M5STACK S3 Dinmeter DIN Standard Embedded Development Board

OUTLINE

Din Meter is a1/32 DIN standard embedded development board equipped with a 1.14-inch ST7789 screen and powered by an M5StampS3 as its main controller. It features a built-in rotary encoder for precise knob position tracking. Additionally, it includes an RTC circuit, an onboard buzzer, and buttons below the screen for device interaction and alert notifications. In terms of power supply, the design supports a wide voltage input range of 6-36V DC and has reserved interfaces for a lithium battery and charging circuit to cater to various needs. Moreover, reserved PORTA and PORTB interfaces facilitate the expansion of I2C and GPIO devices. This product is suitable for applications in parameter measurement and detection, smart home control, Internet of Things (IoT) projects, smart wearables, access control, industrial control, and educational maker projects.

FCC Warning

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause undesired operation.

Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.
