Updating the Tydebox firmware:

In the event that a feature is added to the Tydebox or a bug is discovered, the firmware on the Tydebox will need to be updated.

1.  Check the FW Version number on the system info screen of the Tydebox app.

Jot this down so you can verify that the firmware was updated properly at the end. 

2. I will email you a firmware file (TYDEB00x.bin) and you will need to copy that onto

the micro SD card that was included with your tydebox. A micro SD to regular SD

card adapter was included as well. Many computers have a SD card slot on

them, if not, you may need to purchase a USB to SD card adapter.

3. Remove the micro SD card from your computer and insert it into the Tydebox bootloader

PCB included with your tydebox. The SD card is shown fully inserted to the right. The SD card

socket has a spring loaded mechanism. When you push the card in you will hear a click, once

you hear the click you can stop pushing the card in and It should be fully seated. If you need

to remove the card push it in again to release it from the socket

(the spring will push it most of the way out).

4. You will now need to plug the bootloader PCB into the back of the Tydebox. The socket

is located on the lower left corner near the plug. Pull the Tydebox slightly away from the

wall with your left hand and plug the PCB into the Tydebox with your right hand. This can

be a little tricky but once you do it once, it’s pretty easy.


PCB shown inserted here for reference.

5. Once the PCB is inserted, press the Red reset button on the bottom left. If successful, you will see the

blue status LED flash a couple of times and then stay on for about 2 seconds. Once the programming

is finished the LED will turn off. You may now remove the bootloader PCB from the Tydebox.



6. You can verify that the update was successful by checking the version number on the system info screen

on the Tydebox app. The FW Version should be incremented by one number from the number that you

started with.
