💬 My Slim 2AA Battery Node
-
Internal pull-up resistors have 20-50k resistance. It may be not enough.
-
For those looking to 3d print a case for this, if you cant find the right sized ducting, I designed one thats unobtrusive:

Hello, i made a few. is someone interested in these nodes in Germany? We switched to an other Home Automation (wife: you can't build something DIY in our house that is so important than a light switch ...) system and so those nodes were never used. All nodes come untested and most of them unflashed. It would be a shame if they would just lay around here. Shipping is on you, the nodes and other s no longer needed (mysensors) stuff is free. Nodes are in Germany, and i will send them via DHL. if you are interested write me a mail to aki1988 (at) me (dot) com - first come first serve.
Edit: gone -
I built a couple of these nodes last year, I used 8 MHz internal, fuses off, and a DTH22.
This a node on a dometizc network, it measures temperatur and internal voltage every 6 minutes, then it deep sleep.
I can confirm that these nodes last more that a year on 2 aa batteries.

Hello, I placed an order through the openhardware.io website with Itead last night.
They came back this morning with a ticket saying :
Your gerber file: 571bf156249971713bb044ea.zip (Normalized Name:A100151928AN_A2AGLF002A.zip) in the order #100151928 is rejected.
The reason is:
The Gerber file doesn't have outline layer , please add it and re-upload the new file , thank you.
Can you please assist as I don't really want to cancel my order.
Thanks in advance

Hi,
This board has an ICSP header. Does it mean that I can use it to burn the bootloader in a new ATMega328 chip?
I've been trying to do burn the minicore in a board with all the required capacitors and resistor but without the NRF, but without success...
Any idea?Thanks,

@joaoabs - yes!
Just as you, I burned it with as few components (like radio) as possible but that worked out for me. -
Hello,
I'm sorry to insist on this one, but I'm a bit lost....
I could understand that the recommended bootloader is MiniCore. I installed it in my Arduino IDE and after several tries-and-errors I believe I was able to burn the MiniCore bootloader by using an USBasp2 connected to the ICSP on the slim board:

Thank you.Just for reference, the parameters were:
Board: Atmega328
Bootloader: No (only worked this way, but still not sure what this means: If is already a bootloader on the chip, or if we want to write a bootloader)
Variant: 328P
BOD: Disabled
Clock: 8Mhz internal (here I think its what we want to configure on the target chip - I wasn't sure what was about because it could also have been the clock frequency of the programmer)
Compiler LTO: Disabled
Programer: USBASPAnyway, after this supposed success message, I believe I have a MiniCore bootloader in the chip and now it should be able to be programed with the AVRISPMKII (with the usb/serial programing adapter I use to program my mini-pros).
However, I'm not able to get it working. Maybe I'm choosing the wrong definitions in the arduino IDE.
As board definition, I'm using the same as when burning the bootloader:Board: Atmega328 (from the minicore subset)
Bootloader: Yes
Variant: 328P
BOD: Disabled
Clock: 8Mhz internal
Compiler LTO: Disabled
Programer: AVRISPMKIIFor instance, to load the ascii table example (for testing purposes), I get this error:
Insert Code Build options changed, rebuilding all Sketch uses 2330 bytes (7%) of program storage space. Maximum is 32256 bytes.

I just made a new case for a LiFePO4 magnetic sensor implementation of this. Thanks for the excellent work on this handy node design!

Here is a new enclosure for the My Slim 2AA Battery Node. Not as slim but the overall form factor is still small.

Hi @m26872
Congrats for the great and simple design.
I've been troubleshooting this slimnode with RFM69 radios and realized that a shunt between RFM69's DIO0 and Mega328's INT0 is required, otherwise the node will not "hear" the gateway. Even if the nrf2rmf69 board is used this shunt is required.
It seems this is a re-current issue. Although this may be solved in the PCB2.0 could it be mentioned somewhere in the page above?Thanks and cheers!
