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 and layout the Pico Macro Keyboard PCB on a 100 mm x 100 mm rounded-rectangle 4-layer board. Top side will be reserved for the user-facing HMI, including a carefully aligned macro-keypad grid of switches, per-key RGB LEDs, ergonomic placement of rotary encoders and additional user controls, and mounting holes near clear board corners. The bottom side will host the Raspberry Pi Pico/MCU module and grouped supporting electronics with close decoupling, crystal, and power placement, while striving to minimize routing distances to the top side components. After placement adjustments, all overlaps, off-board items and layer assignments issues must be resolved or documented using DRC review.
#Implementation plan
  1. Board Setup and Configuration
    1. Configure the board as a 100 mm x 100 mm rounded-rectangle with a 4-layer stackup.
    2. Place mounting holes at the clearly defined board corners.
  2. Top-side Placement for HMI Elements
    1. Place the macro-keypad grid by positioning switches in an aligned layout.
    2. Associate and place per-key RGB LEDs in close visual proximity to each switch.
    3. Position rotary encoders and additional user controls ergonomically near the macro-keypad grid.
  3. Bottom-side Placement for Electronics
    1. Position the Raspberry Pi Pico/MCU module and all supporting electronics on the bottom layer.
    2. Group supporting components by function (decoupling, crystal, power regulation) and ensure minimal routing distance to corresponding top-side controls.
  4. Overlap and Routing Issue Resolution
    1. Perform a check to resolve any overlaps, off-board placements, and inappropriate layer assignments.
    2. Run a Design Rule Check (DRC) and review the layout.
    3. Report any remaining issues related to overlap, off-board placements, or layer-assignment constraints.
#Success criteria
  • The PCB is a 100 mm x 100 mm rounded rectangle with a properly defined 4-layer stackup.
  • Top side contains a neatly aligned macro-keypad grid with corresponding RGB LEDs, rotary encoders, and user controls.
  • Bottom side successfully houses the Raspberry Pi Pico module and grouped supporting electronics with optimized decoupling, crystal, and power placement.
  • All overlaps, off-board, and layer-assignment issues are resolved or documented after the DRC review.
  • The DRC report verifies that the layout complies with the defined design rules and constraints.
