You now have your new Rasptendo Case. Now it’s time for you to assemble and configure it along with your Raspberry Pi 3 to transform it into the Rasptendo retro gaming console.

The Rasptendo Package Box comes with

  • Rasptendo Case
  • 2 male to female USB extender
  • POWER and RESET Button PCB Board
  • 6 labeled female to female jumper wires
  • 2 male GPIO header
  • Installation guide
  • heat sink

The POWER button issues a safe shutdown command to your Raspberry Pi to prevent damage to your SD card. For the RESET button, you can have two (2) options – one for the soft reboot, and one for the hard reset.

Option 1 for the RESET button issues a soft reboot, which is the safe way (for your SD Card) of rebooting. It’s the same as issuing a sudo reboot in the terminal. It’s especially useful when you transfer ROMs via WiFi and you have to reboot for the RetroPie to discover the newly transferred games. The minor downside to this option is that if your Raspberry Pi hangs (which happens rarely), the button won’t work. That is why we have the second option – which is the hardware reset. It’s useful when your Raspberry Pi hangs a lot – but if it does, then that game is probably not intended to be played in your Raspberry Pi. But we’re giving you the option by the way. You have to keep in mind that Option 2 is only a slightly better version of unplugging and plugging the power source to your pi, which means it’s still a little risky for your SD card.

Step 1 (Skip when opting to Option 1)

  1. Solder the 2 male GPIO header to the P6 headers (labeled RUN) on your Raspberry Pi 3 board.

Step 2

  1. Insert the 2 male to female USB extender to your Raspberry Pi 3. Mount the other end of the extender to the USB slot in the case. Attach the heat sink to the Pi’s CPU.
  2. Without the Micro SD card inserted, screw your Raspberry Pi 3 at the 3 screw points at the bottom of Rasptendo Case (see illustration below)

Step 3

  1. Connect the other end of POWER SW jumper wires to the pins in the PCB labeled POWER. Connect the other ends at Pins 5 (GPIO3) and 6 (GND).
  2. Connect the RESET SW jumper wires to the pins in the PCB labeled RESET.
    Option 1. (NO SOLDER) Connect the other ends to Pins 13 (GPIO27) and 14 (GND).
    Option 2. Connect the other ends to the P6 headers (the ones you soldered labeled RUN)
  3. Connect the POWER LED+ jumper wire in the PCB labeled LED+. Connect the other end in Pin 8 (GPIO14).
  4. Connect the POWER LED- jumper wire in the PCB labeled LED-. Connect the other end in Pin 9 (GND).
  5. Screw the top component of the Rasptendo Case to its base.

Step 4

  1. Insert your Micro SD Card in your laptop, then download the image of RetroPie in Make sure to download the Raspberry Pi 2/3 version since you are going to install it on your Raspberry Pi 3.
  2. After downloading the .gz file, extract the file using your favorite extraction tool. Remember the directory where you extracted the .img file.
  3. Download the Etcher software and install. Click Select image then navigate to the extracted .img file. Click Select drive then choose the SD card. Click Flash! then wait for the process to finish.

Step 5

Now that you have assembled your Rasptendo game console, it’s time to install and configure some files for the POWER and RESET buttons to work. Fortunately, you can do this via online with a one line install using wget and bash in the Terminal.
1. Connect your Rasptendo console to a monitor and a keyboard before powering your Raspbery Pi.
2. Connect your Rasptendo to the internet. You may access the internet via LAN or via WiFi. (To configure your WiFi via Terminal follow this tutorial.)
3. Access the Terminal of your RetroPie by pressing F4 upon boot up.

In the Terminal, type the following command:

wget -O - "" | sudo bash

This will run a command that will automatically configure your Raspberry Pi 3 to access the Rasptendo Console POWER button. Your Raspberry Pi will automatically reboot in order for the changes to take place.

Step 6

After your Raspberry Pi has rebooted, test the Power button by holding it for a second. The LED will start blinking followed by your Raspberry Pi shutting down. You can turn on your pi by pressing the Power button again.

