Key Features:
- Kann das 3,3-V- oder 5-V-Netzteil verwenden.
- mikroBUS: I2C-Schnittstelle
Das Expand 2 Click Board™ ist eine Zubehörplatine im MikroBUS-Formfaktor. Es enthält einen 16-Bit-E/A-Expander MCP23017 mit I°C-Taktraten von bis zu 10 MHz für Anwendungen mit höherem Durchsatz.
IC/Module: MCP23017 Port Expander
MCP23017 is a 16-bit remote bidirectional I/O port expander with configurable interrupt output pins. The 16 I/O port bits are divided into two 8-bit ports (marked HD1 and HD2). It has I2C clock speeds of 100 kHz, 400 kHz, or 1.7 MHz for higher throughput applications.
Expand 2 Click Board™ Vs Expand Click Board™
Expand 2 Click Board™ is introduced as the sequel to the original Expand Click Board™. Expand 2 Click Board™ uses MCP23017 expander whereas the original version includes the MCP23S17 chip. The only feature that differentiates these two versions is the use of I2C communication interface, instead of SPI.
SMD Jumpers
Expand 2 Click Board™ features four zero-ohm SMD jumpers. The PWR SEL is used to select between 5V or 3.3V power supply, and three hardware ADDR SEL allows the user to select the device address.
