Semi-autonomous robots in the park refer to robots that can be remotely controlled when necessary when operating in a closed environment, such as agricultural robots, logistics robots, construction robots, vending robots, inspection robots, military training drones, etc. These robots are widely used in various industries, and the required computing power is not very high. RK3399 is a master control chip that is very suitable for such scenarios. The chip adopts a mature 28nm process technology; it adopts a dual-core Cortex-A72 large core + quad-core Cortex-A53 small core CPU architecture, and the main frequency can reach up to 1.8Ghz; the GPU part uses Mali-T860, which has a significant improvement in bandwidth compression technology and supports dual-screen same display and different display; it supports high-speed communication interfaces such as dual USB3.0 Type-C interfaces/PCIe 2.1, and can be connected to an external AI computing power stick to expand AI computing power; in addition, the chip also supports a variety of common peripheral interfaces, such as SPI/UART/I2C/PWM/ADC/GPIO, etc.

ElecLifeOEM has launched a control motherboard specifically for semi-autonomous robots in the park based on the RK3399 main control chip. The motherboard has stable and reliable performance and rich interfaces, which can meet the functional requirements of most park robot main control boards. The main parameters of the motherboard are as follows:
