A6G2C Series Core Board

MiniARM Core Board

Product Data Manual

4. System Hardware Design

The A6G2C core board contains a lot of interface resources, and reliable peripheral circuits must be designed

for cooperation. This document provides the reference design method of some peripheral circuits. All circuits have

experienced strict functional verification. When designing the circuit, you can refer to the A6G2C Core Board

Reference Design Schematic Diagram.

4.1 A6G2C Core Board Interface

The A6G2C core board has integrated the power supply, reset monitoring circuit, and storage circuit into a

compact module. The required external circuits are very simple. As shown in Figure 4.1, a minimal system only

needs 5V power supply, reset button, and startup and configuration.

The A6G2C core board has a reliable independent reset circuit. You do not need to process the reset circuit.

To use manual reset, just use a button connected to the ground on the nRST_IN pin. Note that the reset signal is a

sensitive signal.Therefore, the cable routed from the nRST_IN pin to the button should be as short as possible, and

the cable should be grounded to avoid interference and system stability.

Two pins, BT_CFG1_7 and BT_CFG1_6, are used as boot configuration pins. Two-pin suspension indicates

that the core board boots from NAND Flash by default. If you need to configure SD Card to boot, just connect the

jumpers JP1 and JP2, as shown in the preceding figure.
