Description
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 built-in 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. It also integrates IR transmitter and receiver and a 250mAh lithium battery — ideal for smart home control, AI voice assistants, and IoT development.
The Grove interface at the bottom of the device can be configured as DC 5V output / input mode. 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 — risk of short circuit damage.
When using the IR receiving function, the speaker power amplifier must be turned off, otherwise IR signals cannot be received properly.
When powered by battery (USB not connected), keep speaker volume below 75% to avoid unexpected device reboot from excessive power consumption.
