Issue #2 : removed empty ref on silkscreen.
Issue #1 : thicker tracks for 5V.

Added 3D model for the encoder.
Changed standby connector to Molex KK.

Finished placement.

Re-done schematic for compatibility with Nucleo STM32L011K4.
Removed inter-board connectors.

Added M4 mounting holes.

Added image of the schematic of the legacy circuit.
Layout : created board edge, placed components.

Created symbol and footprint for the legacy 7-segment display.

Schematic : added 1M pull-up resistor on analog temperature input for sensor disconnection protection.

Schematic : corrected Arduino reset on encoder push button, added signal on the inter-board connector.

Schematic : added Arduino reset on encoder push button (modification on equipped board on original project).

Schematic : Added pull-down resistors on MOSFETs grids (modification on equipped board on the original project).
