BASpi-IO 12-Point BAS Daughterboards for Raspberry Pi

Product Overview

The BASpi I/O boards are 12-point BAS expansion boards (HATs) for Raspberry Pi. The I/O board, plus the firmware files provided by Contemporary Controls turn your Raspberry Pi into a BACnet-networked, Sedona-programmable controller with 6 Universal Inputs and a choice of 6 Relay Outputs or 4 Relay and 2 Analog Outputs depending on model.

All 12 physical I/O points, in addition to 24 Virtual Points are served up over BACnet/IP using Ethernet or Wi-Fi. BASpi is web page configurable over Ethernet or Wi-Fi connections. The Sedona Application Editor (SAE) is offered as part of the free BAScontrol Toolset. This programming tool is used to create control applications by linking graphical components on a wire sheet. In addition to SAE, BASemulator gives you BASpi software emulation for PC and BASbackup allows you to backup and restore your entire BASpi project to a zip file.

The BASpi I/O boards are available stand-alone, as add-on HATs for the Raspberry Pi micro PC.

Product Details

BASpi I/O board is compatible with Raspberry Pi 3 or 4 and requires a Raspbian with Desktop installation, as well as firmware files provided by Contemporary Controls. The firmware will only run if the BASpi-IO board hardware is installed on the Raspberry Pi.

The BASpi-IO models are supported by the free BAScontrol Toolset including Sedona Application Editor, BASbackup, and BASemulator as software support.
