Ultra-Compact IoT Embedded Software for Mass Hardware Production “NEQTO-m” Launches with Support for STMicro’s STM32L4+ Discovery Kit IoT Node

Created upon the idea of “standardizing IoT communication software,” JIG-SAW INC. (Tokyo, hereinafter referred to as “JIG-SAW”) has completed development of a new series of NEQTO embedded-engine ultra-compact software, “NEQTO-m.” The software will become available on Monday, August 23, 2021.

”NEQTO-m” Overview
“NEQTO-m” is a new series of microcontroller unit (MCU)-embedded NEQTO engine software with a memory footprint of only 256 KB. “NEQTO-m” specializes in data transfer via NEQTO Console, and by utilizing NEQTO-m and NEQTO Console (a device management dashboard) together, it is easy to instantly build a new device management system.

3 Key Features of “NEQTO-m”
・Memory-Saving Software Design
For users who wish to further reduce the size of the available memory area in their MCU, this feature will increase the number of MCU options and reduce overall hardware cost.

・Flexible Two-Way Communication
NEQTO Flow, a feature that enables secure communication between “NEQTO-m”-enabled hardware and the user’s cloud, can be used to immediately establish a secure communication path to a designated cloud for effective data utilization.

・Reliable Data-Error Detection
NEQTO Console is equipped with a function that notifies users when communication between NEQTO Console and the cloud fails, so important issues like data loss can be automatically and immediately identified.

Example Applications
<IoT Hardware Development>
Using STMicro’s STM32 M4 microcontroller (STM32L4+) and STM32 Discovery series reference circuits, users can mass produce their own IoT hardware boards.

<Retrofitting to Equipment, Machinery, and Devices>
The built-in boards in commercial equipment (such as air conditioners, refrigerators, etc.) and the “NEQTO-m”-equipped board can be connected via UART, enabling external installation onto equipment that has already been shipped.

<Status Monitoring>
Using the “NEQTO-m” equipped board and sensors, it is possible to set up temperature and humidity monitoring for factory/warehouse spaces and status monitoring for machinery and other equipment.

Supported MCU Products: STM32L4
STMicro Developer Kit – STM32L4+Discovery Kit IoT node (B-L4S5I-IOT01A)
Additional Information:

STMicro’s STM32L4+Discovery Kit can now be purchased from anywhere in the world and used to evaluate “NEQTO-m” technology.
