Designing a PCB

Inspired by Piotr Bugaj and his TZXDuino Shield I thought I'd take his PCB design and add the 2.5mm socket and some right angle buttons and get it so it will fit into a PP9 case.
This is a whole new thing for me as I have never designed a PCB in my life or used Diptrace before. Luckily it's quite an intuitive piece of software that's easy to use. After adding a design for a PCB mounted 2.5mm and also the buttons I managed to design a PCB that should work.

Now however it's finding a reasonably priced manufacturer for a couple of prototypes before maybe a production run.

If you're interested in looking at the Diptrace and gerber file you can download them from here.


  1. what 2.5mm jack are you using?

    1. I use the standard 2.5mm mono jack that was used by all computers that had motor control.

  2. witch prorgam are you using for pcb?

  3. I'm interested in upgrading my existing pcb to add a remote socket. Do you have the wiring diagram to show where it would be connected?

    1. The ground connects to and ground pin and the main pins connect to pin 6 on the Arduino Nano. Make sure you use a 2.5mm socket.

  4. hello, where do I find the values ​​of the resistors and capacitors? thank you

    1. Are you thinking of building your own PCB version or building one in general?

      If you are thinking of building one in general then you don't need the resistors or capacitors they are already part and parcel of the LM386 module and mini SD card reader.

      There is a design flaw in this PCB in that Class 10 SD cards do not work under USB power, only under 6v or higher DC.

  5. I downloaded the zip package in this article but in the zip package, in addition to the gerber, there is a schematic, but the values ​​of the capacitors and resistors are not reported ...

    1. This was a prototype design and not really meant for production, more to test if I could do it or not.
      There are several issues with the design, such as Jack placement and button placement, also hole size as well.

New Firmwares With New Features

Thanks to the help of Rafael Molina Chasserot some new features have been added to the TZXDuino and CASDuino firmwares which has freed up some memory as well, which may lead to more features being added in the future.
A percentage counter and a timer counter have been added to all screens so that you know how much is left of a file to play and how long it has taken to load.
The OLED1306 and PCD8544 use completely new routines for the firmwares saving a lot of memory.
Folder navigation is now different. Rather than using the Menu button on TZXDuino or the Stop button on CASDuino to return to the ROOT directory, if you press the stop button when no file is playing you will go up one folder only making it easier to navigate.

The TZXDuino has had a menu added so that MSX users can set the Baud rate of TSX files so that they can load faster than normal.
A few more emulator only IDs have been fixed so that they are skipped by TZXDuino.

CASduino has had a Baud Rate of 3675 added to…

TZXDuino 1.7

TZXDuino 1.7
This fixes issues with pause lengths that we never noticed before. It should fix games like Top Gun and Street Hawk for the Spectrum and make CDT files behave as they should for the Amstrad CPC.Changes.
*Maximum pause length of 8.3 seconds due to the TimerOne library has been worked around.
*ID20 Pause Block fixed.
*Temporary fix for pause after motor control removed.!aEt1VJKZ!ZFw-fP3bkNTtiPlbG_IllmR94Xni3KvIGUn6Jggfof8

UEF Playback added to TZXDuino

Thanks to the work of Kernel Crash we have added uncompressed UEF playback to TZXDuino. This means that Acorn machines can be added to the list of computers that can use TZXDuino. There is standard mode and a Turbo mode that can be switched on in the menu. The turbo mode loads at 1500 baud and does improve the loading time on an Acorn Electron. There is also a 1550 and 1600 option in the TZXDuino.h file but not all Electrons can handle the faster speed.

You can read Kernel Crash's blog here.

You can download the TZXDuino 1.11 from here.
