Elecrow ESP32-5.0 Inch HMI Display

hi I'm DJ Ware on this episode of the Cyber Gizmo I have something to review well I don't know you can't really call this a review uh I received this as a free product to take a look at and you can't really do a review on something like that but so first of all let me tell you what this is this is a an esp32 display this is a five inch display and it uses HMI it has a touch screen and on the back you have you have an actual processor it's right there the esp32 is right there you have a number of these are this is these two right here are gpio D pins this one uses something called a it doesn't have the traditional you know the the pins that are you know like the 30 pin or or the 40 pin gpio headers that you normally see like on a Raspberry Pi but it uses this and you you just it's keyed so you plug it in and then you can plug this into your project board and do whatever that you want to do with it this one over here is a little bit different it's more of a it's more of a it has four looks like four pins in it so it's meant to take a flat connector this is your uart so this is your serial connection you have two buttons here one is the this outer one is for boot this is for reset then you have a USBC connector here this is your power and your upload Port this is a battery connection this is the TF card or SD card if you prefer and there is a speaker connector here so uh let's talk a little bit more about the specs for it so we've talked about some of the pins that are on it it is the processor that makes this up is a esp32 S3 Dash W room and this is the one and for our eight version of that processor both the seven uh ver inch and this one the five inch both have that higher end processor they they make this board and 2.5 all the way up to seven inch but when you go down from this one they you get lower performance processors so this is a dual core a 32-bit this is an lx6 uh it is it is running at 240 megahertz uh the display is 800 by 480. this is compatible both with Arduino and there is a library called uh the lvgl and we'll talk more about that so it is compatible with both of those standards and there is also Wi-Fi and Bluetooth on the board on this board now now that's not true of all of them so you'll need to pay attention to the specs on whatever board you're looking at you can do your development on the Arduino IDE I have successfully compiled code with the latest one you can also use expressf IDE there's also Lua rtos and you can use micro python with this as well but then there's also the lvgl graphics library that you can use to do your graphical displays one thing I will tell you there's a and we'll look at that but there's a product from Square line that is free to use for as long as you want they have a they have a trial that you can get which is full featured and then when this trial expires you'll need to create a login and then you can continue using it as the Community Edition that's pretty typical with a lot of these uh these types of software that you can there's a a developer license that goes now the community license is for non-commercial use it's for development it allows you to learn the board learn how to use it but you can't use any of the code for in there for to resell the developer package has a commercial rights in it as well and it offers additional capabilities there's also an Enterprise version so if you have multiple people that are doing development you can buy your licenses as for Zoom at a discount what can you use this for well with some of the use cases well obviously you this this would fit in a thermostat type of a situation in a home it's or a business this would also work Automotive as an automotive display maybe you're wanting to bring out some critical functions of the engine that you can then see on your dash medical equipment it could be used there there's also industrial control there's power applications for this managing power and also civil Electronics there's home automation you can also use it as a GPS energy and also of course internet of things can be done with this as well I'm gonna I'm Gonna Leave a link to the spec sheet because it if I put it up here it'll look like an eye chart and we won't be able to see it but I will highlight a few things so both the model five the five inch and the seven inch have PS RAM and they have eight megabytes worth of it so why why would you want that psram allows you to load those programs into memory and then you can recall them from there so it's a lot faster obviously than trying to run from the from the TF cart the next step down the four and a half also has PS Ram but only two megabytes worth the rest of the ones all the way down to 2.5 inches they don't have PS Ram at all so yeah you might that might be a consideration if that that's of interest to you in your application the prices for this run on the from the 2.4 for about 13.93 at the time I'm doing this video up to the version 7 which is thirty dollars and three cents and then this one is about 27.93 the five inch is about 27.93 now you'll want to look at their website to confirm those prices so where am I with this so I'm not going to do I'm not gonna attempt to do a demo so I am in the process of learning this I've had this for a month I've been able to work with it for about a week maybe two almost two now so if you go to the where it says shop and pick a product if you scroll down you'll start to see uh listings for examples and documents and yeah they have a full set of schematics for every one of the boards they have there's documentation that they have for this board for the lvgl and of course lbgl also has their own documentation that you can read through as well which is where I'm at right now is perusing through all of that so there's a lot of things to I mean for me the I'm kind of in that fog of the learning curve where I'm I'm not sure what to learn next but I'm just following the progression that was laid out for me by one of the manuals so and just going through some of the getting started examples starting to become familiar with the Arduino IDE now originally their advice was to use the version one and and uh and and that works yeah that will work but I wanted to try the lbgl and up and you need to use the ver the the latest version of the Arduino IDE for that at least that's what I have found it's just my unfamiliarity with the Arduino code base so yeah this is one of the things that was on my bucket list to learn and I want to thank Electro for sending me this and letting me have an opportunity to fill one of my bucket list items I have I have some things I want to do with this I'd like to be able to transmit data to this over the over Wi-Fi and and have it show status of my servers on the on the back back there and so I can see kind of what's going on with it and and yeah that's what I would like to use it for so uh I'll be back because I'm gonna come back and when I master the development process I will show you what I have accomplished with it so but I I don't feel like I'm ready to do that yet you know unless unless the demo you want to see is just turning the screen on because that's as far as I've gotten with the lvgl stuff so far so yeah I'm working through it working through it that's that's the like step one that's like the baby step step one into lvgl so I've progressed through all of the all the examples leading up to lvgl now I've gotten to the one where all right let's see if the screen will come on and then we'll start adding stuff to it so I hope you enjoyed this video today and if you did please like And subscribe and thank you to my patreons thank you for your support thank you also to my channel members I sure appreciate you and thank you for watching the video hope to see you in the next one bye for now [Music] [Music] foreign [Music] foreign [Music]
