DC-DC Power Module 25W

Overview

This Power Module is a small size 5A 350KHz 25V Buck DC to DC Converter.
It can convert any DC voltage between 3.6V-25V to a selectable voltage from 3.3V to 25V.
You can choose 5V direct output voltage with the switch or adjust the output voltage by the blue&white resistor.
It is convenient for you to choose three different interfaces of output.
The Ovout interface can output the original voltage of input.so that can be used as the power of other module.
The ON/OFF button on the board can be pulled high to turn the converter module on and low to turn it off.

Controlling a power strip with a keyword spotting model and the Nicla Voice
Controlling a power strip with a keyword spotting model and the Nicla Voice
November 24, 2023

As Jallson Suryo discusses in his project, adding voice controls to our appliances typically involves an internet connection and a smart assistant device such as Amazon Alexa or Google Assistant. This means extra latency, security concerns, and increased expenses due to the additional hardware and bandwidth requirements. This is why he created a prototype based on an Arduino Nicla Voice that can provide power for up to four outlets using just a voice command. Suryo gathered a dataset by repeating the words “one," “two," “three," “four," “on," and “off” into his phone and then uploaded the recordings to an Edge Impulse project. From here, he split the files into individual words before rebalancing his dataset to ensure each label was equally represented. The classifier model was trained for keyword spotting and used Syntiant NDP120-optimal settings for voice to yield an accuracy of around 80%. Apart from the Nicla Voice, Suryo incorporated a Pro Micro board to handle switching the bank of relays on or off. When the Nicla Voice detects the relay number, such as “one” or “three," it then waits until the follow-up “on” or “off” keyword is detected. With both the number and state now known, it sends an I2C transmission to the accompanying Pro Micro which decodes the command and switches the correct relay.
