Espressif has released the ESP-Mosaico, a modular development kit built around the ESP32-S31 microcontroller. Third-party vendors have begun listing the hardware for approximately $117 on AliExpress.
Why it matters
The board integrates advanced wireless standards and graphical interface capabilities into a compact, modular package. Its release provides developers with a versatile platform for testing IoT applications that require high-resolution touch input.
The device features a 2.16-inch AMOLED touch display with a 480 × 480 resolution, driven by an ESP32-S31 microcontroller operating at up to 320MHz. It includes 16MB of PSRAM and 16MB of SPI NOR flash, alongside a 128MB SPI NAND device for additional storage.
The players
Espressif
A designer and manufacturer of low-power Wi-Fi and Bluetooth system-on-chip solutions used extensively in consumer IoT.
AliExpress
A global online retail platform currently serving as the initial point of sale for the new development kit.
The details
The ESP-Mosaico uses a two-part architecture consisting of a CoreBoard and a BaseBoard linked by a 60-pin board-to-board connector. The display utilizes a CO5300 controller connected via QSPI (a high-speed interface for flash memory), while motion sensing is handled by a Bosch BMI270 inertial measurement unit and two BMM150 magnetometers. Connectivity is provided by a radioset supporting Wi-Fi 6, Bluetooth 5.4, and IEEE 802.15.4 communication protocols.
Timeline
September 27, 2026: The ESP-Mosaico was reported as released with third-party availability.
The Tech Race
The ESP-Mosaico represents the latest iteration in Espressif’s roadmap to integrate high-end display controllers into the ESP32 series. It competes with other modular development boards by packing specialized sensors and Wi-Fi 6 capabilities into a single, cohesive form factor.
The kit is currently available through third-party retailers for hobbyists and developers looking to prototype compact, screen-based IoT projects. Users should note that the device requires familiarity with embedded firmware development to leverage the onboard AMOLED display and sensor suite.
The takeaway
This development kit highlights the industry trend of integrating higher-performance displays and wireless connectivity into small-scale microcontroller boards. Developers should monitor official Espressif announcements for potential documentation updates and broader distribution windows.
