This kit contains two breakout boards and an interconnect cable. One breakout is installed locally on the PIEP Motherboard. The second breakout board is used as a base for stacked, remote mounted peripherals. Breakout boards are interconnected via JST 2mm 10-position connectors. Maximum current is 1 Amp at 24 VDC. A supplied pin guard should be installed over the bottom pin header on the remotely mounted breakout board. Each board measures just 1.25” X 1.25” with an installed height of just 0.25” (remotely mounted board is 0.5” in height).
