06. NEQTO Bridge Digital IO Board

Overview

The NEQTO Bridge Digital 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 Digital 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.

For information regarding the "Method for inserting and removing a module", refer here.
