Key Features utilised:
• Integrated low power 32 – bit MCU
• WIFI 2.4 GHz support WPA/WPA2
• Deep sleep power <10 uA, power down leakage current <5uA
• Wake up and transmitter packets < 2ms
• FCC, CE, TELEC, WIFI Alliance, and SRC certified
• SDIO 2.0, (H) SPI, UART, I2C, I2S, IR Remote Control, PWM, GPIO
Based on the above features the microcontroller was ideal for easy and reliable WIFI connection
set up. The less than 2 milliseconds wake up time from the low power mode allows for low
power consumption and to only wake up the controller for sending when the time of flight
sensors transmits information through the I2C connection.
