In this project, we'll create a smart access control system using ESP32, RFID units, and M5StickV. The system supports RFID card reading, QR code recognition, and “offline-cloud platform” interaction via MQTT. Key features include RFID read/write capabilities, MQTT-based data communication, and user interface interaction via M5GO Lite.   Project Objectives Card Punching System: Implement...

M5Stack AtomS3U is a multifunctional development board that can be used for IoT human-computer interaction, voice input/recognition (STT), IO control and other scenarios. It adopts Loxin ESP32S3 main controller chip, dual-core Xtensa LX7 processor with 240MHz main frequency and comes with WiFi function. The shape design is similar to a USB flash drive, compact...

M5Core2 is the second generation of M5Stack development kit series host, in the original generation of host based on the further enhancement of the function, hardware features more complete. Its core host Core2 is equipped with ESP32-D0WDQ6-V3, with two separately controllable Xtensa® 32-bit LX6 processor, the main frequency of up to 240Mhz, support for...

As we enter the era of intelligence, cloud-based intelligent communication devices have become very popular in our lives. This article will use M5Stack's UiFlow development interface (Blocky) to complete the access control system with cloud-based record function, including four kinds of authentication locks (mobile phone remote unlocking, RFID card, keystroke passwords, fingerprint identification), and...

The M5StickC PLUS is a miniature development board based on the ESP32-PICO-D4 chip with a compact and powerful design. It integrates a wide range of sensors and modules and is ideal for rapid prototyping and developing Internet of Things (IoT) applications.   M5StickC PLUS is the large screen version of M5StickC, the main control...
