Integrates dual-core processor for robust performance
Supports versatile power supply modes, including DC and battery
Features USB Type-C and Type-A for seamless connectivity
Facilitates precise power management via STM32 coprocessor
Enables human-machine interaction with indicator lights and buttons
The M5Stack PowerHub is a sophisticated programmable controller designed for multi-channel power management. It incorporates the ESP32-S3-WROOM-1U-N16R8 main control module, which features a dual-core Xtensa LX7 processor capable of operating at speeds up to 240MHz. This module supports 2.4 GHz Wi-Fi connectivity and is equipped with 16MB of Flash memory and 8MB of PSRAM. The device also includes a built-in STM32G031G8U6 coprocessor and multiple INA226 voltage/current detection ICs, which together facilitate precise power state management across various expansion interfaces. This enables accurate control of power consumption and provides low-power wake-up functionality for the entire device.
The PowerHub is equipped with a USB Type-C port for program downloads and USB OTG functions. It features an internal USB interface switch that allows the bottom USB port to be redirected to either the front USB Type-A or USB Type-C interface, thereby enhancing the expansion capabilities for USB peripherals. The device supports multiple power supply modes, including DC power, 2S battery power, and PWR485/PWR CAN input power. It is also equipped with 2x HY2.0-4P Grove ports, RS485, and CAN communication interfaces, making it suitable for connections to various sensors and industrial control devices.
Ideal for applications in industrial automation control and smart home environments, the M5Stack PowerHub offers developers a stable and reliable IoT solution. It is designed to facilitate human-machine interaction through multi-channel status indicator lights and physical buttons, and it supports multiple mounting methods for versatile installation options.
RS485 communication interface with built-in 120Ω terminal resistor switch
CAN bus communication interface with built-in 120Ω terminal resistor switch
2.4 GHz SMA mini antenna
Multiple power supply modes: PWR485/PWR CAN input power, 2S battery power supply, DC 7-20V power supply
Human-machine interaction with multi-channel status indicator lights and three physical buttons
Multiple mounting methods: Magnetic design for metal surfaces, rear cross mounting holes for wall installation, Lego mounting holes, and M2 screw holes
If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.
United Kingdom consumers exercising their statutory Right of Cancellation are subject to different conditions. See the Statutory Right of Cancellation.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
A valid Return Authorisation (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A £100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tyres, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odour-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items * — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfil a customer request.
* United-Kingdom consumers retain their statutory Right of Cancellation on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Cancellation, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorisation (RA)
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
