# DIY PiKVM V1 Instructions
!!! tip "So many choices!"
There are many different options with sub-items, so you can choose what will suit you.< br >
However, we marked the recommended way by sign ** `✮ ✮ ✮` **
-----
## Required parts
1. **MicroSD card minimum 8Gb class 10.**
2. ** [Official USB-Micro Power Supply ](https://www.amazon.com/Capture-Streaming-Broadcasting-Conference-Teaching/dp/B09FLN63B3 )**.
3. **Raspberry Pi board:**
* **[✮ ✮ ✮ Raspberry Pi 3](https://www.raspberrypi.com/products/raspberry-pi-3-model-b/)**.< br >
* ... or [Raspberry Pi 2 ](https://www.raspberrypi.com/products/raspberry-pi-3-model-b/ ).< br >
*Does not support H.264 even with HDMI-CSI bridge.*
* ... or [Raspberry Pi Zero 2 W ](https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/ ).< br >
*Compact and cheap, but not so reliable solution because of lack of the wired Ethernet.
Note that the better way to use Pi Zero is making [PiKVM V2 ](v2.md ) - it supports more USB features.*
4. **Video capture device:**
* **[✮ ✮ ✮ HDMI-CSI bridge based on TC358743 chip](https://www.amazon.de/Waveshare-Raspberry-Supports-Backward-Compatible/dp/B092HVP926/)**.< br >
*Supports H.264 video encoding on Raspberry Pi 3, automatic resolution selection and the lowest possible latency.*
* ... or [HDMI-USB dongle ](https://www.amazon.com/Capture-Streaming-Broadcasting-Conference-Teaching/dp/B09FLN63B3 ).< br >
*Only heavy MJPEG video, no resolution detection, big latency compared to HDMI-CSI.
Some users report hardware problems: the dongle may not work in the BIOS or simply stop working after a while.
It's a black box, and no one knows what's inside it. If you have problems with it, it will not be possible to fix them.*
5. **The Pico HID Keyboard & mouse emulator:**

6. **Board-specific parts:**
!!! success "✮ ✮ ✮ "Nothing special for Raspberry Pi 2 or 3"
??? note "Raspberry Pi Zero 2 W"
??? note "✮ ✮ ✮ HDMI-CSI bridge"
* *x1* [Raspberry Pi Zero Camera Cable ](https://www.amazon.com/Arducam-Raspberry-Camera-Ribbon-Extension/dp/B085RW9K13 ). *Not compatible with Auvidea B101* .
??? note "... or HDMI-USB dongle"
* *x1* USB-A socket to USB-Micro adapter (female-male).
7. **Optional features:**
??? success "✮ ✮ ✮ ATX controller to manage the target host's power"
{!_diy_parts_atx.md!}
??? note "PS/2 Keyboard & mouse"
The use of PS/2 is intended for advanced users. Check out the additional list of details in advance
in the [corresponding paragraph ](pico_hid.md#ps2-keyboard-mouse ) of the Pico HID manual.
??? note "VGA video capture"
If you want to capture VGA from your server instead of HDMI,
buy the [VGA-to-HDMI converter ](https://aliexpress.com/item/3256801728005613.html ).
Some converters have issues with not supporting all resolutions and refresh rates.

## Setting up the hardware
1. **Video capture device:**
??? success "✮ ✮ ✮ HDMI-CSI bridge"
{!_diy_setup_video_csi.md!}

??? note "Raspberry Pi Zero 2 W"
Connect the USB dongle to USB-to-Micro adapter, and connect it to the USB port marked as `USB` (not `PWR` )
on the Pi Zero board.
2. **The Pico HID and ATX controller:**
Connect all the parts according to this scheme:
??? success "✮ ✮ ✮ With ATX controller"
