: The SoC supports UART for debugging and programming, as well as I2C, SPI, and PWM for peripheral control. Firmware Protection Verified security includes a 32-bit customized key for firmware encryption and an on-chip 64-bit unique ID

The chip is widely "verified" in consumer electronics, including:
