BASpi-IO Compatible with Raspberry Pi 4!

Following the announcement of the Raspberry Pi 4, BASpi customers have been asking us about compatibility with the Pi 4. The good news is YES, both versions of our 12-point expansion board will fit and function properly with the Rpi4.

The Raspberry Pi General Purpose I/O Pins (GPIO) pin-count and layout remains unchanged between the Raspberry Pi 3 and 4. Mechanical interconnect locations are unchanged as well. This means the BASPI-IO6U6R daughterboard with six universal inputs and six relay outputs, as well as the BASPI-IO6U4R2A with six universal inputs, four relay outputs, and two analog outputs will mount and operate seamlessly with either Raspberry Pi 3 or 4 to create a BACnet-networked, Sedona programmable controller with industry standard I/O.

There are some advantages to using the Raspberry Pi 4. The Pi4 has two to four times more RAM memory than the Rpi3, offering 1, 2 or 4 GB of DDR4 RAM options (versus the only 1 GB DDR2 option on the Rpi3). The Rpi4 also has Gigabit Ethernet, 802.11ac Wi-Fi, and Bluetooth 5.0 for communication. The combination of these new features paired with our BASpi I/O HAT produces a next generation controller which allows parallel programs to operate concurrently giving more power to users. Both BASpi-IO boards are supported by the free BAScontrol Toolset which includes the Sedona Application Editor – used for graphical programming of sequences of control operation, BASbackup – project archiving utility, and BASemulator which provides controller emulation on your PC!
