Pico Macro Keyboard 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 the complete Pico Macro Keyboard PCB on a 100 mm x 100 mm rounded-rectangle 4-layer board. Use the top side exclusively for the user-facing macro keypad grid with associated RGB LEDs, rotary encoders, and mounting holes, while placing the Raspberry Pi Pico/MCU module along with supporting electronics (grouped by function: MCU, flash, crystal/oscillator, regulator/power, USB/support passives, reset/boot, decoupling) on the bottom side.
#Implementation plan
  1. PCB Layout Configuration
    1. Set the board dimensions to a 100 mm x 100 mm rounded rectangle and select a standard 4-layer stackup.
    2. Configure and place mounting holes at the board corners with proper clearance.
  2. Top Side Component Placement
    1. Fresh-place a clean, aligned macro keypad grid with mechanical switches.
    2. Place RGB LEDs adjacent to their corresponding switches to support individual key lighting.
    3. Position rotary encoders and other user controls in an ergonomic location close to the keypad grid.
  3. Bottom Side Component Placement
    1. Place the Raspberry Pi Pico/MCU module and its associated components.
    2. Group supporting electronics by function: MCU support, flash memory, crystal/oscillator, regulator/power, USB support passives, reset/boot circuitry, and decoupling.
    3. Ensure proximity-sensitive parts are placed near the associated pins on the Pico.
  4. Routing and DRC Preparations
    1. Preserve existing routing channels and minimize routing distances between the bottom-side Pico and top-side switches/LEDs/encoders.
    2. Execute a complete DRC and layout review to resolve overlaps, off-board placements, or layer assignment issues.
    3. Identify and report any remaining unresolved issues.
#Success criteria
  • The board outline accurately reflects a 100 mm x 100 mm rounded rectangle with a standard 4-layer configuration.
  • The top side contains a neat macro-keypad grid, paired RGB LEDs, and ergonomically positioned rotary encoders and mounting holes.
  • The bottom side successfully hosts the Pico/MCU module and grouped supporting electronics with optimized proximity.
  • DRC and layout reviews confirm minimal to no overlaps, off-board placements, or incorrect layer assignments.
