I/O Hub 1 to 6 Expansion Board Grove I/O Interface forBlockly Development IoT MEGA328 Module

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 Notice 1 Please pay attention to the channel order while programing 2 Not all M5Units with PortB Black is able to extended by PbHUB PbHUB can only apply to basic single bus communication like digital read and write analog read and write which is implemented by I2C protocol MEGA328 inside The mechanism of PbHUB as an extension of PortB which inplement the single bus data transfer is using the resource on Mega328 include GPIO AD DA ports to inplement the functionality of digital read and write analog read and write So there must be exceptions in which case a PbHUB is not a option For example PortB M5Unit like WEIGH HX711 inside whose communication protocol is applied more than just anglog read instead with a timing order In that case PbHUB can t be helpful dirving those device or sensor Product Features Single Bus GROVE PORTB ExpanderTwo Leigo compatible holes1 To 6Package Included 1x PbHUB Unit1x Grove Cable Code Driver firmware PbHUBTest code PbHUBprotovol type I2Caddress 0x61Set oneLED Color
