Designed for home automation enthusiasts, HVAC students and the maker community in general, the Contemporary Controls DIY products are not toys, but truly open controllers built on both open software and open hardware. Using the latest micro PCs and resident control software, these  products allow the user to create next generation Internet of Things (IoT) platforms.

The BASpi I/O daughterboards are 12-point expansion boards for the Raspberry Pi which differ only in the makeup of their outputs. This latest addition to the BASpi family has 6x Universal Inputs, 4x Relay Outputs, and 2x Analog Outputs which allows for a whole new set of applications such as FCUs!

To create a controller, you need to download the free firmware from Contemporary Controls’ website to burn on a microSD card that you will install into your Raspberry Pi. Mount one of the BASpi I/O daughterboards on top of the Raspberry Pi, power it up, and you have a 12-point BACnet/IP Sedona controller.






Flexible Input/Output – 12-points of physical I/O

• Six configurable universal inputs: analog input
(0-10V), binary input, resistance, thermistor (10kT2,
10kT3, 20k), pulse input (max 40Hz)
• Four or six relay outputs (30 V @ 2A max current)
• Two or zero analog outputs (0-10V)
• 24 virtual points communicate with a BACnet client
• 48 web components communicate with web browser

Versatile Control Device

• BACnet/IP server over 10/100 Mbps Ethernet or Wi-Fi
(802.11 b/g/n)
• Resident Sedona Virtual Machine (SVM)
• Web page configurable with a common web browser over Ethernet or Wi-Fi
• NTP server or manually-settable clock
• BAScontrol Toolset compatible:
– Sedona Applications Editor (SAE)
– BASemulator – BAScontrol Emulation on a PC
– BASbackup – BAScontrol Project Utility

  • This is long overdue. Kudos on making this product happen. Will this eventually be offered as a “package”, as in already married to a Raspberry Pi 3 like the BASPI-SYS6U6R? If so, when can that be expected to be available and what is the price point? Thanks.

      Hi Frank,
      Thank you for your interest in the BASpi!
      We actually decided to drop the packaged “BASpi System” from the product line. It will only be available until they run out of stock. We are currently working on enclosed versions of the same BASpi boards with 24V power input, DIN rail mount, and RTC. You can see these enclosed BASpi products in our BASautomation catalog on page 15 here
      If you like the system or you just want to try this new 4R2AO board before it is officially released, send me an email and I will put you on my beta users list and ship you a board you can try.
      Thank you!
