![]() Beware, a weak power supply or an inadequate connector will cause to board to not power up. It needs a relatively beefy 3.3V power supply, capable of providing a maximum of 800mA (even though a typical power consumption is in the neighborhood of 570mA). ![]() There is provision for powering two of the oscillators externally, by removing a ferrite bead and applying power through one of the headers. The board (a 4-layer design, btw) comes with three high quality NDK NZ2520SD Ultra low phase noise oscillators. The board I bought came with the default firmware, which supports:Ī maximum 32 channels can be supported with the right firmware (not provided by DIYINHK). Plus use a cool OLED display as a VU meter. Plus I2S inputs, besides the usual outputs. Tons of channels of high-resolution audio. So, what can we do with all this horsepower you say? It’s simple. The specific chip used by DIYINHK is the middle-of-the-line XU216-512 which corresponds to some pretty serious horsepower: 16 logical cores for a total of 2000 MIPS, 512KB SRAM, 2MB FLASH. About a month ago DIYINHK released a USB to I2S interface board based on the brand new and all-powerful XMOS xCORE-200 chip.
