The ESP Controllers from Espressif are popular these days for IoT-based designs. The most popular ESP Boards are ESP8266-01 & ESP8266-12E/12F. These boards are the very popular amount makers, designers & IoT enthusiasts. The ready-made plug and play board is already available in the market. But the problem with these boards is they are very big in size and has power-hungry voltage regulators that may not be suitable for compact and low power projects.
This is why it is necessary to design your own ESP Board for Battery-Powered IoT Applications. In this tutorial, we will learn how to design a circuit and a compact PCB for using the ESP8266 controller. We will use the low-power LDO instead of voltage regulators & add some battery charging and battery management feature to the board.
We will not use any USB-to-UART chip like CP2102, rather we will program the device using external FTDI. By removing the extra chips and using the low-power LDOs will reduce the power consumption and makes the device small-sized. Thus the device can operate with a small Lithium-Ion Battery and charge either using USB or Solar Power. You can also use ESP8285 as an alternative and most of the points discussed here will still be the same. Watch this video till the end as it will be very very interesting.

A long awaited video, hopefully I won't get disappointed.
I'm starting to watch
Thank You & you won't get disappointed.
@@HowtoElectronics glad to hear that.
We like these type of videos so we can even support you guys by ordering pcb using your affiliated links.
Very cystal clear & informative Aabrity ma'am. Waiting for next project videos.
thank you for d information and ur voice is so sweet ❤️❤️❤️
Awesome project.
Thank you 😊
Amazing 👌
Additionally, to previous issues, your design drain 53uA from the battery all the time, for measuring purpose, consider using much higher value if measuring is needed
Every battery's voltage is measured code can be optimized to read it after certain period. What is your solution?
Helpful video
hlo sir this project is unique one can u make and give this complete PCB with ASSEMBLY for us because we will do for our project in college
Just wow
Diy esp custom bord Thanks @H2E
Two issues, first depend on working condition and battery type you may "lost" 25% of battery capacity (3.3V+0.14V= 3.44V), second if the battery doesn't have an integrated low voltage circuit, you will drain the battery to 0V and destroy it.
the processor is measuring the battery all the time. Before it drains below a certain cutoff voltage it will shut itself off (deep sleep) unless charged. I mean a code can prevent complete discharging.
what is 3.44V u calculate. U must elaborate more on your first point. Or you have an habit to comment anything?
@@trivimudbodh It is not same ,you need independed voltage control, from many reason, measuring using analog input in ESP isnt option
@@trivimudbodh Simple, check your schema, check your electronic components, and check what the specification said about voltage, and you will be available to reproduce calculation, and yes "deep sleep" drain battery to, same like LDO and other components in your circuite
@@roseat2 So are u prosing to place another mcu to measure the voltage? or digital meter or what?
Nice 👍
Could you do similar for ESP32? Thanks very useful your videos!
YES, our design is ready but need to make a video and do a lot of testing. Hopefully, I will be uploading it soon.
How to electronics! You did not even mention the size of your resulting PCB. Can you please tell that? Anyone at How to electronics can respond it.
❤
He how to electronics. What is the isze of your resulting PCB?

At switch off time charging on to battery
Nice sister
Is it possible to charge the battery and upload code at the same time?
Yes both can be done at the same time
@@HowtoElectronics Great! Waiting for the Esp32 tutorial!
"Here in london!" huh you'r in india bro.
Moved to london just a month ago
what was wrong with the circuit. was it just a footprint error or manufactoring error or schematic error?
Everything is corrected in updated schematic.
I do not see an updated schematic where is this located?
Check the link in the description. It is posted in how2electronics.com
@@HowtoElectronics The schematic on the website seems to be the same schematic on the video. Unless the video is updated as well.
The schematic is correct. Use the same component mentioned in the schematic. Since one of the component was not available with me, I replaced that component in the video.
how can shipping cost be $zero. im sure they will charge me $500 UPS express to send one free pcb 5mmx5mm and parcel will arrive in 2025 due to covid23 10th wave.
Once try for the order from the link. You will see everything as a zero for new registers only
