Four, hardware design reference

1. Power design

1.YDTX-0020 voltage power supply can support 12V

2.Using RKs own RK808-D PMU, while ensuring stable and reliable work, the cost is sufficiently low

2. USB design

1.RK3399 has one USB2.0 HOST port, one USB3.0 HOST port, and one USB3. Type-c interface.

3. HDMI design

1.RK3399 chip comes with HDMI controller and supports HDMI2.0 protocol.

4. EDP Design

1.RK3399 chip comes with an LCD controller with EDP interface, EDP is a differential signal line, suitable for driving LCD screens with higher resolution. It includes 5 sets of differential pairs. Because there are many module signal definitions and the possibility of use, the eDP signal has an interface reserved on the internal front of the module.

2.The total data transmission capacity of the EDP interface can reach 21.6Gbps, which is 3 times that of the LVDS interface. It can drive higher resolution LCD screens, such as 2K and 4K screens.

5. MIPI design

1.MIPI is an alliance established by ARM, Nokia, ST, TI and other companies in 2003. The purpose is to standardize the internal interfaces of mobile phones such as cameras, display screens, and radio frequency baseband interfaces, thereby reducing the complexity of mobile phone design and increasing design complexity. flexibility. MIPI is a relatively new standard, and currently more mature applications include DSI (display interface) and CSI (camera interface).

2.RK3399 supports 1 MIPI-CSI input. Users can choose flexibly according to their needs. The data transfer rate of the MIPI interface is much greater than that of the LVDS interface.
