Key Points for Designing Baseboard Circuit This product supports UART, I2C interface control; if user s UART, I2C voltage is 5V, it needs to be converted to 3.3V RTC design The module RTC_POWER needs to be separately connected to the power supply branch that will not be cut off, in order to guarantee RTC time continuity Differential line, high-speed line impedance Differential Line High-speed Line 90 ohm 100 ohm 50 ohm USB LVDS SDIO RGB888 BT656/BT601 I2S 5.
