Thanks a lot. I spent many hours trying to load a program to esp01 using esp01-programmer without success. When i putted the switch like you shown everything worked at first try.

VERY instructive. It was easy to make choice of module-type decisions. Thank you.

I was so stuck setting up this esp-01 and this video is a breath of fresh air.

Nice video. I needed to set up a network of sensor modules throughout my home, and I wanted to make them small and inexpensive. I used an ESP-01 on a 170 hole breadboard for each one and that was perfect. I programmed the ESP-01s with a NodeMCU which was very effective for that.

You, Sir, are amazing. Thank you.

thanks for the tip with 3.3V for CH_PD

Really clear fabulous video thank you

Do you happen to have any tutorials on how to use an 01 with a single relay board?

Thanks for making this video. I bought a bunch of these because they were cheap and I figured you could put them all over the place in a network, maybe as slaves to a nodemcu device. The configuration of these modules is kinda stupid though because you have to adapt it no matter how you want to use it. That big connector takes up a lot of space. Maybe the answer is to remove the connector altogether.

I have a few of these and was thinking they might be good for small IoT needs. Things like a window opening or even a mailbox alert tool. Question, since they are so minimal do you get a good power savings compared to a Wemos D1 Mini? Would this device be better for battery powered projects? If you toss in deep sleep would the be a good idea?

With I2C, you can do a lot of work with peripherals, like I/I expanders, ADC/DAC, LED drivers, and more...

I believe these have their place Brian. I just received 6 at a total cost of €11 shipped so sub €2 which in my book is negligable. I also ordered a USB to serial ESP01 programmer with the switch already in place, about €2.50 shipped IIRC. For embedded projects that focus on the ESP8266's WiFi features as distinct from DIO applications they are great. This is what I use in my smart smoke alarm Pushbullet notifier as it is actually easier to fit this in a small space, even compared to a D1 Mini with no headers. Having good success using custom fields in the WiFi config (some stuff persists reflashing! SPIFFS perhaps making debugging frustrating) for super portability and sharability so exploiting some amazing features of a tiny chip on a ready to go module for

Hey Gary, thanks so much for taking the time to comment! Yeah I agree that they are useful for the kind of projects you describe, just personally I think it's more convenient to work with a development board. I think the video might have come across a little negative on the board, I didn't really mean it like that, it was more that I would recommend the development boards over the ESP01. I was actually only thinking on the way to work this morning that I didn't make it clear that functionally from a WiFi point of view these are the same chip, I'll try clear that up in the next video I do on them. ( The project I mentioned at the end is where I'm controlling LED lights from a webpage) Price wise, an ESP-01 is roughly $2 delivered from Aliexpress while a clone Wemos D1 mini (which I have never had any problems with) is about $3 delivered. Personally for the sake of a $1 I would prefer the D1 mini as i mentioned I power most of projects through USB and being able easily program it and have the serial monitor available is a big bonus too. I take your point on size, but I as mentioned on the video I was surprised that it isn't that much smaller than a Wemos D1 mini. Yeah, the fact that these chips can do any of this is still crazy to me! How are you going to detect the cycle is done? I might do the same myself :)

Brian Lough I too keep a good stock of D1 Minis and there is so little difference in price, that's a fact. I agree they are so simple and a really good compromise in size, IO and power pins, maybe my inner environmental manager tells me it's a waste to use a US to serial converter once and often a half dozen IO never! For the washing machine I was thinking along the lines of a switching power supply matched up with an esp8266 and a mini current transformer on the power line to the door switch. This drives the indicator on the door at 220Vac so the current transformer means no dangerous ac potential on dev boards. In this case I have a few 5v power supplies and a can't help thinking voltage divider on the analog pin of a D1 Mini is the winner on account of the on board LDO reg and analog channel.

Have replaced the flash with 1MB and use 4 gpio pins with Home assistant. Small module to drive RGB analog and digital RGB strips. Make sure use pullup resisters on the RX, GPIO0,and GPIO2. Must be high on boot. Happy Home assistant developing.

Have you have found a better way to use it?

Can we use micropython to code esp01?

Where are the names for the libraries for this board?

What's the difference between and the larger ESP8266 with micro USB port?

You only need to hold GPIO0 low while booting to enter program mode, so a momentary switch held down while you plug it in would work to. Also you can use the Rx and Tx pins for GPIO as well so up to 4 digital GPIOs. No analogue in though unfortunately.

I quite like the ESP-01. If you think of the Wemos as equivalent to an Arduino Nano then the 01 is kind of the ESP version of the ATTiny85. A lot of power in a relatively small space. Hope you enjoy thinking up projects to use them.

+Arthur Pearce you can tell by looking at them. The fake ones tend to have a more square PCB. Honestly though I use the fake ones all the time and never had an issue with them. If you had one your not sure about if you wanted to post a picture of it I could tell you They are about half the price for a single unit delivered

Good video, but much has changed , Really like the adapter hack, Dremel tool will make cuts easy (to make adapter smaller). Some where I saw a video of someone soldering wires to surface mount chip and ended up with 6 io pins. Small boxes are easy to think outside of. Why pay extra for a built in programmer that you may need only once? Suspect you can get as many io's as any other esp8266 chip based board.

Nice but I just want to make a simple door indicator so when my front door goes open I get a message on my phone so when in the workshop I know I have a delivery as I am new to all this it has to be as simple as posable thanks for the video very good

What if only the RED LED works? Then the blue sometimes light up, but in a faster blinking way, then goes off.

In newer models of the EPS-01 the built-in LED is set differently. In the Arduino IDE you could try changing the 'builtin led' option under Tools to 1 or 13 or 16.

Muhammad, in case you are still waiting for an answer, it is GP00 that should be grounded to go to load mode. I also pull-up EN to 3.3V.

I think the module is much more suited for usage with other components and not as stand-alone.

The newer ESP-01 boards have the blue blink LED on IO2, not IO1. In addition the programmer is useless and has several design flaws: lack of program switch and reset button. On the signal lines there is +5V present, which is out of the ESP8266 specifications! The reason for this is that the USB-to-serial converter chip CH340G is powered by +5V. They should have used the 3V3 from the on-board regulator.

Followed instructions to the letter, no error, no Blinky Blinky :(
