Yidiantong newly launched the YDT-0020 development board based on Rockchip RK3399
1. Product overview
Product description:
YDTX-0020 is a development board based on Rockchip RK3399, which is independently developed, produced and sold by Shenzhen Yidiantong New Technology Co., Ltd.RK3399 chip adopts big.LITTLE size core architecture, dual Cortex-A72 large core + four Cortex-A53 small core structure, greatly optimized for integer, floating point, memory, etc., in terms of overall performance, power consumption and core area. All have a revolutionary improvement. The GPU of RK3399 uses the quad-core ARM new generation high-end image processor Mali-T860, which integrates more bandwidth compression technologies: such as smart superposition, ASTC, local pixel storage, etc. It also supports more graphics and computing interfaces, and the overall performance is better than that A generation increase of 45%.
RK3399 has rich interface expansion capabilities. HDMI2.0, MIPI-CSI, MIPI-DSI, PCIe, DP1.2, eDP, USB3.0, and 42Pin headers are reserved (including: 8-channel I2S, ADC, I2C, SPI/UART, GPIO, LINEOUT, SPEAKER ). Support 2.4G Hz/5G Hz dual-band WiFi, BT4.1 and Gigabit Ethernet, PCIe can also extend the LTE module to achieve 4G communication. With 4 high-performance display interfaces such as HDMI2.0, MIPI-DSI, eDP and other display interfaces, it has powerful display performance and can realize dual-screen display. It has obvious advantages for high-end display fields such as VR smart devices.
Scope of application:
Rockchip RK3399 chip supports Android\Linux system, complete software support, suitable for enterprises to develop high-definition display commercial display advertising machines, self-service vending machines, education terminals, POS machines, face recognition, etc., which can lower the R&D threshold and shorten the product development cycle . Application areas: Commercial display advertising machines, smart POS machines, self-service sales
Freighters, touch all-in-one machines, smart robots, medical and health equipment, gaming equipment, etc.

Four, hardware design reference
1. Power design
1.YDTX-0020 voltage power supply can support 12V2.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.
