!!! tip "So many choices!"
|
|
|
|
|
There are many different options with sub-items, so you can choose what will suit you.<br>

## Required parts
|
|
|
|
|
|
|
|
|
|
1. **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.*
|
|
|
|
|
|
|
|
|
|
2. **MicroSD card minimum 8Gb class 10**
|
|
|
|
|
|
|
|
|
|
3. **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.*
|
|
|
|
|
|
|
|
|
|
4. **[Official USB-Micro Power Supply](https://www.amazon.com/Capture-Streaming-Broadcasting-Conference-Teaching/dp/B09FLN63B3)**.
|
|
|
|
|
|
|
|
|
|
5. **The Pico HID Keyboard & mouse emulator**

|
|
|
|
|
|
|
|
|
??? 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.
