87.5MHz~108MHz Dual Channel Digital Tube FM Radio Electronic DIY Kit Type C

Product View

Detail

Features:
1. RDA5807M module delivers high sensitivity, effectively shielding noise for crystal-clear audio quality
2. Real-time frequency/volume display offers intuitive operation with a futuristic tech aesthetic at night
3. Supports simultaneous charging and usage, automatically switching between lithium battery and Type-C power supply
4. Built-in 3.3V buck-boost module ensures stable power delivery and strong compatibility
5. Adjustable angle for precise signal capture, preventing intermittent reception in weak signal areas
 
Description:
The main control chip uses the STC15W408AS microcontroller; the FM radio module employs the RDA5807M, covering the global frequency range of 87.5–108MHz with high sensitivity, low noise, and strong anti-interference capabilities. The amplifier section employs the AXS2031 digital amplifier chip (not TDA2822), featuring simplified circuitry, high output power, and distortion-free operation even at voltages as low as 2.5V. The voltage regulation section utilizes a 3.3V buck-boost module, maintaining a stable 3.3V supply for the microcontroller and LED display even when input voltage ranges from 2.5V to 5.5V. This replaces the AMS1117 regulator, which causes microcontroller malfunction and display failure below 3V.
 
Specifications:
Power Supply: 2.5-5.5V
Power Sources: USB Type-C (5V) or 3.7V Li-ion battery (18650 flat-top cell)
Receiving Band: FM
Frequency Range: 87.5MHz-108MHz
Output Power: 5W+5W dual-channel
Note: Both power sources can be used simultaneously
Omnidirectional Antenna: Adjustable in any direction for optimal reception
Audio Output: Connects to headphones or an amplifier via 3.5mm audio cable
Type-C Power Port: Simultaneously charges battery during Type-C operation; automatically stops charging when fully charged
Volume Up/Down: Single short press increases/decreases volume by one level
Frequency Up/Down: Long press for auto-scan; short press adjusts frequency by 0.1MHz
Blue LED Display: Shows real-time volume level or current frequency
 
Package Contents:
Radio Kit*1 ( with or without shell according buyer choose)
