RESET
Support hardware reset.
BOOT
Pull down when firmware upgrade, pull up or NC when normal working.
UART
The module’s UART is a standard four lines interface (RX/TX/RTS/CTS). Its baud rate
can be selected via UART AT command.
Support hardware flow control.
Support speed of up to 4Mbit/s.
Uart0 can be served by the DMA controller.
I2C
I2C interface supports standard mode (100kbit/s) and fast mode (400kbit/s). The I2C
work as either master or slave mode.
GPIO
Floating level on input signals will cause unstable device operation and abnormal
current consumption. Pull-up or Pull-down resistors should be used appropriately for
input or bidirectional pins.
USB
Support USB 2.0 full speed mode.
