The DH8058 music box manual provides feature list, key functions, electrical specifications, and communication protocol details.
This manual describes the DH8058 music box from Ai Le ZhiNeng. It lists 55 built‑in songs, explains the function of each control key (play, stop, volume, up/down selection) and gives the timing for key debounce. The document also details the communication protocol, showing hexadecimal command codes for music playback, LED control and volume adjustments.
Electrical specifications are provided, including a DC supply voltage below 7 V, operating voltage range of 2.0‑5.5 V, temperature limits, GPIO voltage levels, and PWM driver currents. These data help developers integrate the device into their projects and ensure reliable operation. This manual is written in Chinese.
| DC Supply Voltage (V+) | < 7.0 V |
|---|---|
| Operating Temperature (TA) | 0 ℃ to +70 ℃ |
| Storage Temperature (TSTO) | -65 ℃ to +150 ℃ |
| Operating Voltage (VDD) | 2.0 V – 5.5 V |
| Standby Current (ISTBY) | 5 µA |
| GPIO Input High Level (VIH) | 0.5 VDD |
| GPIO Input Low Level (VIL) | 0.5 VDD |
| PWM Driver Current (IPWM) at 3.0 V | 180 mA (8 Ω load) |
Press A0 to play the current song, A1 to select the next song, and A2 to select the previous song; each key has a debounce time of 12 ms.
Hex codes are used: 0x00 for music, 0xE8 for music + flash, 0xE9 for music + no flash, 0xEA for no music + flash, etc.
The standby current is 5 µA.
