Hardware Description www.ti.com Block Diagram Figure 5 details a block diagram of the BOOSTXL-ULN2003 BoosterPack. The 40-pin BoosterPack header allows the BoosterPack to be interfaced with any LaunchPad in the MSP430 LaunchPad ecosystem. See ti.com/launchpad for a list of all available MSP430 LaunchPads. A row of four switches allow the user to choose between a parallel, direct-drive (8-pin) mode and a serial (3-pin) mode of control of the ULN2003A. -

D4 is connected to the signal IN4. D4 is on when IN4 is high, and is off when IN4 is low. When IN4 is high, M1_CH4 is activated – ultimately being pulled to AGND as the ULN2003A inverts the logic signal.
