EK-7933CT mounted MT7933CT is a highly integrated IoT module that features an ARM® Cortex-M33 application processor, a low power 1T1R 802.11a/b/g/n/ac/ax dual-band Wi-Fi subsystem, a Bluetooth v5.0 subsystem, a Power Management Unit (PMU) and a audio HiFi4 DSP. This SoC is based on ARM® Cortex-M33 with floating point microcontroller (MCU) including SRAM/ROM memory. The module also supports rich peripheral interfaces, including USB2.0, SDIO, SPI master/slave, I2C, I2S, IR input, UART, AUXADC, PWM, and GPIOs.
Cadence Tensilica HiFi4 Processor with 600 MHz clock speed
Audio Codec with 2 ADC and 1 DAC channels
Embedded 256KB SRAM memory
Supports Voice Activity Detection(VAD) and Keyword detection
On-board headhone jack for external active speaker
SD card slot could provide user to save data into a SD card and this controller fully support the SD memory card bus protocol as defined in SD Memory Card Specification Part 1 Physical Layer Specification version 2.0.
EK-7933CT should plug in a FTDI debug board at U14. Within this FTDI debug board to make UART signal transfer to USB signal. This debug board also provide a Micro-USB connector to link to with your PC with USB cable.
