Specification

Product details

Product DescriptionStickS3 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, empowering voice recognition and interactive experiences. It also integrates IR transmitter and receiver, a 250mAh lithium battery, making it suitable for smart home control, AI voice assistants, and IoT project development scenarios.

Download Mode

Connect the device with a USB cable and press and hold the reset button on the side of the device. When the internal green LED flashes, the device has successfully entered download mode.

Kindly Remind

EXT_5V_EN Input Power Supply Notice

The device 5V power interface can be configured as DC 5V output / input mode. The interface defaults to input mode. In this state, DC 5V power can be supplied via the Grove interface, the EXT_5V on the top Hat2-Bus, or the 5VIN interface. When configured to output mode, power input is only allowed via USB or the 5VIN on the top Hat2-Bus. Do not supply power through other output interfaces, otherwise there is a risk of short circuit and device damage.

Infrared Reception Notes

1.The infrared receiving and decoding of StickS3 must use the ESP32 RMT peripheral and does not support receiving and decoding via GPIO method.

2. When using the infrared receiver function, the speaker amplifier must be turned off; otherwise, reception will not work properly. The operation method can be referenced in the tutorial

3. Ensure that the transmitter and receiver are aligned as directly as possible, and keep a distance of no less than 30 cm between them. If the distance is too short, abnormal reception may occur.

IR Reception Notice

When using the IR receiving function, the speaker power amplifier must be turned off, otherwise IR signals cannot be received properly.

Compatibility NotesStickS3 is structurally incompatible with the following Hat series products: Hat Mini JoyC (SKU: U156), Hat Mini EncoderC (SKU: U157), and Hat 18650C (SKU: U080)Abnormal Device NoiseEarly batches of StickS3 may produce slight abnormal noise after startup, which does not affect functional use.Speaker Volume NoticeWhen 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.Precautions for UseDo not disassemble the product enclosure without authorization. Disassembly may damage the antenna PFC circuit and affect normal device operation.
