, and is expected to be 2.5GHz (TDP, subject to the final specifications of the original factory). Equipped with Loongson's new generation of autonomous bridge chip 7A2000, integrated high-performance GPU disy function; 8GB of on-board DDR4 memory is standard. Module support 2 Gigabit network,32 PCI-E,8 USB2.0,4 USB3.0,6 serial ports,3 SATA3.0 and other I/O expansion; Supports three disy outputs: one HDMI/VGA port and one dual-channel 24-bit LVDS (HDMI optional) signal.
The module size is 95*95mm, typical power consumption is 35W (TDP), and the default is 100percent domestic. Module definition is fully compatible with JDA's previous generation SMLS 3A7A B/C/D/E series COM-E module, using full table attached design, with high performance, high localization, high stability, high reliability and other characteristics, can be widely used in national defense, government, scientific research, medical, electric power, communication, transportation and other fields

Motherboard screen printing rules
How to identify jumper, interface first pin?
a. Observe the plug, the text mark next to the socket: usually use "1" or bold line or triangle symbol "△" to indicate
b. Look at the pad on the back, usually the square pad is the first foot
c. The A1/C1 pins of the 220Pin te-to-board connector are located at the diagonal opening of the connector as shown in the following figure. Pin B1/D1 is on the opposite side of pin A1/C1
