@Grave - well @gohan is right, I cant fit a RFM69 module on this board.

[Grave]

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

[Grave]

Or I will build an adapter.

[Grave]

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?

[sundberg84]

@grave Sure, you can just copy it into the message box.

[sundberg84]

@grave - at first it looks really good. Hard for me on a image to check every connection but I can not see any errors.

[Grave]

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.

[Grave]

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.

@grave - sorry, I dont run Eagle anymore so I cant check them.

[Grave]

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.

[sundberg84]

@grave yes I do for both temp and current protection. I want it to be overkill when it's diy. If you follow the links on openhardware you will find the security discussion.

[Grave]

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.

[sundberg84]

@grave - I have bought my fuses from China. Im sure its possible to find on mouser or digikey,.

[sineverba]

@sundberg84 sorry for question. i'm tryng to understand the scope for the SSR Relay. Can you explain me? Is it for some kind of safe or is it governable from the Atmega? Thank you!

[gohan]

It has smaller footprint and it doesn't wear out during time like mechanical relays

[sundberg84]

@sineverba it is much to learn and instead of me trying to make a half ok job I would suggest you search SSR vs mechanical relay. I think greatscott did a great Youtube video about it.

hi, I get constantly messages Arduino: 1.8.5 (Linux), Board: "Arduino Pro or Pro Mini, ATmega328P (5V, 16 MHz)"
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0xde
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x4c
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x9d
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xaa

is this hardware problem? I select Arduino Pro Mini board setting with AVRISP mkII programmer. are these ok?

[sundberg84]

@rzylius could be a bootloader or hardware settings. I would check the reset resistor. Do you know which bootloader is on or did you manage to upload one though iscp header?

[rzylius]

@sundberg84 said in 💬 In Wall AC/DC Pcb (with Relay) for MySensors (SMD):

header?

No, I did not. I used to work with arduinos, so this is the first time I bought and try mega328p. could you advise where to find a resource with step-by-step instructions on that?
