Parameter Screen Specifications: 1.9-inch 320×170-pixel IPS display Bluetooth Name: Bluetooth Audio (can be changed by the user) Bluetooth Version: V5.3+BR+EDR Bluetooth Range: Approximately 10 meters FM Reception Range: Standard: 87.0–108.0 MHz Germany: 87.5–108 MHz Japan: 76–90 MHz Full Coverage: 76–108 MHz Audio DAC Hardware Bit Depth: 32-bit 3.5mm Headphone Jack Audio Channels: 2 channels (Stereo) 3.5mm Headphone Jack Audio Signal Level: <2.5 Vp-p 3.5mm Headphone Jack Audio Output Signal-to-Noise Ratio: SNR ≤ 104 dB 3.5mm Headphone Jack Output Signal Power: <50 mW Speaker Audio Output Port Signal Power: ≤3 W (Supports only one small speaker of approximately 3 W; this port carries a mixed left-right channel signal, not a stereo output) Operating voltage: 3.3–4.5V Standby current: <1μA Operating current: 50–1000mA (approximate range; power consumption varies by state and volume; does not include peripheral current) Port Descriptions 1. 3.5mm Headphone Output Port: This is a stereo audio output port that can be used to directly plug in 3.5mm headphones or connect an audio cable to an amplifier. 2. TF Card Slot: Used to insert a TF card to play music files stored on the card. 3. Type-C Port: This port serves as a combined charging and USB sound card interface. It can be used to connect a Type-C cable to a charger to charge the battery, or to connect to a computer as a USB sound card for playback. 4. 3.7V/1000mAh Lithium Battery Port: This is the module’s power input port, designed for a 3.7V/1000mAh lithium battery. (Note: Connect the end marked “+” to the battery’s positive terminal and the end marked “−” to the negative terminal.) Since the charging current on the board is set to approximately 250mA, it is only suitable for charging a 3.7V/1000mAh lithium battery. We do not recommend using batteries of other capacities to avoid mismatched charging currents. The input voltage range for this port is 3.3–4.5V. Be careful not to exceed the maximum voltage rating of 4.5V, and do not reverse the polarity of the power supply; otherwise, the module will suffer irreversible damage.) 5. 3W Speaker Output Port: The board integrates a 3W audio amplifier for connecting a small external speaker of approximately 3W. (Note: This port only outputs the audio signal from the left and right channels mixed on the board and amplified by the amplifier; it can only drive a single speaker. If you need to drive two speakers for stereo sound, you must use the stereo signal from the 3.5mm headphone jack and connect it to an external amplifier.) . 6. FM External Antenna Solder Pad: This port is used to connect an external FM telescoping antenna. The recommended antenna length is approximately 30–80 cm. (Note: The antenna solder pad and the screw hole above it are connected. Simply select one of these points and connect it to the telescoping antenna via soldered wires or other methods.)

Important Notes 1. Please use a 3.7V/1000mAh lithium battery to power this decoder board (we recommend purchasing the bundle). The Type-C port on the board is for charging only; do not use the Type-C port as the sole power source without connecting a battery. The battery input voltage range is 3.3–4.5V. Do not exceed the board’s maximum voltage rating of 4.5V, and do not reverse the polarity of the power supply, as this may cause irreversible damage! 2. Do not use the FM radio function while charging, as the charger operates in a high-frequency switching state that can cause high-frequency ripple interference with the radio, resulting in squeaking noise or signal interference that prevents reception. 3. Technical guidance for DIY modifications is not provided with this product. Buyers who to modify the speaker themselves should assess their ability to do so before purchasing. label:yes
