I haven't got any numbers from itead, but from the prices that I get from mouser, we could probably save around 4$ if we skip Si7021 and external flash.
This is still more than the cheap mini clones etc. but the problem here, is that we are running in low volume batches. The setup fees for each batch is rather high, and this has to be divided out on each board in the batch.

Ps. Main page at http://www.mysensors.org/hardware/micro still says preorder but when clicking through imall has in stock.

We don't get notifications from itead, when they change the status in their shop.. So we have to check it ourself..

I have mine up and running and MYScontroller sees them.
i'm trying to send and OTA to these devices. but it doesn't seem to be working.@hek can you confirm these came with the correct bootloader to do this? i thought i read in the start of the thread it would.
when i try to send a OTA nothing happens.
anyone have this working that can comment on what needs to be done to get it working?
Thanks!

The OTA->flash requires sketches running library code from the development branch (which it isn't currently). The boards comes preloaded with the correct bootloader that supports moving firmware from flash->program memory at boot-time.
But something must load the flash over-the-air also. This requires that you:
- Compile the sketch using the dev-branch
- Enable MY_OTA_FRIMWARE_FEATURE in MyConfig.h
- Keep node awake
- Call gw.process() in loop-section (which handles the fw-update-commands in the background and resets node when a new firmware has been uploaded).
Now that I have received my board I can actually test this code I wrote a while back:). I hope it won't bee too many bugs in it.
But note that the default temp/hum sketch on these boards sleeps most of the time it wouldn't hear the fw-update requests anyway. It would probably be better to use this feature on boards that always is awake.
For more information on what is actually happening in gw-process you can look at the code that was added in this push:

It's almost too easy to setup a sensor network (for temperature and humidity) now.
solder a socket for the NRF module, a battery holder. Plug in the NRF module, put batteries in, and you have a sensor online. (I have 3 sensebenders from tiead online at the moment, together with 2 prototypes). Need to get some more battery holders, before I can make more sensors now.

I agree! I ordered 4 from the second ITead batch (I let others get their hands on the first batch because I already had a couple OSHPark deployed) and had the first sensor up and running in no time! Great job and contribution to the MySensor's community! :+1: :+1: :+1:

Thanks.. It's actually kind of fun, when I see that things I have created, actually brings value to other people.. Always been a driving force for me (no matter what I have had my hands in, whether it's software of various types,VHF radios for ships, mobile phones, bluetooth headsets, or sensor modules :) )

It's using a standard ftdi header, as used in the arduino mini pro.
About the testmode, you should hold A0 to GND, while applying power to the unit. Then it starts spewing data to the serial port.

I had meant that i put it in test mode to try and program it.
getting it in test mode worked. i could see the led blinking.however when i gave up and put the radio back on and turn it on, i guess it had actually taken my upload.
it was reporting in F now.
so i know the DTR does the auto reset, i guess upload works, but no reset and/or completed msg in the IDE.i ordered a new programmer anyway with DTR.

Hi,
I've received some boards and all working good.
I'd like to upload a new sketch to the Sensebender Micro board and I'm attempting to do this via the FTDI FT232RL USB to TTL serial converter adapter that I purchased here (http://www.ebay.co.uk/itm/221552218333).
Could someone kindly confirm the pin to pin mapping between the FTDI board and the Senseboard Micro as when I attempt to upload I receive the message:
Programmer Type : butterfly Description : Atmel AppNote AVR109 Boot Loader Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.I'm using Arduino 1.6.5 running on Windows 8.1 (inside parallels on a Mac).
Any ideas?
Thank you
Nutz
