µParticle Interface: Connectors etc.

µParticle Interface

Board to Board connectors provide the flexiblity to combine the various modules of the µParticle system such as µPart Boards and µSensor Boards The connector used on all Particle devices is ERNI's 6 pin MicroStack 0.8mm connector There are no male and female connectors, all connectors can be stacked togehter (here is a eagle library file for this connector):

• Pin number see picture below

µPart connectors share the same concept of the Particle Connector but (because they only have 6, not 21 pins) are reduced in function.

The connector is used to

• provide the connection between the µPart board AND one of the µSensor boards
• provide the interface to program/flash the processor of the µPart by using the µProgramming adapter and a programmer
• provide the interface for configuration using the µConf adapter
• provide the interface between the µPart board AND the (µProto board) for interconnection
• The following combinations are possible. Subsets of the below named combinations are also possible (e.g. particle AND breakout)

The µPart Interface lines are used for communication of I/O signals (digital and analog), status and control lines (e.g. reset) and for power supply (gnd and V+). The following table gives an overview over the pin assignment for the various boards. Note: many of the lines are multiplexed:

I: Input line
O: Output line
S: Supply line
C: Control line
D: Digital line
A: Analog line
B: Bus line

INTx: Interrupt lines (1 mandatory, 2optional)
I/O: digital I/O lines
A: Analog lines
/RESET: System reset line (1 line)
TX,RX: Serial Interface line (2 lines)
PwrSens: Power lines for sensors attached to the µPart Connector

*5: Mandatory functions for that line. Must be provided by all core boards
