Being on the quest for a triangularization process for my BLE ankle-monitor, I specifically ordered these ESP32s due to their external antenna.I was previously using dev-boards with an on-board antenna, and the Wifi and Bluetooth range left a lot to be desired. In comparison, these new ones proved very capable in that regard, as their antenna allows them to detect low-energy Bluetooth beacon even farther. They also offer a more robust connection to my Wi-Fi thanks to the external antenna.Be sure to be careful with the external antenna, as those type of "laptop" antenna connectors are known to be fragile.They are able to run ESPresense out of the box, and can then be integrated to Home-Assistant with the MQTT-ROOM component.

If your buying this and are not tech savvy I will quickly go over the few things you need to know.FIRST: your most likely gonna need to download a driver from silicon labs website, a simple Google search will guide you to the correct driver. It will be a zip file, so you will have to unzip it. Depending on your computer, it may not let you download the driver completely at first, however, I used chat gpt and never even used youtube or Google, and the chatgpt app walked me through the process to override it and it was simple (and I'm not tech savvy).SECONDLY: you'll likely have to download the necessary libraries and use the board manager in the ardunio IDE to make this work with your ardunio program, this is also very simple, chatgpt or Google can walk you through this.THIRDLY: this is a big one, the way you load code on the ardunio is exactly how you load them on this, simple take your sketch and upload it, you MUST have the proper micro usb cable that deals with data transfer and not just charging capabilites. The major difference between how you upload codes to this compared to ardunio, is that you need to put it in bootloader mode, the way to do this is you push and hold the boot button, then while holding the boot button you push the EN button and release it, THEN release the boot button, HOWEVER!! These things are notorious for not working when you do this. This will drive you crazy but there's a way to deal with it and this is why I took 1 star off the review. You can push and hold the boot button, then while holding down the boot button, you can click upload sketch, and keep holding the boot button until it finishes loading the sketch. There is other ways to make the bootloader work, using capacitors and stuff, I won't explain it Google and chatgpt have the answers. Your gonna need the blynk library as well from your ardunio libaries, if you decide to use blynk. I used it and it works fine I had a friend log into my account on blynks and he was turning on and off my lights from over 200kms away from my house with no lag time at all.FOURTHLY: this only outputs 3v, so if your circuit needs are above 3v, say like an ardunio relay that takes 5v or some other component or sensor, you'll want to consider a DC-DC converter, their cheap and can step up the voltage from 3 to 5, some step up input voltages of 3-35v input to 5-45v output. Then you just daisy chain the esp32 output into the input of the DC to DC convertor, then the output of the converter to the components or circuits you desire.All in all really fun, really cool little project. Works well, the antenna doesn't feel like you can push it down in place but trust me just line it up and give it a little push and it will go on the connector on the board. Just needs to be lined up perfectly flat before you push it down, would highly recommend this, and if your not sure how to write code for it, ask chatgpt for codes to help and they work just fine.

I received an ESP32 microcontroller on a development board, and accompanied by an external antenna for wireless communication. The central feature of the development board is the ESP32 microcontroller, which can be programmed to perform a variety of functions, including monitoring devices and responding to these inputs by sending signals to other components. This can occur through wired connections or through wireless communication. Anyone who has worked with microcontrollers before should be able to work with this ESP32, and there are several programming software packages available to do this, including the popular Arduino IDE. If you are new to microcontrollers, there are no instructions included with this item, and you are likely better served by obtaining a beginners kit, along with a manual, and it may contain an ESP32 or other similar microcontroller. The development board arrived nicely packed in an antistatic bag, and accompanied with foam padding to prevent damage to its pins. This development board seems well made, with good quality soldering. Its nice that this board is configured similarly to other development boards using the ESP32 microcontroller. It can fit on a variety of breadboards, allowing one to easily make electrical connections to its many I/O pins. Overall, a nice ESP32 development board to set up your electronic projects.

So at first I had a little bit of trouble getting this set up. My computer could not recognize the board, and therefore the Arduino IDE couldn't find it either. The Arduino IDE does have entries for ESP32 boards but you have to select it for it to then download a bunch of stuff and then you should be all set.I was able to then successfully connect to the ESP32 board and install a hello world type of application and everything worked perfectly. A very nice device. I do wish the microUSB port was a USB-C port instead but I had a microUSB cord laying around. If you don't have one, you will need one.Comes With:- one ESP32 development board- detachable antennaPros:- works perfectly- an official ESP32 deviceCons:- a quick start guide would be nice

Some Pros and Cons of this ESP32General:Is is not listed in the description but this has a Micro USB port on not (Not a USB C) and requires that you load CP201x Virtual COM port drivers before you can use it on a windows machine. (You will have to hunt for drivers on the web)The Unit is a ESP32 S which has the same pinout as WROOM 32Pros:Nice packaging, ensures there are no bent pins etc.Does give way better range than the cheap ESP32s I was using before. (Am getting about 30 Meters Open Air) vs 10 Meters with the other ones I haveCons:Does not have any silkscreen identifying the various pins so had to do a bit of sleuthing to figure out the pin out.It is an ESPS Not an S2 or S3 so there are newer and more powerful versions out there which use less energyThe external antenna connector on the antenna itself is very brittle and will likely only give you 1 or 2 attachments before it breaks off, so you need to take care.
