@nca78 Thanks for the info, Il try it today!
Works like charm!
@Nca78 Thanks! I'l check what you suggested.
If I would use:
i would need to
And if i use:
5v power supply
i would need to:
@Nca78 Thanks a lot for a quick and detailed response.
I tried last night with the regular nmodule pcb (without battery part) and that one didn't work either (seems like the ones that were working before were connected to 5v power supply, not 12v).
Arduino led is at full level and radio is not connecting.
Please confirm that you see this picture:
Should this pads be connected like this? C7 and C6 are connected, not sure if its the problem with the manufacturing or is it meant to be connected?
Another question is: should I connect pads in YELLOW or RED direction? (probably stupid question)
So far I connected them in yellow direction C7->C7
Could this be connected with the problem?
If this 12v does not work out, do you have any other advice?
What I want to do is to use your design without batteries.
It is very small and will fit into a wall socket where I would connect it to some DC power supply.
This DC powersupply will be converted from 220V AC to 12V or maybe 5v.
If I use 5v powersupply, can I still connect 3,3v arduino and sensors to it and how would be the best way?
Thanks a lot!
@Nca78 I didn't soldier JPOWER either.
Problem is that when I connect 12v to terminal block, my voltage regulator gets very hot and arduino is just showing red led ad not responding to reset.
If I try to connect FTDI cable to upload a sketch, I got my CAP on arduino fried as you can see in the image.
If I try the same thing on simple nmodule (without battery part), it works when I push 12v to RAW and GND.
Maybe the battery pcb part is making problems? Should I soldier C4...C9 on the back of the nmodule pcb?
@Nca78 Hi, looks like I am doing something wrong in my last attempts to use your design with 12v external power supply.
I am using:
As you can see on a picture, I am using a terminal block where i push 12v.
When I connect the power to the terminal, my Voltage regulator get veeery hot and nothing works.
When I connected my FTDI to try to upload a sketch, a capacitor on arduino got fried. You can see it in the next pic.
This happened on tree of my boards.
Can you please take a look and try to see where the problem might be?
connect 12v as a power source from usb breakout.
Do you power the board from 12V or 5V ?
thanks for a very quick reply. I am trying to use a 12v external power source to power the arduino + radio + nmodule board. I tried soldering AMS1117 3,3V to the BRD part of the nmodule board, but when I connect my 12v (+ to the RAW pin and - to the ground) I do not get the regulated voltage at the nmodule shield breakout.
In essence I would like to make my nmodule board work without batteries, by using external power source (usb breakout that is connected to android 12v adapter). This 12v would be regulated by AMS1117 that I solder on BRD part of the board. This way both arduino and radio would get 3,3v and nmodule board would push that voltage to the shield trough vcc and gnd. Maybe I am looking at this the wrong way?
This the quote on your OpenHardware page that I am using as a guidance:
"footprint for an AMS1117 regulator (light blue) if your source voltage is too high for Arduino (> 5.5 V or > 3.3V for 8MHz version). AMS1117 can handle up to 15V and 800mA but it consumes a lot of power, so this regulator should be used only for "wired" power (12V, USB, ...) and never with batteries. If you are using only this regulator, the capacitor of the radio should be enough to keep it stable, but if you want to be on the safe side, you can use the capacitor footprints on the other side of the board: C6/C7 for input C8/C9 for output."
I managed to make my double AAA version to work without problems and kudos for great work!
@nca78 Hi, I am trying to use nmodule without batteries and connect 12v as a power source from usb breakout. I am not sure if I should remove the voltage regulator from pro mini? Also, should I add my own regulator to the nmodule (on BRD section)? Where should I connect my + and - from usb breakout to the nmodule? Thanks alot!
