 Introducing ELPMS3LW, the ESP32S3 and Laura are meeting one compact and power efficient module. First of all, thank you for your support in the last video. This module was designed together with ELPMS3, so there will not be changes that many of you have requested. In this video, I want to share with you all progress we have achieved in the last few weeks during the development of ELPMS3LW. So the idea behind this project is very simple, combine these two modules into one solution. As you can see, this is the first version of the ELPMS3LW, and the main features of this module are multi-protocol and powerful module based on ESP32S3 and SX1276, compact size module, full compatibility with Laura and Laura1, power latch circuit with RTC-like ELPMS3, integrated LDO, battery level circuit and RHB status led under the X. So basically we have the opportunity to use three different communication protocols with the ELPMS3LW, Wi-Fi, BLE and Laura. So just imagine how many products and projects you can develop with this module. It's perfect for developing nodes based on Laura and Laura1, also small gateways can be designed with this module. In general, the ELPMS3LW is ideal for industrial applications, and now let's look at the module in detail. But first, this video is sponsored by PCBWay. You can buy your PCBs for only $5, check the link below to place your first order. As you can see, the PCBs provided by PCBWay are great, soldering these modules by end is not very easy because the components are very small. And also PCBWay manufactures these aluminum shields. Taking into consideration that I will be using a pick and place machine in production, I am setting up a production line to manufacture this project and others. I'm satisfied with the final result and you what do you think? To simplify the use of the ELPMS, we have developed a devkit called the Objects Link. This is the first prototype we developed two months ago, so let's break down the devkit together. Originally, the idea was to develop a compact solution, which is why we used Zlimstar connectors, but we feel they are not very user friendly. That is why we will use only other connectors in the final version. How often do you find yourself developing a project and is you have to connect an external power supply or use the CDC step up to get a voltage either than 5V? With Objects Link, you no longer have to do that because it supports power delivery 3.0 PPS. You will be able to get up to 20V 5A, so 100W. Trust me, that is a lot for the most of IoT projects. And it's also PPS, which means you will be able to get a specific voltage or current value. This is a small demo. With this button I increase the voltage by 0.5V each time I push it. You understand that I could use this feature to control the brightness of the led strip and several projects can be made using power delivery. Another key feature of this devkit is that the CDC that supports up to 58V can be very useful in industrial applications. And we also add a new expander to handle for example relays or other peripherals, again for industrial use. And last but not least, we try to add in a crypto chip, honestly we don't know if it's a useful feature considering that the ESP32 S3 already provides similar features. And what do you think about that? So guys, this is our first prototype of Objects Link and we have already designed a new version and I will show it in the next video. During the testing of the ELPM S3 LW I used the Zimaboard 842 to do some tests. You can use Zimaboard for different purposes such as smart home applications to connect all your devices. You can also install RedNode and other call-ups for IoT. And there are many expansion ports such as PCI, SATA, Ethernet and USB and I suggest you to see the links below in the description about Zimaboard. And I thank you Zimaboard for sending me this unit and I will design several projects with this awesome product. I performed several tests, in particular I will show you the tests concerning Lora and Lora1, just for your reference in all tests I used two antenna models of 868M with 3 and 5 dB. The first test I did was Lora point-to-point. This test consists of connecting two ELPM S3 LW with Lora, one module send data and the second one receive it. As you can see, it's worked correctly. The next test was Lora1 with power latch. In this first test with Lora1 I also used power latch. Basically the ELPM S3 LW module start up every time the power latch is triggered and it send data to my Lora1 gateway. Another test was Lora1 with power latch and RTC. This test is similar to the previous one, only that the power latch is triggered every minute by the external RTC. Remind you that until the power latch is triggered the whole module is off. The last test I want to show you is long range test with Lora1. In this test I also want to compare the ELPM S3 LW with this module I bought. Before doing the outdoor test I did a first test in house with some obstacles and with a maximum distance between the two nodes and the gateway of 12 meters. To perform the outdoor test I placed the gateway near the window of my house. Then I drove away with the two nodes in my car and I did the test in the city where there are several obstacles yet the node lost connection with the gateway after 1.2 kilometers. The signal strength of the ELPM S3 LW is better compared to the other module. From my point of view this is a very good result and by doing other tests I can ensure you that the module can work at maximum distance from the gateway between 5 and 10 kilometers without any obstacles. This is the new version of the ELPM S3 LW. As you can see it's so different compared with the first version. I made some changes and also followed many of your suggestions. First I added the castlated holes and reducing the size of the module. Now it's easier to solder the pads and it's easy to use the module in your design. The shield is no longer made of aluminum but tin plate the stainless steel. I changed the SX1276 to SX1262 and also now you can set the frequency band between 868 and 915 MHz. I added a ceramic antenna for Wi-Fi and BLE so for the ESP32 S3. There are two 50 ohm pads to install external antennas and there is also a second LDO to power only the lower side of the module. So I have improved the wall power unit it's now possible to individually power the following components so the ESP32 S3, the SX1262, the RTC and RGB LED. And now the wall power block that includes power latch and RTC will be called a deep stop. In the bottom side there is also a useful C screen and now we have a standard footprint for the ELPMS3 and ELPMS3 LW. The difference between the two modules will merely be the inclusion or absence of the lower portion. And the design is now optimized for mass production. If you have any suggestions to add more features please write them below. In the description you can find the link to download the documentation of the ELPMS3 LW. The ELPMS family is growing and I am already working on other versions of the module. In the last few weeks I have been working hard to improve the project and everything is almost ready for the sale of the ELPMS3 and ELPMS3 LW. For now I will sell engineering samples of the modules and also the depth kit. In this way you will also be able to try them out easily. I am also working about the certification of the modules and so guys what do you think about this new module? I look forward to your feedbacks below. And thank you guys for watching this video until the end and see you next time!
