We not only invest time in the project. You don't want to know how many Wemos or other components are already in the garbage can. Or measuring devices. If something "ticks", you can't figure it out without, for example, a logic analyzer (about 550€) or an oscilloscope. In short: This covers your own costs a little. Let's not even talk about the many evenings and nights that we have to spend when there is an "urgent" problem somewhere.

For those who would rather have a finished board rather than sourcing and soldering everything themselves, we now offer finished and tested boards as a solderless DIY kit at. So we can finance the whole thing halfway. These are then already loaded with the latest firmware.

The proceeds from the sold circuit boards are used for the further development of existing and new projects.

All sets are available in the versions Wemos D1 Mini and/or D1 Mini Pro (ceramic antenna or external antenna) and/or as a pure circuit board without Wemos.
