According to CNX Software and It's FOSS in April 2026, Espressif's ESP32-S31 brings several kinds of connectivity into a single chip, aimed at industrial hubs and gateways.
Summary in 3 lines
According to CNX Software and It's FOSS in April 2026, Espressif has a new chip called the ESP32-S31. Reportedly, it has a dual-core RISC-V CPU at 320 MHz and combines Wi-Fi 6, Gigabit Ethernet, Bluetooth 5.4 and IEEE 802.15.4 in one chip. The details come from secondary sources, so check the real specifications on Espressif's website before relying on them.
What is the ESP32-S31?
The ESP32-S31 is a chip from Espressif that technology media reported on in April 2026. According to those reports, its key feature is putting several communication options into one chip, instead of combining several separate chips. This article relies on media reports rather than documents from the manufacturer itself. Details may differ from the final specifications or change later.
Main specifications, as reported
According to the reports, the chip uses a dual-core RISC-V design running at 320 MHz. For connectivity, it includes Wi-Fi 6, Gigabit Ethernet, Bluetooth 5.4 and IEEE 802.15.4 in the same chip. Having fast wired networking and several radios in one device makes this kind of chip interesting for products that sit between different networks.
Why it suits gateways
According to the reports, the chip is suited to industrial hubs and gateways. A gateway collects data from many kinds of end devices and forwards it to a network or the cloud, so having Ethernet, Wi-Fi and short-range radios in one chip fits that role conceptually. Still, choosing a chip for a real product involves other factors, such as availability, documentation, development tools and the requirements of each application. Those are beyond the information in this article.
A note on sources
Because everything here comes from secondary sources, anyone planning a design or a purchase should check the real specifications on Espressif's website first. The figures and features in this article are what was reported, not a statement from the manufacturer.
How this relates to TMRX
Chips like this suit gateway work, and the idea can build on TMRX's concept of a DIN-rail Wi-Fi gateway: a device in the middle that brings field data into a system. TMRX does not have a product that uses the ESP32-S31. This article simply shares a trend in gateway chips for readers who want to follow it.
