I/O Hub 1 to 6 Expansion Unit (MEGA328)

I/O Hub 1 to 6 Expansion Unit (MEGA328)

Description

PbHUB, is a expander for singel-bus GROVE PORTB(Black port on M5GO Base). 1-to-6. PortB can be used as GPIO and analog in two data lines connected to GPIO36 and GPIO26 on ESP32. Same as PaHUB, it provides a solution for mutiple device control by PORTB. With PbHUB each of the IO can be configurated to input, output and analog in as you like. Unfortunatly this Unit is unnested. It is build with a MEGA328, with a simple driver firmware inside.

The I2C address of this unit is 0x40(Changable by resistors).

Notice: Please pay attention to the channel order while programing
