- Page 2 High current, high side switching for Arduino Introduction The Logos Electromechanical ARD-SRG-IPS4X4 16 channel high current shield is designed to enable users to switch DC loads up to 5A at up to 30V with no heat-sinking. It uses four International Rectifier IPS6044 four channel fully-protected high side MOSFET switch ICs.

Page 3: Board Overview
Each of the four IPS6044 chips houses four channels. Each IPS6044 draws its power supply from a pair of pins on the main connector and switches it to Figure 2: Board Layout © 2010 Logos Electromechanical CC-BY-NC-ND 3.0... -

Assemble the fourth connector as you did the second and the fifth as you did © 2010 Logos Electromechanical CC-BY-NC-ND 3.0... - Page 10 Connector 1 is on the left end of the cable. Figure 5: Daisy chain cable Certain other Logos Electromechanical parts also use shift registers compatible with this shield – see the product page for which ones. They will have expansion connectors compatible with the eight pin connector on this shield.
