Why Choose Voiced Sample Box V9.00
Frequently Asked Questions
What chips does the Voiced Sample Box V9.00 support?
It supports WT588F series 8-pin and 14-pin chips, WTN6 series 8-pin chips, WT588F02BP-14S, and WTN6040FP-14S. The chip must be soldered onto the U1 position on the board.
What control modes are available?
The board supports 5 control modes: 1-wire serial, 2-wire serial, IIC, SPI, and UART. The mode can be selected via onboard keys or UART commands.
How do I switch control modes via UART?
Send the appropriate command via UART at 115200 baud: 7E 04 A1 00 A5 EF (1-wire), 7E 04 A2 00 A6 EF (2-wire), 7E 04 A3 00 A7 EF (IIC), 7E 04 A4 00 A8 EF (SPI), or 7E 04 A5 00 A9 EF (UART).
What audio outputs are available on the test board?
The board provides three output options: DAC amplifier output (LM4890 for 8-pin DAC chips), PWM amplifier output (WT1312 for 8-pin PWM chips), and direct PWM output for testing.
Does the board support voice file download?
Yes. The board supports downloading BIN or T3Z files to WT588E02B chips via UART commands (7E 04 C0 00 C4 EF for full replacement, 7E 04 C1 xx sum EF for single-address replacement).
How do the onboard keys work?
Press ‘+’ to increment the address and play the corresponding voice; press ‘-‘ to decrement the address. The MCU automatically detects the chip’s control mode and sends the appropriate protocol.
Can I test key-triggered chips on this board?
Yes. For high-level trigger, use jumper wires to connect high level to the test points. For low-level trigger, solder pull-up resistors on the back of the board and connect low level to the test points.
What is the BUSY LED on the board?
The BUSY LED is controlled by the onboard MCU. It reflects the playback status of the voice chip. When the chip responds correctly, the LED indicates whether the chip is playing or idle.
What is the PCB size?
The single PCB board measures 40mm × 38.3mm × 1.2mm.
What is the recommended power supply?
The board operates from 2.4V to 5.2V. Use the VCC and GND terminals on the board to supply power.
Important: The chip under test (U1) must be soldered onto the board before use – it is not pre-installed. The BUSY LED is controlled by the onboard MCU, not directly by the voice chip. For 14‑pin chips, only PWM output is supported (no DAC). For key‑triggered chip testing, avoid using PIN1 as the trigger pin. If the BUSY LED turns off during testing and the amplifier is needed, short TX and GND to force the amplifier on.
