Jan. 23, 2026 – M5Stack, a global leader in modular IoT and embedded development platforms, today announced the launch of StickS3, the latest addition to its signature Stick series.
Built for developers and makers, StickS3 is a compact, high-performance programmable controller designed for remote control and IoT applications. Powered by the ESP32-S3-PICO-1-N8R8, it delivers enhanced performance and optimized interaction capabilities, making it well suited for smart devices and a wide range of IoT development scenarios.
To enable these capabilities, StickS3 introduces a series of meaningful hardware and capability upgrades:
Key Features
Upgraded Core
Powered by ESP32-S3-PICO-1-N8R8, StickS3 ensures higher processing performance, USB-OTG support, Bluetooth LE 5, and improved suitability for AI and edge computing applications, compared with the ESP32-PICO-V3-02 used in StickC-Plus2.
Enhanced Audio
StickS3 upgrades its audio system with an ES8311 mono audio codec, a MEMS microphone, and an onboard speaker, enabling true audio input and output for voice interaction and audio playback.
Extended Battery Life
StickS3 is equipped with a 250 mAh internal battery, providing stable power support for extended interactive use cases.
Expanded Memory
StickS3 comes with 8 MB Flash and 8 MB PSRAM, providing significantly expanded program storage and runtime memory.
Enhanced Expansion Options
StickS3 features the newly added Hat2-Bus (2.54-16P), giving access to more GPIO and communication resources, along with an integrated IR receiver for infrared control.
Detailed Specification
Development Potential
Beyond the hardware upgrades, the real strength of the Stick series lies in its development ecosystem and community creativity. With its compact form factor and ease of use, the Stick Series has become a signature product line within the M5Stack family, offering rich development potential and a wide range of use cases—especially for beginners.
Taking StickC-Plus2 as an example, the community has built a diverse collection of projects and custom firmware around it. Thanks to its portable design, it has been widely adopted for wearable and handheld applications, enabling creators to turn it into anything from a smartwatch to a security-testing tool.
Now, with the release of StickS3, a more powerful and highly integrated evolution of the series, it’s time to unlock even greater possibilities—driven by both the enhanced hardware and the passionate community behind Stick.
