Pico Macro Keyboard PCB Design

Fresh-place the entire Pico Macro Keyboard PCB from scratch on a 100 mm × 100 mm rounded-rectangle 4-layer board. Top side priority:

Keep the top side clean and user-facing. Place the mechanical key switches in a regular macro-keypad grid with consistent row/column spacing and aligned orientation. Keep the RGB LEDs visually associated with their corresponding switches and avoid crowding the key grid. Place rotary encoders and any user-facing controls on the top side in ergonomic positions near the key grid. Place mounting holes near the board corners and keep them clear of switches and encoders. Bottom side priority:

Place the Raspberry Pi Pico / MCU module and the majority of supporting electronics on the bottom side. Group the MCU, flash, crystal/oscillator, regulator/power parts, reset/boot circuitry, USB/support passives, and decoupling capacitors by function. Keep decoupling capacitors close to their associated IC power pins, crystal/load caps close to the MCU oscillator pins, and power components clustered together. Minimize estimated routing distance between the bottom-side MCU and the top-side switches, LEDs, and encoders. Prefer moving support passives on the bottom side rather than contaminating the top-side visual layout. Placement quality goals:

Resolve overlaps, keep all components inside the board outline, preserve routing channels between the key grid and MCU area, and maintain clean edge/corner clearance. Use both layers intentionally: top for human-interface components, bottom for dense electronics. After placement, run DRC/review and report any remaining overlap, off-board, or layer-assignment issues.

Plan

#Goal

Fresh-place a Pico Macro Keyboard PCB on a 100 mm × 100 mm rounded-rectangle 4-layer board. The design must have a clean top side with a user-facing macro keypad grid that integrates mechanical key switches, corresponding RGB LEDs, and ergonomically placed rotary encoders. The bottom side should integrate the Raspberry Pi Pico/MCU module plus grouped support electronics with decoupling located near IC power pins, crystal/load caps near oscillator pins, and power parts clustered to minimize routing distances to top side components. Include mounting holes at clear board corners and ensure intentional use of both sides while preserving routing channels; finalize by performing a DRC review to report any remaining issues.

#Implementation plan

Configure PCB board properties:
1. Set board dimensions to 100 mm × 100 mm with rounded-rectangle shape.
2. Apply a 4-layer stackup with designated top and bottom sides for specific functions.
Fresh-place top side components:
1. Place mechanical switches in a regular macro-keypad grid.
2. Align RGB LEDs with corresponding switches.
3. Position rotary encoders and additional user controls near the grid for ergonomic access.
4. Add mounting holes at the clear corners of the board.
Arrange bottom side components:
1. Place the Raspberry Pi Pico/MCU module along with its support electronics.
2. Group similar components (e.g., decoupling capacitors, oscillator crystals and load caps, power regulation parts) to keep routing paths short.
3. Ensure that decoupling components are placed near IC power pins and crystal/load caps near oscillator pins.
Apply placement guidelines:
1. Use proximity and functional grouping to minimize routing distance between support electronics and top-side components.
2. Preserve clear routing channels and minimize overlaps and off-board placement.
Perform DRC and layout review:
1. Run a Design Rule Check (DRC) review on both layers.
2. Document and correct any remaining overlaps, off-board issues, or misassignments to layers.

#Success criteria

Board is configured to a 100 mm × 100 mm rounded-rectangle shape with a clear 4-layer stack up.
Top side features an organized macro-keypad grid with aligned mechanical switches, RGB LEDs, and ergonomically placed rotary encoders along with mounting holes at clear corners.
Bottom side includes the Pico/MCU and grouped support electronics with proper placement near decoupling and oscillator pins, and power components are effectively clustered.
DRC review shows minimal to no overlaps, off-board components, and correct layer assignments.
