Frequently Asked Questions
What chips are supported by the WT588 Series Test Board V4?
It supports WT588F02A, WT588F08A, WT588F02B, WTN6040F, WT588E02B, WT588S/HXX series, and external SPI-FLASH storage chips.
What communication protocols does the test board support for downloading?
It supports IIC (for WT588F02A/F08A), SPI (for WT588F02B, WTN6040F, WT588E02B, and SPI-FLASH), and UART for serial command testing.
How do I connect the test board to my computer?
Connect the test board via the Type-C port. Set the toggle switch to ‘Burn Download’ mode, and a drive letter will appear on your computer. Simply copy the BIN file to the drive to program the chip.
What are the on-board indicators and what do they mean?
PWR: Power indicator. COPY: Blinks during burn/download. OK: Lights up on successful download. NG: Lights up on download failure. BUSY: Reflects chip busy status. WORD: Indicates double-byte key send mode for 1-wire/2-wire.
Does the test board support serial command testing?
Yes. Set the toggle switch to ‘Serial Test’ mode. The board supports UART (9600 baud) with 3.3V TTL level. You can send commands via the serial debugging assistant using the format 0x7E + Length + CMD + Parameters + Checksum + 0xEF.
What speaker output options are available?
The board provides three speaker output interfaces: DAC amplifier output, PWM direct output, and PWM amplifier output.
How do I test key functions on the test board?
The board has dedicated keys: 1-Wire (+/-), 2-Wire (+/-), SPI (+/-), and IIC (+/-). Short press to increment/decrement addresses; long press to switch between single/double-byte mode or reset address to 0x00.
Why might a download fail?
Common causes include: chip misplacement, using the wrong adapter board, toggle switch not set to the correct position, or communication errors during the burn process.
Can I use this board to download to external Flash chips?
Yes. The board supports downloading BIN files to external SPI-FLASH storage chips via SPI communication with dedicated pin connections.
What is the operating voltage of the test board?
The test board provides 3.3V regulated power via the Type-C interface, compatible with all supported voice chips.
Important: When downloading BIN files, disconnect the chip from any external MCU or Flash to prevent interference. The toggle switch must be set to ‘Burn Download’ mode for programming and ‘Serial Test’ mode for command testing. For first-time use, format the drive letter before copying BIN files. Ensure the correct adapter board is used for each chip type.
