TF Card Interface

The TF card can be used as a system storage or an external storage. When it's used as a system storage, you had better choose the ones with storage space larger than 8GB. When it's used as an external storage, you can choose the ones with storage space up to 128GB. When the TF card is inserted into the TF card slot , the device will be automatically recognized by the system.

The TF card interface pin specification shows below.

More details about 40-pin Header

  • Pin#12(GPIO2_D2) is also the sleep pin of PMIC RK805. Be careful when you try to control it.
  • Pin#3 and Pin#5 are only for I2C communication.
  • Pins marked with color orange are designed for debug console.
  • SPI: x1
  • I2C: x1, I2C1
  • UART: x1, UART1 and UART2
  • USB: USB20DM(Pin#16) and USB20DP(Pin#18)
  • PDM: x1
  • I2S: x1, I2S1
