M5Stack GP8413 Dual-Channel I2C DAC Unit

The M5Stack DAC2 Unit converts digital commands into two independent analog voltage outputs. Built around the GP8413, it provides 15-bit resolution and supports 0–5V or 0–10V output ranges for embedded control, signal generation, LED dimming, power-supply references, and industrial analog interfaces.

The host communicates through I2C. Hardware address selection supports addresses from 0x58 to 0x65, with 0x59 as the default. This allows up to eight devices to share a bus for as many as 16 analog output channels when the full system is planned correctly.

Generate Two Independent Analog Voltage Outputs

Use each channel for a separate control or reference signal. The product specification lists output voltage error below 0.2% and linearity error of 0.01%, but final system accuracy also depends on load impedance, supply quality, wiring, calibration, temperature, grounding, and downstream equipment.

Selectable 0–5V or 0–10V Range

Choose the output range according to the receiving equipment. Confirm the input limits and common-ground requirements of the connected controller, inverter, dimmer, power supply, or analog interface before applying a signal.

Multiple I2C Addresses for Expansion

Address selection through A2/A1/A0 supports multi-device expansion. Before adding several units, check bus pull-ups, cable length, address configuration, power budget, and startup behavior so outputs do not enter an unintended state.

Short-Circuit Protection Is Not Complete System Protection

The unit includes output short-circuit protection, but the surrounding system still needs appropriate wiring, current limits, grounding, transient protection, and fail-safe behavior. For safety-critical motion or process control, use independently rated protective controls.

Technical setup details are available in the M5Stack DAC2 documentation.

How can I confirm product compatibility?

Check the product specifications, operating voltage, communication interface, dimensions, connector type, and software requirements before ordering. Compatibility may also depend on your controller, operating system, development framework, library version, and project wiring.

If you are unsure, contact us before purchasing and include your controller model, intended application, power source, and any other hardware you plan to use. We will help you identify the most suitable option, but we cannot guarantee that every product will work with every platform or project.

Does the product come with a warranty?

Warranty coverage may vary by product and manufacturer. If your order arrives damaged, incomplete, or appears to have a manufacturing defect, contact us as soon as possible with your order number, product model, and clear photos or videos of the issue.

Our team will review the information and provide the appropriate next step according to the applicable product and after-sales policy. Damage caused by incorrect wiring, unsuitable voltage, unauthorized modification, soldering, misuse, or operation outside the documented specifications may not be covered.

How long does shipping take?

LogicBoundless provides worldwide shipping, with primary service coverage across the United States, Europe, and Asia. Orders are generally fulfilled from Shenzhen, China, and tracking information is provided after dispatch.

Processing and delivery times depend on product availability, destination, customs clearance, and the selected shipping service. Please review the Shipping Information page for the latest estimated delivery times and shipping conditions.

What is your return policy?

Eligible products may be returned within 30 days of delivery. Returned items must be unused, unsoldered, unmodified, and kept in their original condition with all packaging, cables, accessories, manuals, and included components.

Please contact support@logicboundless.com before sending anything back. Returns made without prior approval may not be accepted. Original shipping charges are generally non-refundable unless the return is caused by a verified product defect or fulfillment error.

Can you help if I have a technical problem?

Yes. LogicBoundless provides practical technical guidance for product setup, wiring, power, communication, code, and configuration issues.

To help us understand the problem efficiently, please provide your controller model, wiring photos, power source, code, library or firmware versions, expected behavior, and complete error messages. We cannot promise that every component will work in every system, but we will help you identify the likely cause and the next practical troubleshooting step.

Can I change or cancel my order?

Contact us as soon as possible if you need to change or cancel an order. We will try to assist before the order enters processing or is handed to the shipping carrier.

Once an order has been packed or dispatched, it may no longer be possible to change the products, delivery address, or shipping method. In that case, the standard return process may apply after delivery.
