M5Stamp C3U Mate with Pin Headers

PRODUCT DETAILSDescription The newly M5Stamp C3U featuring ESPRESSIF ESP32-C3 RISC-V MCU, with Wi-Fi 5 (LE) connectivity, applicable for home appliances and Industrial Automation. By combining RSA-3072-based secure boot and the AES-128-XTS-based flash encryption. The compact size and powerful functions, make it applicable for multiple IoT scenarios.The M5Stamp C3U is based on 32-bit RISC-V micro controller, 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 M5Stamp C3U provides, Furthermore, the exceptional heat resistance plastic enclosure is sustained at a higher operating temperature.Note: If you need to use SPIFFS filesystem in Arduino IDE. Please install a patch package first.Product Features MULTIPLE STYLE: Three types soldering options are available (SMT, DIP, fly wire); High-temperature resistant plastic enclosure, Peak temperature = 230℃; HIGH INTEGRATION: M5Stamp C3 contains 5V->3.3V DC/DC design, GPIOx14; USB Type C port; Programmable RGB LED x1, Reset button x1, button x1; 3D antenna, providing stable and reliable wireless communication. DEVELOPMENT PLATFORM: Arduino, ESP32-IDF (UIFlow support coming soon) Application DIY, Prototyping Industrial Automation Smart Home Wearable Devices Medical Devices Consumer Electronics Note: The newly updated C3U shares the same features as C3, but the difference is that M5Stamp C3U without the USB download chip and the program download method is different（(The C3U uses the ESP32-C3's built-in USB Serial for program download)）. If you are looking for a more affordable project, you can add this to your shopping list!Program Download/Notes Enter the program download mode operation:1. Long press the center button (G9) of STAMP C3U under power failure condition.2. Connect to the computer, after the port is successfully identified, program burning. USB CDC enabled:By default, USB CDC is not enabled, the serial port output started by C3U will be output through UART0, if you need to output through USB, please use IDE to make it USB CDC before downloading the program option enabled. (Arduino users can enable it through Tools->USB CDC on Boot-Enabled, IDF users please refer to ESP IDF official documentation.)product comparison Model Master IO quantity Button IO USB chip USB interface function STAMP-C3 ESP32-C3 13 G3 CH9102 Download / Serial STAMP-C3U ESP32-C3 14 G9 / Download / JTAG / CDC Serial Specifications Specifications Parameters ESP32-C3 32bit RISC-V single-core processor, clocked at 160 MHz Storage 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB FLASH Wi-Fi 2.4 GHz band supports 20 MHz and 40 MHz bandwidth, IEEE 802.11 b/g/n protocol, data rate up to 150 Mbps Input voltage 5V @ 500mA HMI Programmable physical button x 1, reset debugging button x 1, programmable RGB LED (SK6812) x 1 USB interface TypeC x1 Antenna Type 2.4G 3D Antenna Module peripheral interface resources ADC, GPIO, SPI, UART, I2C, I2S, PWM, RMT, DMA, USB serial port, TWAI IO interface x14 G0, G1, G3, G4, G5, G6, G7, G8, G9, G10, G18, G19, G21, G22 IO interface spacing 2.54mm Fixing screw specifications M2*4 countersunk head hexagon socket mechanical teeth Net weight 3.8g Product size 34 * 20 * 4.6mm Packing size 85*55mm sealing bag (translucent) LEARN AND DOCUMENTSDOCUMENTS