Raspberry Pi State Action Function
ON long press (>= 1 s) shutdown
ON short press (<1 s) nothing
SLEEP short/long press wakes Pi

  1. Recalbox / batocera instructions?

    1. We’ll come up with a Blog on recalbox soon.

      1. Hello! but does it normally work in the batocera / recalbox the power and reset buttons? I want to buy but I’m in doubt.

        1. hey Paulo, I’m working on it right now. It’ll come up pretty soon haha

  2. I am interested in buying, but I live in Brazil and do not have an international card. would you like to generate a purchase in the ticket and send by FEDEX or DHL? can create sale by aliexpress?

  4. HI, i’m interested in this product but you don’t talk about an eventual cooling system. Using the Rapsberry for emulation make it really hot… Is there any solution for adding a cooling system in this case ?
    Thanks !

    1. Hello Karnam, there is still enough space in the case for a miniature cooling fan powered through your GPIO power pins. Unfortunately we are not selling cooling fan units for now, but this one by Adafruit for example is a good option.

    2. There is enough space for you to place a fan in case you would like an active cooling system. We’ll make a post on this soon.

      1. Thank you two for the reply, i’ll wait to see that post for more informations !
        Unfortunately bisgetti your link doesn’t seem to work.

        1. Hey sorry, fixed it now.

  5. Ill you be selling these through amazon?

  6. Hi, Do you have any plan to create SNES PAL/Superfamicom version?

    1. Hi Burm, we’re looking into it.

  7. Before any one asks it – ’cause there’ll probably a lot of similar requests – do you plan. To release a Japanese/Europea-PAL edition ?

  8. Don t sent to Brazil?

  9. My Rasptendo case arrived damaged. How can I contact support? Thank you.

    1. Hi! Please email us the details at

      1. Thank you very much. You guys took care of the problem and fixed everything for me. Thank you!

  10. Could you please provide info on how to wire up a fan? It seems that the necessary ground pin is taken by the power switch.

    1. You can split the wires and connect to a different ground pin. Check out the different ground pins here

  11. Normally, Rapsberry has 4 USB doors, for 4 controlers.
    The Rapstendo has only 2 USB? Thanks.

    1. Yes, that is correct.

  12. How would one set up this case with a dual heatsink fan such as this one:

    The fan uses gpio pins, and so does the functional power buttons on the case. I watched an eta prime video that mentioned rewiring if using the dual heat sink fan and this case.

    Any guides would be appreciated, or advice. Thanks in advance!

    1. Hi Kyle, these fans have two wires for GPIO pins, one for the 5V pin and one for the Ground. There are two 5V pins (namely Pins 4 and 6) in the Raspberry Pi and lots of Ground pins. To use this fan, you have to split the wire so you can put the other wire in pin 4 (or 6) then the other one at a Ground Pin. Check this out so you you know what Ground Pin to use (I recommend Pin 39), GPIO tutorial

      1. Thanks Rasptendo! Can you guys please make a post with this tutorial? Even if it didn’t have pictures like the main setup tutorial, I think a LOT of people are going to be wanting to do this, so it would be a good idea to make a dedicated post for it!


        I love my Rasptendo case!

        1. It looks like so! Expect the blog post this week. Thanks for the feedback Brandon!

  13. My Reset button does not do anything, I did the solderless install. Any tips or troubleshooting ideas? The power button works but reset does not.

    1. Can you check again if it’s in the right GPIO pin? If yes, I recommend you read the manual installation instructions.

      If it still doesn’t work please let me know!

  14. Hello, while my retropie seems to be working fine, I get this error ( every time on startup before it boots into emustation. Can anyone explain what exactly it means? It only appears when I put in the configuration for the POWER and RESET buttons found on your directions. I restored my SD card to its prior state which did not have the POWER and RESET configuration and the error does not appear. But when I put in the config again, the error pops up again. It doesn’t seem to effect anything, so I am wondering how I can remove or hide this error. I am no technical guru, as I mostly followed the directions found on youtube videos on how to setup retropie. I did two retropies and only one is giving this message. Any help would be appreciated. Thanks!

    1. When you did two retropies without the warning, did you use different Raspberry Pi’s? The warning is harmless although I imagine it’s annoying. The problem might be hardware since we just knew about this now and no kind of issues like this so far with different pi’s.
