SMD Version
This project is designed for experienced users with expertise in soldering small Surface Mount Device (SMD) components. While we do not provide a soldering kit for this version, you can download the complete KiCad project and assemble it independently. If soldering small SMD components is beyond your current skillset, you may want to explore building the Through-Hole Technology (THT) version as an alternative.| Here is a link to the kicad project on Github |  |

THT Version
If you have a bit of soldering experience, you should be able to build this version. It uses only THT components (Through-Hole Technology), and the components should be readily available. If you are technically up for the challenge, you can download the KiCad project, order the PCB, and build it yourself completely. We also offer a soldering kit containing the PCB and all components. You can't go wrong with this one.| Here is a link to the kicad project on Github | |

Development Version
This version makes it easy to develop your own applications. The ZIF socket facilitates quick swapping of the EEPROM, and the ESP32 is on headers, making it replaceable if needed. We use this design ourselves during the development of the chat cartridge. Of course, it can also function solely as a chat cartridge.

| ESP32 SOURCE CODE |  | |
|---|---|---|
| The ESP32 source code was written in the Arduino IDE. You can download the code from our GitHub page, here is a link: |
|
| Here is a manual explaining how to update the ESP firmware | |
| Assembly source code |  | |
|---|---|---|
The assembly program code was written and compiled using Kick Assembler. You have the option to either download the ASM code and compile it yourself, or download pre-built binary files. These binaries can be directly flashed into an 8k EEPROM.
