uMesh – A self-contained, battery operated ESP32 module

Part of the problem I’ve been seeing with inexpensive IoT dev boards, is that the design around the power system hasn’t been very good. Here’s my attempt to fix that. This is a battery-ready module with a proper lithium battery charge circuit, lithium battery protection circuit, power supply, and antenna, all in a 1 inch by 1 inch package. The goal is to have a tiny, inexpensive module that can immediately ...

EXTENDED BATTERY LIFE IN PORTABLE DEVICES WITH NEW LOW IQ LDO

Extending battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs, Microchip has announced a linear Low Dropout (LDO) regulator. With an ultra-low Iq of 250nA versus the approximate 1uA operation of traditional devices, the MCP1811LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often. The minimized p ...

Home Automation using Bluetooth of ESP32 with Videos (Hindi & English)

In this project, we will be dealing with the inbuilt Bluetooth feature in ESP32 Development board and try to build an application around it. https://youtu.be/zZUs_GRprpY The Bluetooth system can be divided into two different categories: Classic Bluetooth and Bluetooth Low Energy (BLE). ESP32 supports dual-mode Bluetooth, meaning that both Classic Bluetooth and BLE are supported by ESP32. Here, we will contr ...

LIBRARY MAKES ESP OVER THE AIR UPDATES EASY

Potentially, one of the great things about having a device connected to the network is that you can update it remotely. However, how do you make that happen? If you use the Arduino setup for the ESP8266 or ESP32, you might try [scottchiefbaker’s] library which promises to make the process easy. Adding it looks to be simple. You’ll need an include, of course. If you don’t mind using port 8080 and the path /w ...
