Daughter board schematic
|
||||
========================
|
||||
|
||||
|
||||
Note
|
||||
======
|
||||
the schematic has been created using GNU gEDA
|
||||
|
||||
|
||||
Bill of material
|
||||
================
|
||||
Part list
|
||||
- 3mm diameter low power LED Green
|
||||
- 3mm diameter low power LED Yellow
|
||||
- 3mm diameter low power LED Red
|
||||
- PCB mounted SPST normally open push-button
|
||||
- 26 (or 40) DIL poles pin-header female connector
|
||||
- resistors (values are not critical)
|
||||
510 Ohm (3)
|
||||
16 KOhm
|
||||
1.3 KOhm
|
||||
|
||||
Mechanical design
|
||||
=================
|
||||
coordinate (0,0) is located at the PCB corner near the power supply connector.
|
||||
the X axis is along the longest side.
|
||||
|
||||
hole_x1 = 3.50 ; // hole center x offset from PCB edge (uSD side)
|
||||
LedBtn_y = device_y - hole_y - 2.5 * 2.54 + tolerance ; // Y axis center position of LEDs and button(s)
|
||||
R_Led_x = hole_x1 + 29 + 2.54 + tolerance ; // X axis center position of red LED
|
||||
Y_Led_x = R_Led_x - 3 * 2.54 ; // X axis center position of yellow LED
|
||||
G_Led_x = R_Led_x - 6 * 2.54 ; // X axis center position of green LED
|
||||
Btn_x = R_Led_x + 4.5 * 2.54 ; // X axis center position of button
|
||||
|
||||
The LEDs and the push-button are positioned on the 2.54 mm (0.1 inch) grid
|
||||
Relative to he GPIO connector pin 1
|
||||
along the X axis : -2 * 2.54 mm
|
||||
along the Y axis (in multiples of 2.54 mm)
|
||||
Green LED center : 4.5
|
||||
Yellow LED center : 7.5
|
||||
Red LED center : 10.5
|
||||
Push-button center : 15.0
|
||||
|
||||
The LEDs have a 3 mm diameter
|
||||
The top of the LEDs are 11 mm above the PCB

Case mechanical design
|
||||
======================
|
||||
|
||||
|
||||
Notes
|
||||
=====
|
||||
- the mechanical design has been created using OpenSCAD
|
||||
- the Raspberry Pi B Plus Mechanical Drawing is included for reference
|
||||
|
||||
|
||||
Design files
|
||||
============
|
||||
The main design file is "myRaspiBp.scad". It is self-documented.
|
||||
Through parametric configuration, one can generate either the bottom part or the top part
|
||||
of the case, or both parts. A fit test can also be performed.
|
||||
|
||||
Use the file "myRaspBp_Button.scad" to create the push-button.
|
||||
|
||||
The design file include "shapes.scad" for common composite shape modules.
|
||||
|
||||
|
||||
Manufacturing files
|
||||
===================
|
||||
STL files can be used directly for 3D printing.
|
||||
The following files are available :
|
||||
myRaspiBp_bottom.stl for the bottom part
|
||||
myRaspiBp_top.stl for the top part
|
||||
myRaspiBp_Button.stl for the push-button.
|
||||
