Khadas Tone2 Maker Kit development board

SKU CH-1DJX-6H2JP

Hi-Fi DAC development board with ES9038Q2M chip supporting PCM 768 kHz and DSD 512 native, plus balanced RCA outputs and shielded analog circuits

  • XMOS XU208 8-core processor delivers PCM 768 kHz and DSD 512 native playback
  • Shielded analogue circuits block electromagnetic interference for consistent audio quality
  • 40-pin 2.54 mm GPIO header enables direct connection to VIM boards after soldering female connector
  • 14-pin 0.5 mm FPC header links to VIM3 or VIM4 via T2V extension board
  • 4-pin 1.2 mm VIN input accepts external power supply for flexible deployment

Audio development kit for makers

The Khadas Tone2 Maker Kit is a high-fidelity digital-to-analog converter built around the ES9038Q2M DAC chip. It processes PCM up to 768 kHz and native DSD512 through an XMOS XU208 controller with 8 cores and 208 threads. Analog circuits are protected by an EMI shield for consistent signal integrity. The kit targets developers and DIY enthusiasts building custom audio hardware.

Suits embedded audio projects and OEM evaluation

Engineers prototyping Hi-Res audio endpoints or evaluating the ES9038Q2M for production designs will find the expansion headers and optional VIN power input useful. OEM customers can access MQA-licensed firmware variants. Buyers who need a finished consumer DAC with a chassis, volume knob, or headphone amplifier should look at completed desktop audio products instead.

Dual GPIO and FPC headers define host compatibility

A 40-pin 2.54 mm GPIO header connects to VIM1S, VIM3, and VIM4 single-board computers after soldering a female connector onto the Tone2. A 14-pin 0.5 mm FPC header links to VIM3 and VIM4 through a separate T2V Extension Board. Verify which header matches your host board before purchasing.

Questions about this item

Will the Tone2 Maker Kit's 40-pin 2.54 mm GPIO header connect directly to my VIM3 board?

The 40-pin header matches VIM3, but you must solder a female connector onto the Tone2 board first; the kit ships with male pins only.

How can I verify the ES9038Q2M DAC is decoding DSD512 natively after setup?

Play a native DSD512 test file and check your player software shows the sample rate without DoP conversion; the XMOS XU208 reports the stream format to the OS.

What cables or accessories are included in the box versus what I must buy separately?

The box contains the Tone2 Maker Kit board, an instruction manual, and a warranty card; any GPIO female header, FPC cable, T2V Extension Board, or external 1.2 mm VIN power supply must be purchased separately.
