Product Description:

The main control chip is the STC15W408AS microcontroller; the FM radio module uses the RDA5807M, with a frequency range of 87.5–108 MHz that covers most global bands, offering high sensitivity, low noise, and strong anti-interference capabilities; The amplifier section uses the AXS2031 digital amplifier chip (rather than the TDA2822), which features a simple circuit design, high output power, and the ability to maintain distortion-free performance even at voltages as low as 2.5V; the voltage regulation section employs a 3.3V buck-boost module, ensuring a stable 3.3V supply to the microcontroller and LED display even when the input voltage ranges from 2.5V to 5.5V. Unlike the AMS1117 voltage regulator chip, which causes the microcontroller to malfunction and the LED display to fail when the voltage drops below 3V.
