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 4 click 2 3 4. Essential features The TPCIC6A595 chip combines an 8-bit serial-in, parallel-out shift register with an 8-bit D-type storage register. On the input side, Expand 4 click uses a SPI interface, with few additions. The CLR IN pin will clear all input shift registers when held low. The EN IN pin set all drain outputs to OFF when Turn the board upside down so that Turn the board upward again. Make sure held high. The CS pin provides the impulse the bottom side is facing you upwards. to align the headers so that they are for shifting the data from the shift to the Place shorter pins of the header into the perpendicular to the board, then solder the storage register. The outputs are open-drain appropriate soldering pads. pins carefully. transistor with continuous sink capability. 1. Introduction 3. Plugging the board in Expand 4 click carries TPCIC6A595, a power click logic 8-bit shift register. Its intended for Once you have soldered the headers your use as a port expander for connecting high board is ready to be placed into the desired BOARD power peripherals (up to 50V/350-mA). The mikroBUS socket. Make sure to align the www.mikroe.com mikroBUS MOSI pin serves as the data input cut in the lower-right part of the board with from the MCU, with SCK providing the clock, the markings on the silkscreen at the and CLR IN, CS and EN pin providing additional mikroBUS socket.
