# Building the Hardware to Run UPIWIN
|
|
|
|
UPIWIN is designed for a hardware configuration with a miniature capacitive-touch touchscreen mounted on a
|
|
Raspberry Pi computer, making for a compact assembly. This document describes how to assemble one.
|
|
|
|
## Parts List
|
|
|
|
- Raspberry Pi 3 Model B+ computer
|
|
- PiTFT Plus 320x240 2.8" Capacitive Touch Touchscreen (Adafruit part number 2423)
|
|
- Pi Model B+/Pi 2 Case Base - Clear (Adafruit part number 2253)
|
|
- PiTFT Faceplate and Buttons (Adafruit part number 2807)
|
|
- 2x Brass M2.5 Standoffs (Adafruit part number 2337)
|
|
- Additional Raspberry Pi hardware (MicroSD card, power supply, keyboard and display connections)
|
|
|
|
## Assembly Instructions
|
|
|
|
1. On the back of the PiTFT, solder closed the jumper pads labeled "#18". This will allow the use of GPIO line 18 as
|
|
a PWM backlight control.
|
|
2. Attach two standoffs to the underside of the PiTFT (pointing in the same direction as the 40-pin connector), on the
|
|
right side (the side with the pushbutton switches). Secure with the included nuts.
|
|
3. Attach the PiTFT to the Raspberry Pi, pressing down hard to seat the 40-pin connector atop the Pi's GPIO pins.
|
|
4. Seat the completed assembly inside the case base, lining up the holes for the USB and Ethernet ports on the left
|
|
side. Press down to snap the latches into place.
|
|
5. Holding the faceplate upside down, insert four plastic buttons into the four small rectangular slots. Invert the
|
|
case assembly and snap it together with the faceplate, lining the buttons up with the pushbutton switches.
|
|
6. Connect the Pi to keyboard, display, power, and network (if necessary). Insert the MicroSD card with the operating
|
|
system installed, and boot as usual.
