When it comes to hardware development, many challenges appear. Technical, commercial, logistical, financial issues, etc.
Something that impacts all these factors is the existence of multiple providers. With each of them it will be necessary to negotiate prices, delivery times, confidentiality agreements, etc.
On the purely technical side, there are design, integration, certification and other challenges.
In this situation a question arises.
Is it possible to solve all these problems at once?
The solution is in the modular design
Take the case of products that require certifications, such as wireless devices.
Paying for a certification of a wireless product is a very high barrier for small businesses. The costs are very high and are not justified by the production of small quantities.
The use of modules comes to solve this problem. The large manufacturers carry out the certification of these modules and prorate it on huge quantities of products. In this way, startups can develop their products without having to pay high certification costs.
At the same time, the problem of getting all the components, assembling the PCB, sending it to production, etc. is solved. We simply add the module to our product, which in many cases may be the most important hardware to include.
There is no doubt that the modules have opened the doors to a production more focused on developers and small businesses. And in this way they have also generated products extremely adapted to specific uses and customer requirements.
Develop an IoT device as a block game
In 2020 I had the opportunity to attend The Thing Conference in Amsterdam. There I was able to see the presentation of RAK Wireless, where Kinson Chan presented the WisBlock solution.
Through very ingenious design, the company had managed to develop a system that allows the combination of different pieces of hardware as if it were a set of blocks.
In this way, processors, communication interfaces and sensors of all kinds can be combined, simply by fitting these blocks together.
In this way it is possible to have a working prototype in a matter of minutes. It is even possible to build the final products using this system.
Without a doubt, developing an IoT device in this way is very easy.
There is a wide variety of WisBlock modules and if the sensor you are looking for is not there, you can use any interface (I2C, UART, ADC, GPIO, RS485, etc) to connect what you need.
On the communications side you can find LoRa/LoRaWAN, Cellular LTE-M/NB-IoT, Wi-Fi and Bluetooth. At this point it is good to clarify that RAK Wireless places a special emphasis on LoRa/LoRaWAN, since it also offers ready-to-use gateways and products.
Here I leave you a link to RAK Wireless store so you can take a look at these products. I clarify that this link is an affiliate link, so if you make a purchase I will receive a small commission for the sale. However, this will not result in an additional cost to you and at the same time you will be contributing to support this blog, where I publish free and valuable information about IoT.

Developing an IoT device is a complicated issue, but through the use of modular solutions it is possible to limit the costs and the delivery time to the market.
