Touch test board
About the Touch test board
Touch test board is an open source PCB design by kaine119, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 78.7 × 51.7 mm, with 28 components from 10 distinct parts.
Other key parts include the CY8CMBR3116. By type, the board carries 20 resistors, 4 capacitors, 3 connectors and 1 IC.
It belongs with the audio designs in this gallery.
From the project
poc pcbs for artsfest thing
audio-test-board consist of an I2S DAC, connected to a headphone and speaker amp.
DAC: Texas Instruments PCM5100A I2S DAC. This feeds both the headphone and the speaker amp Headphone amp: TI TPA6139A2RGTR, Speaker amp: TI TPA6211A1DGN * Headphone jack: generic 3.5mm TRRS jack with normally-closed contacts on Tip and R1
touch-test-board breaks out an Infineon CY8CMBR3116 16-way capacitive touch sensing controller into a I2C interface, and 16 touch pads. Manufacture with ENIG for best results =)
