M5Stack M5Stamp C3 Mate with Pin Headers

M5Stack M5Stamp C3 Mate with Pin Headers features an Espressif ESP32-C3 RISC-V MCU with Wi-Fi and BLUETOOTH® 5 (LE) connectivity for IoT edge devices, designed for home appliances and industrial automation. The M5Stamp C3 Mate offers a more secure way to answer the Bluetooth security concerns by merging the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption. This also makes the M5Stamp C3 optimal for industrial IoT equipment collecting sensor data within a factory or a building.

The M5Stack M5Stamp C3 Mate with Pin Headers operates at a maximum clock frequency of 160MHz, with 400KB of internal RAM and 4MB Flash, facilitating many different uses involving connected devices.

Additionally, the Stamp-C3 delivers full Bluetooth 5.0 long-range (LR) support, including long-range and mesh networking functions, and manages building devices with great coverage and improved usability. Moreover, the exceptional heat resistance plastic enclosure is sustained at a higher operating temperature.


  • Three types of soldering options (SMT, DIP, flywire)
  • High-temperature resistant plastic enclosure with peak temperature at 230°C
  • Integrates a 5V->3.3V DC/DC design, GPIOx13, programmable RGB LED x1, Reset button x1, button x1, and 3D antenna
  • Compatible with Arduino, ESP32-IDF, and other mainstream development platforms (UIFlow support coming soon)
