Sequent Microsystems Exceeds Funding Goal on Kickstarter For Its Remarkable Home Automation Solution

Raspberry PI Mega-IO Expansion Card” For Home Automation Offers a 12-Bit DAC, 8X ADC, 8X Relays, 8X Opto-Inputs, And 6X GPIO

Cupertino, CA, USA – September 22, 2017 – Sequent Microsystems, a tech startup from Cupertino, CA has launched a Kickstarter campaign for a new I/O expansion card for the Raspberry Pi platform. Loaded with inputs, outputs, and relays, the card targets the booming DIY  Home Automation market. According to the KS page, the card attempts to integrate as many Home Automation functions as possible into the small, credit card format of the Raspberry Pi.

Shipment of these cards is expected by March 2018 and the company has already exceeded its Kickstarter campaign goal due to the overwhelming response.

“Basic Home Automation functions like HVAC, security, irrigation, and soil humidity detection usually require multiple I/O’s, relays, analog inputs and a tangle of cables in between”, says Mihai Beffa, Sequent’s CEO. “We integrate all these functions into a single, compact an affordable stackable platform”.

The Mega-IO card features eight relays, eight 12-bit A/D channels with sample rate of up to 1 Mbps, one 12-bit D/A output, eight optically isolated inputs, four open collector outputs, and six general purpose I/O’. With a MSRP of $39, the first tier of the Kickstarter campaign of 200 pieces at an introductory price of $25 has been exhausted within a few days. As of today, a limited number of  four-packs which can support all the functions of a smart home is still available for $96, and a limited number of Mega-IO cards are also available for $29.

The key specifications of the Raspberry Pi Mega-IO Expansion Card include:

  • 8x relays rated at 10A/250V (the card itself is rated at 5A/48V)
  • 8-channel 12-bit ADC
  • 12-bit DAC
  • 8-channel optically isolated inputs
  • 4x 16V/140mA open collector outputs
  • 6x GPIOs
  • 23x free GPIOs carried through from Raspberry Pi
  • Fully configurable interrupts

The Mega-IO card comes with a Command Line interface which can be used to access all the card’s functions. Programming examples in Javascript and Node-RED, a drag and drop visual tool made by IBM for wiring the IOT,  are available for download from the Sequent’s website. CODESYS and Python drivers are under development and will be available soon. 

The Mega-IO has been nominated a “Project we Love” by Kickstarter and with a few days to go it has exceeded the funding goal by more than 150%.
