This item includes the latest verison PCB with ES9018 chip and ADP151AUJZ-1.2 ultralow noise regulator soldered, no other component included.
The second photo shows an example connection with our USB to I2S PCB and output to our headphone AMP.
The third photo shows an SMT component assembled of the first version PCB.
All component are layout with hybrid soldering pads for thru-hole and SMT component to increase diyer flexibility.
Except the following:
1) Resistor 270ohm x2 (big 1207 smt footprint size, easy soldering even for diyer with no smt soldering experience)
2) The oscillator components FB1(Ferrite bead 0805) C1(0.1uf 0603) X1 do not need to install if user uses our USB to I2S for ES9018 PCB.
The oscillator pads is universal, it fits 7050 5032 3225 and Crystek CCHD950 footprint. It also has enable pin for diyer to choose synchronous or asynchronous operation easily. It also has U.FL connector soldering pads for install to connect external oscillator module.
FB1-FB5: short or use ferrite bead 2A 600Z
The PCB runs in hardware mode(default), it also has SDA SCL routed out for Diyer to change the es9018 register if needed.
The schematic and BOM is printed directly on the PCB for diyer easier to assembly. It follows the official demo circuit for ultimate audio performance.
It is a product for diyer to enjoy, there are unlimited possibility. The PCB layout and circuit is improving from time to time, latest version of the PCB will be shipped.
ES9018 datasheet and official demo circuit is available to all buyer.
This item is in limited stock, buyer can buy 1 pcb kit each time. Please contact us if you want to buy more than three, thanks.
