Default ES9023+WM8805+PCM2707 TINY DAC

This is a tiny DAC measuring 45 x 35 mm in dimension yet it is a full fledge DAC with spdif and USB receiver. The DAC and receiver has onboard power supply regulators. The DAC and receiver board can be stacked one over the other. The LEDs on the receiver board will show signal lock status. The onboard clock can be turned off if needed. The dac board has provision to work either at 3.3v or 3.6v. Super compact size, it will fit in any case. The assembled DAC photos shown below is for reference only.

DAC+RECEIVER PCB - $10 (two boards)

ES9023 DAC IC - $4

HCMOS CRYSTAL - $2.5

INTERNATIONAL REGISTERED AIRMAIL - $6

PAYPAL CHARGES - $0.624

PM WITH PAYPAL ID IF INTERESTED

I do not offer a build version, buyers have to assemble it by themselves.

You should be able to make one for $45 or less. If you want you can use only wm8805 part and can omit the pcm2707 and vice versa the cost will further come down. Not each channel for one board, two channels for one board. I need at least 25 people for the group buy, the order will not be processed until that number is reached. I will just keep a log of the people who are interested, so you just need to send in the PayPal ID if you are interested and you will get a PayPal invoice only if 25 people are reached. Same is the case with ES9018 single IC and dual mono DAC boards, I need minimum of 10 people for single ic and 5 people for dual mono DAC group buy if they want es9018 DAC chip and crystal soldered on the board. Names of all people taking part in the group buy will be posted on the respective thread once the above mentioned group buy limit is reached.

ES9018 single chip and dual mono dacs doesn't come with WM8805. Single chip ES9018 DAC will cost around $165 to make and dual mono will cost around $220 to make
