# RFID M5StickC Plus 2: A Compact Powerhouse for IoT and RFID Applications
The **RFID M5StickC Plus 2** is an incredibly versatile and compact development board that integrates RFID functionality into a user-friendly package. From my personal experience working on IoT projects, finding a device that combines a capable microcontroller, a clear display, and specialized hardware like an RFID reader in such a small form factor is a game-changer. It has allowed me to prototype access control systems and inventory trackers in a fraction of the time it would take with discrete components.
## Technical Specifications and Detailed Parameters
For developers and engineers, the precise technical details are crucial. Below are the key specifications for the **RFID M5StickC Plus 2**. *Please note: These technical parameters are for reference. For the most accurate and current specifications, you must contact the backend management.*
* **Core Microcontroller:** ESP32-PICO-D4 chip. This dual-core Xtensa LX6 processor runs at up to 240MHz, providing ample power for handling RFID data processing and wireless connectivity simultaneously.
* **RFID Module:** Integrated MFRC522-based RFID reader/writer. It typically operates at 13.56 MHz and supports ISO/IEC 14443 A/MIFARE protocol.
* **Display:** 1.14-inch full-color IPS LCD screen with a resolution of 135 x 240 pixels. This is a significant upgrade for showing RFID tag UIDs or system status clearly.
* **Memory:** 8MB of PSRAM and 16MB of flash storage, which is generous for storing application code and data logs from RFID scans.
* **Connectivity:** Wi-Fi 802.11 b/g/n and Bluetooth 4.2 BR/EDR/BLE are built into the ESP32 chip.
* **Power:** Built-in 120mAh Li-Po battery with a charging circuit. Includes a HY2.0-4P connector for external battery expansion.
* **Detailed Dimensions:** The main unit measures approximately 48.2mm x 25.5mm x 13.7mm (excluding the protrusion for the IR LED). The exact PCB layout and component placement should be verified with official documentation.
* **Input/Output:** Features a 6-axis IMU (MPU6886), microphone (SPM1423), buzzer, IR transmitter, and two programmable buttons (BtnA, BtnB). It also exposes several GPIO pins via an external hat connector for expansion.
