Identifying U1 Pin Functions
Started implementing a plan
#Goal
- Create three PCB silkscreen labels with multi-line texts for the Audio Out, Outputs, and Inputs connectors so that users can quickly determine the pin names and mapped IO.
#Implementation plan
1. Add silkscreen text objects for each label:
1. Create a text box for Audio Out with the content:
- "GND / 3V3 / D9 BCLK / D8 DIN / D7 LRCLK"
2. Create a text box for what is labeled as Outputs/Inputs (Box 2):
- "GND / VCC / D0 ID / D2 SIG"
3. Create a text box for the remaining Outputs/Inputs (Box 3):
- "GND / VCC / D1 ID / D3 SIG"
2. Position each text box adjacent to its corresponding connector:
1. Place the Audio Out label near the AUDIO OUT connector (Z-21105110021001) ensuring proper orientation and avoiding pad coverage.
2. For Box 2 and Box 3, decide on the mapping (e.g. relating to IN1/IN2 or OUT1/OUT2) based on the board layout and place them accordingly with readability in mind.
3. Configure the text properties on the Top silkscreen layer (or as specified):
1. Adjust text size and line spacing to ensure clear readability and appropriate spacing from pads and other components.
4. Run a Design Rule Check (DRC) to ensure no clearance issues exist.
5. Confirm that the labels accurately display the pin names and mapped IO, then finalize the placements.
#Success criteria
- Each connector (Audio Out, Outputs, and Inputs) has an adjacent silkscreen label displaying the specified multi-line texts.
- The labels are oriented for easy readability without obscuring any connector pads.
- All text objects are placed on the correct layer with proper size and spacing, and pass the DRC checks.
