M5Stack Tab5

1. Outline

The M5Stack Tab5 is a versatile portable device ideal for education, research, commercial, and advanced DIY projects. It features an ESP32-P4 main controller with 16MB Flash and 32MB PSRAM, offering Wi-Fi and Bluetooth 5.2 connectivity via an ESP32-C6-MINI-1U module.

The device boasts a 5-inch IPS touch screen (1280x720 resolution) with an IL9881 driver for a vivid visual experience and smooth touch response. It includes an SC2356 camera capable of high-resolution video recording and image processing, including facial recognition and object tracking.

Connectivity options include USB-A and USB Type-C ports (with OTG support), a GROVE interface, and an M5BUS modular interface for expansion. It also supports a standard keyboard and has a Micro SD card slot for additional data storage.

For communication, the Tab5 features an RS485 port with a SIT3088 chip and a 1202 termination resistor for stable data transmission. A reserved STMAP pad interface allows for expansion with modules like Cat.M, NB-IoT, or LoRaWAN.

Audio capabilities are provided by an ES8388 chip, a 1W NS4150B speaker, a 3.5mm headphone jack, and an efficient dual-microphone system for enhanced audio recording and voice recognition.

The device is powered by a 2S battery via a bottom battery interface, ensuring continuous operation. A BMI270 6-axis motion sensor is integrated for dynamic monitoring, providing precise acceleration and gyroscope data.

An easily accessible user button simplifies device operation, including power control and quick entry into programming mode.

These features make the Tab5 suitable for smart home applications, remote monitoring, IoT device development, and professional projects requiring portability and high performance.

3. Quick Start

Refer to the Espressif Flash Download Tools documentation for detailed setup: Espressif Flash Download Tools.

3.1. Scan Wi-Fi

1. Open the Flash Download Tools executable (e.g., ESP32 Flash Download Tool).
2. Select the ESP32-P4 chip type.
3. Settings:
   • Select the firmware file: tab5_wifi_scan_firmware_v0.1.bin.
   • Set the starting flash address to 0x0.
   • Enable the firmware for upload.
   • Configure the upload speed and mode (e.g., 40MHz, QIO).
   • Select the correct COM port and baud rate (e.g., COM5, 115200).
   • Click "START" to begin flashing.
4. After flashing, reset the device by pressing the reset button or reconnecting it.
5. Open a serial port tool (e.g., Serial Debug Assistant) and select the corresponding COM port.
6. The Wi-Fi scan results will be displayed in the serial monitor, showing SSIDs, RSSI, and authentication modes of detected Wi-Fi networks.
