The all new digital input interface for the Raspberry PI is here! The Pi-SPi-8DI has 8 inputs that can either DC or AC (Max 24 V) and are optically isolated.
The design is based on the Microchip MCP23S08 IO expander. Each MCP23S08 has 4 addresses using the same SPI Chip Select line, meaning 4 modules (32 Inputs) can be used simultaneously.
The 26 pin GPIO expansion port is duplicated on either side of the module, so more modules can be added.
Available in kit form (all SMD parts already installed) or fully assembled and factory tested.
NOTE: Accessories sold Separately
