6.1 Mechanical Drawing
Figure 6. Nucleo-144 board mechanical drawing in millimeter
This section details the mechanical layout of the Nucleo-144 development board, providing critical dimensions and component placement information.
Key Dimensions:
- Overall Width: 70.00 mm
- Overall Length (approximate): 133.34 mm
- Main Board Length: 114.30 mm
- Other significant dimensions indicated include: 48.26 mm, 15.24 mm, 18.22 mm, 6.24 mm, 20.32 mm, 16.51 mm, 42.70 mm, 50.80 mm, 3.70 mm, 2.56 mm, 45.72 mm, 63.50 mm. These measurements represent various extents and distances between components or connectors on the board.
Component Layout and Connectors:
- Top Edge Connectors: PWR-EXT, USB PWR, CN1, CN3, CN6 (ST-LINK), CN2.
- Left Edge Connectors: Header pin rows, CN4, CN5, CN11, CN12.
- Right Edge Connectors: Ethernet, RESET (CN14), CN8, CN9, CN10, CN13.
- Central Components: The main microcontroller (MCU) is centrally located. The STMicroelectronics logo and "Nucleo" branding are visible. The website www.st.com/stm32nucleo is also displayed.
- Other Components: The board features multiple LEDs (LD1-LD8), jumpers (JP1-JP7), test points (TP10), various resistors (Rxx), capacitors (Cxx), and integrated circuits (ICs) labeled U1 through U8.
This mechanical drawing is essential for understanding the physical footprint and integration requirements of the Nucleo-144 board.
