Arduino Shield Connectors - ARM MPS3 Technical Reference Manual

A.2

Arduino Shield connectors

Connectors on the MPS3 board provide two Shield expansion interfaces. Each interface provides 16
digital I/O and six analog I/O.
The Peripheral Module interface (Pmod) connectors share some of the Shield connectors and are wired
in parallel with them. Interface Pmod0/1 shares some signals with Shield 0 interface, and Pmod2/3
shares some signals with Shield 1 interface.
The MPS3 board supports simultaneous use of Pmod and Shield expansion but you must take care when
driving the shared signals.
Shield 0 and Shield 1 interface connectors
The following figure shows a combined diagram of the Arduino Shield 0 and Arduino Shield 1 interfaces
on the MPS3 board.

Connector J25 (Shield interface 0)
Connector J33 (Shield interface 1)
Connectors J25, J26, J27, J29, and J30 form the Shield 0 interface.
Connectors J33, J35, J36, J37, and J39 form the Shield 1 interface.
