DECADA Embedded - Microcontroller-Class Devices that Communicates with DECADA Cloud | Singapore Government Developer Portal
Have feedback? Please

Overview

DECADA Embedded (formerly known as MANUCA) are a family of microcontroller-class devices that can communicate directly to DECADA Cloud.

Microcontroller-class devices are prevalent in an IoT network, as they are low in cost and extremely energy efficient at scale. Depending on the hardware specifications, they can play the role of a node and/or a simple gateway. These resource-constrained devices run off kilobytes to megabytes of flash memory and RAM, which requires a different approach to software development.

What is DECADA Embedded?

As part of the Singapore Government Tech Stack, DECADA Embedded provides software reference designs to hasten development time. By extending the reference examples, developers will be able to add their custom application logics for their use cases, while not having to fret over how onboarding and communication are done with DECADA Cloud in the software.

Why Should DECADA Embedded be Adopted?

Organisations who wish to connect their microcontroller-class devices to GovTech’s IoT Cloud (DECADA Cloud) will be able to cut software development time significantly when they reference our open-sourced examples. We provide the following RTOS reference examples, which can be compiled and run straight out-of-the-box:

  • MbedOS: https://github.com/GovTechSIOT/decada-embedded-example-mbedos
  • Zephyr: https://github.com/GovTechSIOT/decada-embedded-example-zephyr

How Do You Use DECADA Embedded?

Refer to README.md of the respective decada-embedded-example-* repository.

Success Stories

DECADA Embedded Gateway and Sensor Nodes
The team uses DECADA Embedded as a starting point to design and build gateways and sensor nodes.

SafeEntry Gateway
SafeEntry Gateway prototypes were based off decada-embedded-example-mbedos, which gave developers the speed to iterate the business logic, instead of handling cloud connection logic.

TraceTogether Upload Station
A Decada-embedded device that uploads contact tracing data from the trace together tokens for covid positive patients. Featuring remote firmware update capability, this device enables nurses to spend less time uploading contact tracing data and focus on what they do best - caring for patients.

Sport Singapore and National Parks Board (NParks) used IoT devices based on decada-embedded-example-mbedos software for their smart lighting works.
