Switch Science, M5Stack's ultra-compact design "M5Stamp" series new product "M5Stamp C3U" will be on sale from January 14, 2022 Company Release | Nikkan Kogyo Shimbun Electronic version

Release issuing company: Switch Science Co., Ltd.

Switch Science Co., Ltd. (hereinafter referred to as Switch Science, Headquarters: Shinjuku-ku, Tokyo, CEO: Shigeru Kanamoto) has released the new product "M5Stamp C3U" from M5Stack (Headquarters: Shenzhen, China) to the Switch Science web shop. Sales will start on January 14, 2022. "M5Stamp C3U" is a postage stamp-sized module equipped with Espressif ESP32-C3 RISC-V MCU for IoT edge devices with Wi-Fi and Bluetooth(R) 5.0 long-range (LR) functions. The difference from "M5Stamp C3", which went on sale on October 21, 2021, is that the USB conversion IC has been omitted. In "M5Stamp C3U", the USB type C port is directly connected to the ESP32-C3, and the program is written with the USB serial function built into the ESP32-C3. This time, we will start selling two types of "M5Stamp C3U (5pcs)" with 5 pieces and "M5Stamp C3U Mate" which is a set of pin headers. "M5Stamp C3U" can use Wi-Fi and Bluetooth (R) 5.0 long-range (LR) functions. By combining RSA-3072-based secure boot and AES-128-XTS-based flash encryption, it is safer than the conventional M5Stack in industrial IoT equipment such as collecting sensor data in factories and buildings. Provides Bluetooth security. Based on a 32-bit RISC-V microcontroller, it operates at a maximum frequency of 160 MHz, has 400 KB of internal RAM and 4 MB of flash, and can be used in a variety of use cases. In addition, full-featured Bluetooth(R) 5.0 long-range (LR), including long-range and mesh networking capabilities, enable building devices with wide coverage and high usability for buildings. In addition, the enclosure with superior heat-resistant plastic supports high operating temperatures. ▶︎ Difference from M5Stamp C3 In "M5Stamp C3U", the USB conversion IC was omitted, and the USB type C port was directly connected to the ESP32-C3.
