How does a shopping list work?

Once logged in, you can place and store any number of products on your shopping list indefinitely.
Adding a product to your shopping list does not automatically mean you have reserved it.
For non-logged-in customers the shopping list is stored until the session expires (about 24h).

Platform / CPU: Choose the Heart of Your Gateway

( number of products: 5 )

ESP32 for flexibility and wireless connectivity, or STM32 for uncompromised industrial reliability? We help you make the right choice.

Choosing a microcontroller is the most important decision when designing a programmable IIoT system. It's not just a technical specification—it's a choice of an entire programming ecosystem, capabilities, and operational philosophy.

In this section, we'll help you understand the key differences between our gateways based on the flexible ESP32 platform and those that use the ultra-efficient and reliable STM32 core.

The Heart of Your Gateway: What Defines the Platform?

Each of our programmable gateways is designed to give you maximum freedom in creating custom solutions. However, the choice of CPU platform determines what tools you'll have at your disposal and what applications the gateway is best suited for.

Programmable IIoT Gateways with ESP32

The ESP32 platform is the Swiss Army knife of the IoT world, perfect for rapid prototyping and projects where wireless connectivity and programming flexibility are key.

Key Strengths: Built-in Wi-Fi, a massive community, and support for the Arduino IDE and MicroPython.
Best for: Applications where fast deployment, wireless communication, and leveraging thousands of ready-made libraries are important.

Quick Guide: Which Platform to Choose?

Choose ESP32 if:	Choose STM32 if:
Wireless Wi-Fi connectivity is a priority.	Maximum stability and reliability of a wired connection is the priority.
You want to get started quickly using the Arduino IDE or the simplicity of MicroPython.	You need deterministic, real-time operation and plan to use FreeRTOS.
Your project requires flexibility, and you value the support of a massive open-source community.	You are building a mission-critical system where performance and predictability are more important than programming flexibility.
