Port Expander The Port Expander Board is an accessory board that includes a 16-bit I/O expander MCP23S17. This expander employs SPI(tm) clock up to 10 MHz. The board is ideal for expanding number of microcontroller pins on your prototype device. R245  Price ex. VAT. Weight: 12g. Stock: Out of stock [i].

Expand2 click EXPAND 2 click is an accessory board in mikroBUS form factor. It includes the MCP23017 16-bit I/O expander which features an I2C interface and clock speeds up to 1.7 MHz. Three HARDWARE ADDRESS SEL jumpers allow you to configure the board address and connect up to eight devices on the bus. The controller also supports an interrupt-on-change feature, and has optional weak pull-ups on each input. Expand2 click is set to use a 3.3V power supply by default but you can solder PWR SEL SMD jumper to the 5V position if used with 5V systems. R285  Qty: Add to Basket Price ex. VAT. Est. Weight: 20g.

Expand3 click EXPAND 3 click carries DS2408, an 8-channel programmable I/O expander that communicates with the target board MCU through a standard Dallas Semiconductor 1-Wire interface (15.3 kbps or 100kbps). The chip also has a factory-lasered 64-bit registration number, which enables multiple EXPAND 3 clicks to be connected on the same data line. For this purpose, the click has additional three pins above the mikroBUS socket. As for the socket, the onboard GP SEL jumper allows you to specify the communication pins (either OW1 or OW0, which are in place of the usual AN and PWM pins on mikroBUS). An additional reset line (RST) is also connected. The board is designed to use either a 3.3V or 5V power supply. R490  Qty: Add to Basket Price ex. VAT. Est. Weight: 20g.
