StickS3 is a compact and high‑performance programmable controller designed for remote control and IoT applications. It is powered by the ESP32‑S3‑PICO‑1‑N8R8 main control chip, supporting 2.4 GHz Wi‑Fi wireless communication, with 8MB Flash and 8MB PSRAM to meet diverse application development needs, delivering excellent performance and scalability. For human–machine interaction, it features a 1.14" LCD display, a 6‑axis IMU sensor, and programmable buttons. The audio system adopts the ES8311 mono audio codec, combined with a high‑sensitivity MEMS microphone and AW8737 power amplifier, enabling clear audio capture and high‑fidelity audio output, empowering voice recognition and interactive experiences. It also integrates an IR transmitter and receiver, along with a 250mAh lithium battery, making it suitable for smart home control, AI voice assistants, and IoT project development scenarios. Input Power Supply Notice: The Grove interface at the bottom of the device can be configured as DC 5V output / input mode. The interface defaults to input mode, in which DC 5V power can be supplied via the Grove interface, the EXT_5V on the top Hat2-Bus, or the 5VIN interface. When configured as output mode, input is only allowed via USB or the 5VIN on the top Hat2-Bus. Do not supply power from other output interfaces, otherwise there is a risk of short circuit damage to the device. IR Reception Notice: When using the IR receiving function, the speaker power amplifier must be turned off, otherwise IR signals cannot be received properly. Speaker Volume Notice: When powered by battery (USB not connected), it is recommended to keep the speaker volume below 75% to avoid unexpected device reboot caused by excessive power consumption.
