💬 RFM69(H)W Arduino Mini Pro Shield
-
@jlaraujo I am about to order sma connectors, is there anything to look for or anyone would do?
@gohan - use the same size on the connector as you have when you order the boards ;)
-
Was able to finish up the soldering, and just playing with the mocksensor sketch... works great! (not sure why my pics are sideways, they are straight on my machine :-) )
Looking at the RSSI data, this sensor seems to be about the same signal strength as my other sensors (maybe even slightly better, probably due to the shorter and more solid connections). So it seems that the performance of the radio is pretty good.
-
If you can find the size let me know, I looked on aliexpress and none are showing what is the supported pcb size. So either it is like standard for 1.6mm pcbs or I have no idea

@gohan - I have found both 1.6mm and 1mm on Ebay. Since i like to order 1mm thats what i went with SMA connector but it was way easier to find 1.6mm. I just mean a easy misstake would be to order a 1.6mm SMA connector and 1.0mm pcb. Might probably work.

I really like this design as I am looking for a small for factor RFM69 shield. One question how hard would it be to integrate a connection for a DHT22 to be able to have a small temp and humidity transmitter. I need to have about 5 of these setup in different locations sending temp and humidity back to a gateway.

@556duckvader, like @gohan referred, you can attach the DHT22 to the arduino and not to the shield.
You can make a simple PCB that will connect to the required ports for the DHT22 to operate.
If you'd like to have an even smaller footprint, try this design:

It is not yet tested in production, probably will be by the end of the week.
