M5Stack just added a new family to its popular series of modules with the Stamp-C3!
The new Stamp-C3 features an Espressif ESP32-C3 RISC-V MCU with Wi-Fi and Bluetooth 5 (LE) connectivity for IoT edge devices such as home appliances and Industrial Automation.
By combining RSA-3072-based secure boot and the AES-128-XTS-based flash encryption, M5Stack offers a more secure way to answer Bluetooth security concerns whilst also making it optimal for industrial IoT equipment, collecting sensor data within a factory or a building.
The Stamp-C3 is based on a 32-bit RISC-V microcontroller and operates at a maximum clock frequency of 160 MHz. With 400 KB of internal RAM and 4 MB Flash, it can facilitate many different use-cases involving connected devices. The Stamp-C3 provides full Bluetooth® 5.0 long-range (LR) support including long-range and mesh networking functions and achieves building devices with great coverage and improved usability. Furthermore, the exceptional heat resistance plastic enclosure is sustained at a higher operating temperature.
Features
Multiple Styles
Three types of soldering options are available (SMT, DIP, flywire) with a high-temperature resistant plastic enclosure. Peak temperature = 230℃
High Integration
The Stamp-C3 features 5V->3.3V DC/DC design, GPIOx13, programmable RGB LED x1, Reset button x1, button x1 and a 3D antenna providing stable and reliable wireless communication.
Low Code Development
The Stamp-C3 is fully compatible with Arduino, ESP32-IDF and other mainstream development platforms to quickly build various applications (UIFlow support coming soon).
