Introduction
Raspberry Pi is a widely used Arm development board and the Digilent Pmod interface is used to connect low frequency, low I/O pin count peripheral modules to host controller boards. This expansion board is a bridge to connect all kinds of Pmods to the Raspberry Pi. The board also provided much more useful features such as ADCs, 5v I/Os and Coprocessor, see specifications section for more details.
Specifications
- 2 Pmods Interfaces (All I/Os are remapable)
- 8 ADC inputs (Up to 1Mhz Sampling rate)
- 8 5v Tolerant I/O (All I/Os are remapable)
- Onboard Arm Cortex M3 MCU (Coprocessor, STM32F103RBT6)
- Altera CPLD (EPM240T100C5)
