M5STACK Atom EchoS3R Highly Integrated IoT Voice Interaction Controller
Description
Atom EchoS3R is a highly integrated IoT voice interaction controller specially designed for intelligent voice control and human-computer interaction scenarios. At its core is the ESP32-S3-PICO-1-N8R8 main control chip, which supports Wi-Fi wireless communication and comes with built-in 8MB Flash and 8MB PSRAM, meeting the diverse application development needs and providing excellent performance and scalability. The audio system employs the ES8311 monaural codec, combined with a high-sensitivity MEMS microphone and NS4150B power amplifier, to achieve clear sound pickup and high-fidelity audio output, enhancing the voice recognition and interaction experience. It is suitable for voice interaction scenarios such as AI voice assistants and smart home control.

FCC STATEMENT
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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.
IMPORTANT NOTE
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 to 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 the general RF exposure requirements. The device can be used in portable exposure conditions without restriction.
