Other key parts include the DAC8568BIPW (JLC global sourcing), ADS131M08IPBSR, OPA4172IDR, PCM3168APAPR and OPA1679IPWR. By type, the board carries 42 capacitors, 22 resistors, 17 ICs, 4 connectors, 4 diodes and 3 inductors.

It belongs with the audio and power & battery designs in this gallery.

From the project

DIY DC-coupled USB interface for Circuit Studio (parked design: ESP32-S3, PCM3168A, DAC8568/ADS131M08)

An ESP32-S3 display board (LilyGO T-Display-S3) on a factory-assembled carrier PCB. The computer sees a normal USB Audio Class 2 device plus a USB-MIDI port; BLE-MIDI works without a computer. Jouni only solders through-hole parts.

Plus: MIDI->CV mapper on the P outputs (USB-MIDI and BLE-MIDI), a status display (meters, USB/BLE/calibration/power), USB-C power as the main supply, optional Eurorack +-12 V and LiPo.
