ARM MPS3 User Manual

2.16 Arduino Shield and Pmod interfaces
The MPS3 board supports peripheral development by providing two Arduino Shield interfaces and, as an
alternative, four Peripheral Module (Pmod) interfaces (Type 2A/3/4 support).
Overview of Shield and Pmod interfaces
The following figure shows the two Shield interfaces, and the four Pmod interfaces where the FPGA
design implements an SPI controller that drives the 12‑bit ADC.
