05. NEQTO Bridge IO Board

Overview

The NEQTO Bridge IO Board is an evaluation extension board for easily connecting peripheral devices to the peripheral interface of the NEQTO Bridge Module, such as UART, SPI, I2C, and GPIO.
Hereinafter, "NEQTO Bridge IO Board" is called "IO board" and "NEQTO Bridge Module" is called "module".
By identifying the connected IO board, the module automatically enables the function unique to the IO board.
neqto.js' nqEx Object is used to control each interface. All interfaces are disabled by default, so enable them as needed.
