A quick overview of what you'll need before starting your PSPi 6 build.

## PSP 1000 Parts Needed

The PSPi 6 is designed exclusively for the original PSP 1000 series. It replaces the motherboard inside, so you'll need a donor PSP to source the shell and other reusable components.

### Supported PSP Cases
- **PSP 1000 Series Only**
  - Compatible with original fat PSP 1000 series
  - Includes models: PSP-1000, 1001, 1002, etc.

### Incompatible Models
- **NOT** compatible with:
  - 2000 series
  - 3000 series
  - E1000 series

### Required Parts from Donor PSP

You'll reuse the following parts from your donor PSP:

1. **Shell** - Front and back casing. Genuine PSP shells are recommended as aftermarket versions tend to be lower quality.
2. **LCD Bracket** - Metal bracket that holds the LCD and retains the back cover.
3. **Control Panel** - Located on the LCD bracket, includes the Display, Mute, and Volume buttons.
4. **Power Board** - Houses the power switch and LEDs on the right side of the shell.
5. **D-pad** - The directional pad assembly.
6. **Button Membranes** - Rubber membranes under the buttons.
7. **Shoulder Buttons and Membrane** - The L and R trigger buttons.
8. **Internal Speakers** - The original PSP speakers.
9. **Joystick and Rubber Interface** - The analog stick and the rubber interface underneath.
10. **WiFi Antenna** - The stock PSP WiFi antenna is compatible with CM4.

> It's best to buy a complete broken PSP 1000. The motherboard and LCD will be replaced anyway, so they can be broken or defective.

## Raspberry Pi Options

### 40-pin Models

The following Raspberry Pi models fit directly into the PSP shell:

| Raspberry Pi Zero | Raspberry Pi Zero W | Raspberry Pi Zero 2W |
|-------------------|---------------------|----------------------|
| ![Raspberry Pi Zero](components/raspberry_pi_zero.webp) | ![Raspberry Pi Zero W](components/raspberry_pi_zero_w.webp) | ![Raspberry Pi Zero 2W](components/raspberry_pi_zero_2.webp) |

Pi 3 and 4 are electrically compatible with the PSPi 6 board but physically too large to fit inside the PSP shell. Pi 5 is also pin-compatible, but not recommended because of power requirements.

### Compute Module 4

#### CM4 (with eMMC)
- Slightly faster bootup
- Fixed storage size (no flexibility)
- Cannot use SD card

#### CM4 Lite (no eMMC)
- Uses SD cards for storage

Both require the CM4 Carrier board for installation.

### RAM Considerations

- **For Emulation:** Any RAM amount is likely sufficient for retro gaming.
- **For Full Operating Systems:** At least 4GB RAM on CM4 is recommended, with more being better for multitasking and heavier applications.

### Performance Comparison

| Feature | Pi Zero | Zero 2W | CM4 |
|---------|---------|---------|-----|
| Gaming | 16-bit era games well, struggles with PS1/N64 | Smooth 16-bit, many PS1 games play well | Wider emulation compatibility, plays PS1 and many PSP games |
| Battery Life | 4-18 hours depending on usage | 3-12 hours depending on screen brightness | 2-4 hours normally, up to 6 hours in some cases |

> The Pi Zero 2W is my personal favorite, balancing performance and battery life well.

### PSPi 6 Board

The main board of the project.

- **Order from:** [othermod.com](https://othermod.com/product/pspi-6-board/)

### Battery

The board uses a standard JST PH 2.0mm connector for 3.7V LiPo batteries.

- **Order from:** [othermod.com](https://othermod.com/product/generic-2000mah-lipo-battery-w-2-pin-jst-ph-connector/)

### LCD

The PSPi 6 uses an aftermarket 4.3" 800×480 LCD driven directly from the Raspberry Pi's GPIO pins. The original PSP LCD is not compatible due to pinout and resolution differences.

## Optional Accessories

### CM4 Carrier Board

This adapter board lets you use a Compute Module 4 in your PSPi 6. It provides a solder-free setup for CM4 installation.

- **Order from:** [othermod.com](https://othermod.com/product/pspi-6-compute-module-4-carrier/)

### Headphone Board

This board enables headphone use with the PSPi 6. It uses pogo pins to make contact with the PSPi 6 mainboard, so no soldering or wiring is required.
