2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 EXPAND 3 click 2 3 4. Essential features Each DS2408 IC has a factory-lasered 64-bit registration number. Combined with the standard Dallas Semiconductor 1-Wire protocol it uses to communicate with the target board MCU, the registration number enables multiple devices to reside on the Turn the board upside down so that Turn the board upward again. Make sure same data line, each one with a unique ID. the bottom side is facing you upwards. to align the headers so that they are To connect multiple Expand 3 clicks , use Place shorter pins of the header into the perpendicular to the board, then solder the the additional three pins positioned above appropriate soldering pads. pins carefully. the mikroBUS socket (VCC, OW, GND). 1. Introduction EXPAND 3 click is an accessory board in mikroBUS form factor. It includes an 3. Plugging the board in 8-channel programmable I/O expander click DS2408 that communicates with the target Once you have soldered the headers your board MCU through a 1-Wire interface (15.3 board is ready to be placed into the desired BOARD kbps or 100kbps) The onboard GP SEL jumper mikroBUS socket.
