Thanks, you are right.

Or I will build an adapter.

I solved the problem. I have soldered a 1000uf capacitor to the output of the step down modul. Now everything is ok.
I will try the beta Version.

Hi,
here are my schematic and the layout. I have build also an adapter for the rfm69 modul to use with an Sensebender Micro, because I had still place enough.

I have read it. But i didn´t find the fuse on the picture. Do you have one with both fuses? I have problems to find such fuses in this dimension in Germany. For the Varistor I have find one with 120 Jule. I think it´s ok.

Do you use both, thermal fuse and the normal fuse? I can´t see it in your picture. I don´t find a normal fuse with 0,2A in Germany.

Thanks,
I can upload this evening the schematic and the board. But my schematic is not so fine as yours. I didn´t find pinheaders with 2mm distance, so they are single pads.

Hi sundberg84,
can you maybe take a look on my board. I have rebuild it so you can use it with rfm69 and NRF24 moduls. I have build an adapter, which will stand vertical behin the HLK-PM01.
But how can I upload a picture?

Or I will build an adapter.

I will try to rebuild it in eagle for RFM69. I think the space is there for an RFM69.

Is it possible to use with RFM69 modul?

Thanks, you are right.
