M5Stack Tab5 IoT Development Kit (ESP32-P4)

Product Link

M5Stack Tab5 IoT Development Kit (ESP32-P4)OpenELAB Technology Ltd.

Description

Tab5 is a highly extensible, portable smart IoT terminal development device designed for developers, integrating a dual-chip architecture and abundant hardware resources. Its main controller adopts the RISC‑V–based ESP32‑P4 SoC, equipped with 16 MB Flash and 32 MB PSRAM; the wireless module uses the ESP32‑C6‑MINI‑1U, supporting Wi‑Fi 6. Its antenna system can freely switch between the built-in 3D antenna and the external MMCX antenna interface, flexibly adapting to different deployment environments to ensure data throughput and low-latency control.

In terms of vision and interaction, Tab5 features a 5″ 1280×720 IPS TFT display via a MIPI‑DSI interface, with touch handled by the GT911 multi-point touch controller (I²C) for a smooth and responsive touch experience; it also includes an SC2356 2 MP camera (1600×1200) via a MIPI‑CSI interface, capable of high-definition video recording, image processing, and edge AI applications (e.g., face recognition, object tracking).

For peripheral interfaces, Tab5 offers USB‑A (Host) and USB‑C (USB 2.0 OTG) ports for connecting traditional peripherals like a mouse or keyboard; industrial scenarios can use RS‑485 (SIT3088 + DIP switch–selectable 120 Ω termination) bus communication. Grove, M5BUS, GPIO_EXT header, and Micro SD card slot, as well as reserved STAMP pads (supporting Cat.M, NB‑IoT, LoRaWAN, etc.), allow flexible expansion with various sensors and communication modules. It also includes Reset/Boot buttons for quick reset and entering firmware download mode.

In audio/video, Tab5 uses the ES8388 audio codec, paired with the ES7210 AEC echo-cancellation front end, a dual-microphone array, a 3.5 mm headphone jack, and a speaker for high-fidelity recording/playback and accurate voice recognition. The built-in BMI270 6-axis sensor (accelerometer + gyroscope, with interrupt wakeup) can trigger the main controller in motion-tracking and posture-detection scenarios, improving responsiveness in low-power conditions.

For time and power management, Tab5 integrates the RX8130CE real-time clock (with timed interrupt wakeup), supports a removable NP‑F550 lithium battery, and includes MP4560 boost/buck management, IP2326 charge/discharge control, and INA226 real-time monitoring circuitry—ensuring stable operation without external power.

Structurally, Tab5 features a standard 1/4″‑20 tripod mount on the side, allowing direct attachment to tripods or other mounts for easy shooting and deployment.

Tab5 is suitable for smart home control, remote monitoring, industrial automation, IoT prototyping, education, and research—providing developers and enterprises a comprehensive, easily expandable, high-performance development platform.
