Serial communication
The evaluation board allows for easy serial communication with the NORA-W10 module and a
connected computer through a single FTDI, USB-to-UART IC that provides one COM port.
The COM port is connected to module UART0 through 1
kΩ
resistors, which means that multiple
UART0 signals can be connected to pin sockets J3 and J5 at the same time.
shows the function and COM port connections for each module pin.
