2nd Generation Hardware Platform

ESP32 Processor with built-in WiFi and UART interfaces

The first version of RepPanel supports a less compact hardware platform (HWv1) and was developed and released on GitHub for free more than a year ago. Since then, I added support for a more compact and capable hardware module that is developed by wireless-tag. Developing and testing such a firmware takes many months.
That is why I decided to link the firmware support for the improved hardware platform to a small fee.
Since it is very cost and time intensive to sell hardware, I decided to sell the RepPanel firmware only. This also makes it more convenient and cheaper for you, since you can source the hardware from your local supplier.

Give it a try directly in your browser. No download, no installation necessary. Experience the ease of use and benefits RepPanel will bring to your printing workflow firsthand.

How to Buy

A full RepPanel build requires the RepPanel firmware (the software) and the supported hardware module. You will need to buy both separately to get RepPanel running.

Frequently Asked Questions

It is called: WT32-SC01

The module is manufactured by wireless-tag and sold internationally. Sometimes it is advertised as a Seeed Studio product.

Beware that you might need to pay import tax if you order the module from a seller outside your economic zone.

In short: The GitHub version is deprecated and requires you to build your own hardware. The here advertised HWv2 version supports a readily available hardware board that is ready for use. The new hardware also reduces the response time of the UI. The old hardware could only display 16 items per directory, whereas the HWv2 can do much more (>50 items) due to memory-optimized drivers. It also features hardware and software optimisations that notably increase the performance and stability of RepPanel. The HWv2 version is smaller and more compact than the GitHub version.


The GitHub version is so to say RepPanel v1. They share the same software core, but the more recent feature updates and support for improved hardware are only available on the HWv2 version available from this page. This includes bug fixes, babystepping, driver fixes etc.
The here advertised RepPanel HWv2 version is also the only version with active support. The GitHub version is deprecated and no longer developed.

By only selling the software I am able to reduce the price of RepPanel for customers significantly. It allows me to focus on the software while letting others handle the high costs involved with electronic hardware (import tax, (international) shipping, returns, refunding, disposal fees, FCC certification etc.)
Selling and shipping hardware in Europe/internationally requires you to obtain CE/FCC certifications, pay WEEE disposal fees and a lot of logistics. The fees can end up in the thousands even for small batches. Selling hardware becomes a numbers game and the financial, logistical and bureaucratic efforts stand in no comparison to the expected revenue if you do not go “big time”.
Example: Selling hardware + software would lead to an end price (at least) 4x-6x higher than the purchasing price of the hardware. Selling only the software and letting the bigger players handle all the cost intensive stuff allows you to conveniently buy at your local distributor while still saving a lot of money overall.

The license allows one individual to install RepPanel on up to five hardware modules for private use. Commercial use is limited to one installation per license. I do offer discounts on license purchases of 1+. Just contact me.

For private use you can install RepPanel on up to five devices per license. For commercial use, only one installation per license is allowed.

I am working on it and it looks promising, however I cannot guarantee support at this stage. Images are very memory consuming and the hardware offers only a few kB of RAM.

Yes, just contact me. If you have purchased a license, I am happy to give you access to the source code. You can modify it as you please, just don’t release it publicly.
