m5Stack C050-B M5STAMP-PICO features an ultra-compact design with two low-power Xtensa® 32-bit LX6 microprocessors at 240MHz on a PCB that is tiny and is as delicate as a postage stamp. It is ideal for space-constrained or battery-powered devices such as wearables, medical devices, sensors, and other IoT devices. The device has five options of installation (SMT, DIP, flywire, grove interface), which provides endless possibilities. The device comes with a high-temperature resistant plastic shell, 3D antenna, and components to provide excellent protection.

The M5Stack M5STAMP-PICO supports UIFlow graphical programming platform, scripting-free, cloud push, and is fully compatible with Arduino, MicroPython, ESP32-IDF, and other mainstream development platforms. This feature allows the user to build various applications quickly. The M5STAMP-PICO contains a 5V to 3.3V DC/DC port, GPIOx12, programmable RGB light x1, button x1, finely tuned RF circuit, providing stable and reliable wireless communication. The device also offers easy access to M5Stack's hardware and software ecology system with many sensors, actuators, functional modules, and accessories to choose from. All provide for speedy adaptation.
