SRAM/ROM memory. The module also supports rich peripheral interfaces, including USB2.0, SDIO, SPI master, I2C, I2S, IR input, UART, AUXADC, PWM, and GPIOs. These features are used to download and debug a project on EK-AI7933CLD. The front view of the EK-AI7933CLD including AI7933CLD module in Figure 1.
1) CON8 transfer USB interface to UART interface, can debug through UART, transmit, and receive a signal form PC. 2) CON8 is a USB 5V power for EK-AI7933CLD, or you can use external 5V power at J1. 3) CON6 is a USB OTG function com port.
2.2 Installing the FTDI drivers on Microsoft Windows To configure the EK-AI7933CLD: 1) Connect the EK-AI7933CLD CON8 to the computer using a micro-USB cable. 2) Check your PC is x86 or x64 system. And download and install FTDI Windows serial port driver from Here.

EK-AI7933CLD supports two types of power supply. 1) Power up with a micro-USB connector. An on-board switching regulator provides voltage of 3.3V for the EK-AI7933CLD, if the power is supplied from an on-board micro-USB connector CON8 (Figure 2). This supply can be isolated from the switching regulator using the jumpers.

Force DL mode Press SW5 to trigger strapping mode (download mode…) 4.5 RGB LED As Figure7 showed, the EK-AI7933CLD has on-board RGB LEDs (U54/U56) which be controlled by SPIM interface. Please note that ensure jumper J79 and J80 are connected before using RGB LED function If you want to cascade more RGB LED, you can connect to J78 Figure 7.
4.6 SD Card The EK-AI7933CLD reserve a SD card slot to provide user to save data into a SD card. And note that there are some registers which placed need to be reworked before using SD card. Please refer to figure.6 and switch R756 to R757;...
4.7 Extension connectors The EK-AI7933CLD provides similar pin-out extension connectors for various sensor and device connectivity, as shown in Figure.7 and described in Table 4. The board has 46 GPIOs multiplexed with other interfaces. Depending on the use case, user can configure each I/O functionality.
