The Green Hat (as well as other hats and the IOTT stick with with they work) are great, and great fun. Hans is a wonderful contributor to the electric model train hobby, and a great educator. I should add that it appears that he is providing these items to us a the cost of the components - with nothing added to cover his design work and software! (Documentation is in his YouTube video - which are a much watch for their own sake).

Great product and design, integrates with almost everything.

For YellowHat for the IoTT Stick

Implementation is superb, works as expected, easy to configure and use. Allows integration with other modules, LocoNet (both command station based and stand-alone, both wired and wirelessly) plus converts LocoNet to DCC commands. Did I mention that it also works with JMRI and Node-Red? And it does this all at the same time.

Fabulous products for the RR modeling community.

For IoTT Stick

The IoTT stick is inexpensive and powerful with the esp32 and wifi included. But the software developed by iott is revolutionary. It is combining modern internet of thing technology like Mqtt protocol dcc, loconet and neopixel « ws2812 » addressable led for layout signaling. Imagine driving as many signals as you like with a chain of only 3 wires. The iott stick is easily programmable using a simple comprehensive web page accessible with any browser. This is a great product and with a lot of hardware and software improvements planned for the future. I highly recommend taking a look à this product and all related video on YouTube.

Great neopixel driver for the model rr modelers

For BlueHat Signaling and Lighting for the IoTT Stick

I am currently experimenting with this neopixel led driver to create my own signaling system on my layout and control panel. Having all the signals target addressable and daisy chain them with only 3 wires is a revolutionary idea for the model railroad community. It is using easy available inexpensive components. I am hoping to be able to use this system to drive all the leds of my layout eventually. So far I have try it with a neopixel led band and individual 5mm addressable led. I will order shortly miniature board to try to drive regular led as well. So far It is working as advertised on his YouTube channel. I highly encourage you to take a close look at this product for your model railroad. And the yellow hat device.

Nice 3D printed enclosure.

For Enclosure for DCC breakout board

The enclosure is well designed and do job protecting the circuits. Just wish to get a 3D printer for my need.

The dcc breakout board is working great

For DCC Interface Breakout Board with Grove Port

The board is communicating flawlessly with my NCE dcc system. The only draw back i can find is software related. when we use it We do not have Mqtt communication like the loconet board. I would love that it can do a relay mode with Mqtt. I don’t think the full gateway is necessary. Let see how the software improve over times.

That actually is a great idea. There is no reason why I could not feed the DCC information to MQTT. I will put it on the to do list for an upcoming version of the stick software.
