Just want to add a note about the ftdi usb to TTL, it should be capable of 3.3V, as this is the operating voltage of the board.

gloob

Is there any idea when the pre-order phase will be over and the production and shipping will start?

tbowmo

@gloob

According to itead they would start shipping 20th of may.

gloob

Will it be preloaded with the temperature/humidity functionality, that I only have to attach the NRF24L01 module and the gateway will automatically detect it?

Currently I don't own a programmer to upload programs. I did only work with arduino nanos with a USB Interface.

@gloob

Yes, it will be preloaded with a sketch reporting temperature and humidity level using the auto assigned id from controller.

My ISP programmer uses 5V. Is it compatible, if I remove the NRF24L01+?

tbowmo

@FotoFieber

It depends, if you are supplying the board from the ISP programmer, then Si7021 and the external flash will die very quickly, as they are not 5V tolerant..

My congratulation! It is very cool stuff!
Why not to post this thread http://forum.mysensors.org/topic/510/minimal-design-thoughts to the useful links on iteadstudio product page?

Great stuff! Boards ordered....!

FotoFieber

Yes, great stuff, ordered 6... wish they were available 4 weeks ago: I wouldn't have designed a minimal PCB/NRF based on the DIL version of the 328,,,,

Just ordered 6 for myself. I wouldn't want to miss out on the first batch. Only around 100 left.

Talked to Itead today. They had to source the ATSHA204A from overseas and will start production when they arrive.

RJ_Make

Picked up 5 myself

What would be the best option to add an external temperature sensor to the Sensbender Micro?
Another Si7021? Any thoughts?
I could not find any other I2C temperature sensor with the same voltage range to a reasonable price.

bought also 3 pieces :-)

mvader

I picked up 3 and 5 radios

hetbeest

Just ordered two to start with ;)

Hope this isn't too silly a question.... The temp/humidity sensing, that works 'out of the box' without requiring me actually connecting these sensors, right?

And another question, would it be possible to turn the temp/hum function off and just have a motion sensor connected which would never do anything unless it sensed movement and then send a message to the gateway?

I've been flat out at work for a couple months so I've been away from this for a while... :-)

@Dean

It will be programmed by the factory, with the "Sensebender micro" sketch, https://github.com/mysensors/Arduino/blob/master/libraries/MySensors/examples/SensebenderMicro/SensebenderMicro.ino

So it's plug'n'play as a sensor with temperature and humidity. You could always dump another sketch to the unit, if you want to use it for something else.

gol

I have also ordered a couple of boards to be able to evaulate them as soon as possible.

Just a question:

What is the expected lifetime of the batteries if you use 2 AA batteries, the default preloaded sketch and reports the temp and humidity values once per minute?

Out of curiosity, can over the air updates be implemented on Arduino Nano? I'm going to get 3 to put Sense to the test. :smiley:
