Greetings everyone,

Just wanted to give a sneak preview of some exciting new products we will be announcing soon.

These are specifically targeted for battery operations, and they feature industry-leading quiescent low power sleep mode of what I believe to be < 50nA.
Unfortunately, all three of my current meters only have uA range with 100nA sensitivity, and all three read 00.0uA when in hibernation. (Will update later with exact numbers as soon as possible).
We're beginning production on these, but here's a pic of some initial prototypes:


TLoggerFob: (Left Image)
Features:
- ATmega328P-AU running 8Mhz
- Digital I2C Temperature Sensor
- Additional Flash Memory (up to 128Mb)
- Digital Temperature sensor (I2C-based)
- HopeRF RFM69W/HW radio with
- built-in etch antenna tuned for 915Mhz
- RTC (I2C) with 256Kb of battery-backed up RAM
- Physical formatted to fit a small dual AAA fob enclosure

MiniWirelessLP-23BP: (Center Image)
Features:
- ATmega328P-AU running 16Mhz
- 3.3V LDO regulator
- MosFet power control
- Additional Flash Memory (up to 256Mb)
- SuperCap for RTC data and clock retention
- RTC (SPI) with 128Kb of battery-backed up RAM
- Tactile Reset Switch
- SMA Antenna Connector
- HopeRF RFM23BP radio

MiniWirelessLP-HW: (Right Image)
Features:
- ATmega328P-AU running 16Mhz
- 3.3V LDO regulator
- MosFet power control
- Additional Flash Memory (up to 256Mb)
- SuperCap for RTC data and clock retention
- RTC (SPI) with 128Kb of battery-backed up RAM
- Tactile Reset Switch
- SMA Antenna Connector
- HopeRF RFM69HW radio (also supports 69W)

We're looking forward to getting these out soon.

Thank you, and best regards,
Rick

Hi,

Here my comments :

-TloggerFob

Nice idea , but will be different antenna tuning or a SMA version ?
How many pins are accessible for user ?

- MiniWireless LP

Super cap is really nice.
There's one PMOS to switch all peripherals ?
What is you target price for the LP-HW ?

Hi, thanks for your inquiry.

ReE TLoggerFob:
The TLoggerFob is really just a product I've developed for a few projects that require multiple battery operated Temp sensors which pool results into a GSM bridge, which then relays data to a back end server. These are done in groups of 150-200 loggers. So this one is not really intended for public consumption, but I thought others might benefit. We will introduce one with SMA for public use, and add a few more sensors along with complete gpio access soon. Customers that want this particular one with other frequencies, can simply cut the etch and add a simple 1/4 wave monopole of appropriate length.

Re: MiniWirelessLR:
Thanks. The one I'm going in production with has a much larger supercap, so these things can be hibernating for quite some time and retain data without power. Specifications of which will follow later upon announcement and addition to web storefront.
Price TBD, but close to pricing of the existing MiniWireless line.
The one shown uses a p-channel mosfet, but some designs will have a two stage power switching with level change. Our GPS tracker uses this concept to power the GSM modem.

I'm excited about this deep hibernation, and look forward to bringing forth many more products that will be of good service to customers.
Appreciate your comments and participation.

Hi Rick,
Whoooo, it is very interesting because I'm also working on ultra low power arduino nodes. I would like to know how can you achieve 50nA in hirbernation mode, since until you don't put atmega in total power down sleep mode you can't have less than 3/4 uA consumption. I imagine you wake up the 328 with external interrupt (from RTC or RF ?) and you power down rf module using a mosfet like when you do not need it, is that true ?
I'm just curious because I think we're working on same things, I orderd an ucurrent gold to be able to measure low current even if I made one myself with other technique but it does not feet all my needs.
I've already done this low power but my technique (2 ways, one with dedicated wakeup chip, other with dc-booster enabeld only when vdd reach 2V then charge a 10uF caps that maintain idle mode). But wih this I was between 100 and 200 nA in total power down mode.

By the way, ordered lot of module in your shop, always fine. Nice to buy in your shop.

Let me know even if you want tester for your new module, I can help if you need.

Thanks Charly,
I look forward to sharing all these things in detail very soon. I just made a few enhancements from design in the pics previous posted. So I am heading into volume production with these new ones. In a couple weeks I'm going to post it and make it available for sale. We believe this is going to be a major thing for the market, so I want make sure we have at least 1K units stocked and ready for the announcement.

I'm curious about your developments as well, and very much interested in collaborating more with you soon.

Thank you for your participation in our forum.
Cheers,
-Rick

Rick,

This is very exciting. With two AAA batteries, and say, waking up and transmitting data for a brief burst once an hour, how long do you calculate the batteries to last ?

Hi Grant,

A very loooong time, but how long depends on which radio is used, power transmit level, length of message packet, data transmit rate, and what else you're doing during wake state. With such a low quiescent, it makes the consideration of discharge during hibernation, almost negligible. I'm very excited about this, and I plan to consume a large number of these devices for my own projects as well.
All the best...
-Rick

Hello Rick,
nice products Will you also be offer the SMA antenna as an option (I hope so) when we wish to purchase the MiniWirelessLP-HW modules?

Any ballpark figure for MiniWirelessLP-HW range at present?

And apologies in advance for the following feedback. I have 2 of your miniwireless rFM69 433MHz modules. Great products but personally I would have preferred a more definite reset switch over the existing tactile reset switch. I'm never sure if I have pressed the tactile switch enough and usually have to rely on the serial output of the module to let me know that it has been depressed. It's a small point to mention over an otherwise great product.

Hi Sensorhub,

Thanks, I appreciate the feedback about the tactile...that makes two of us.
Initially I felt the same way, but then became accustomed to it, and can now sense engagement from fingertip and thus no-longer have to overcompensate.
I've removed the tactile all together on some of the products as you can see in this original post.

Haven't set pricing yet, but it will be close as possible to the current MW line.

Hello Rick,
thanks for your comments.

Do you have any idea of the transmission/reception distance of the SMA based modules?

This silly 7 port USB hub with power switch per port was one of the best purchases I've made lately.
During development, I just toggle the switch for a certain port to get a reboot. Easy button.

Rick,

I've got a question question for you
How do you intend to power your low power node, by cell coin or AA/AAA with booster ?
If cell coins, did you noticed any problem with internal resistance of the coins which prevent sending data when voltage is coming from approx 2.6V or does your supercap is doing the job to avoid voltage drop other the internal resistor ?

I can comment on the tangent, that I had a project that used exotic-chemistry (http://www.tadiranbat.com/) big D cell batteries. Lot of AH capacity, but high internal resistance. So we used supercaps to provide the burst current capacity and the batteries recharged the supercaps (in series). Overall had to run for a year. Burst power consumption was like 100mA as a recall, for a fraction of a second.

There were regulatory/safety issues in air-shipping these, and high capacity Lithium-ion.

Hi Steve,

You've evaded mine and sensorhub's question

When are the low power boards going to be available?

Cheers

Glen.

I'm sorry but you misunderstood my posting. I'm not an employee of Anarduino so I don't know!

Hi guys,

Using another powering technique for low power, you can read the following article on next gen ULPNode currently under testing with success. Some explanation are also given on Low Power customization done on bootloader.

Hello everyone! Okay, it's time for a long overdue update...

Our first three product types of the low power series will be ready to begin testing this Wednesday. After a couple days of testing, we'll announce and make available for purchase. So we should have them publicly available for purchase starting next week.

My apologies for the delay, as I've been traveling overseas for the past two months, which has caused a bit of a schedule slip on things.

Best Regards,
Rick

A mini variation with a U.FL antenna connector might be appealing due to size size, low cost.
Maybe the PCB could accommodate either. Some boards also have a hole for soldering in a loose wire, no connector.

Where needed, there are U.FL to SMA and N and others, of varying gender.

http://www.l-com.com/coaxial-ufl-to-n-male-pigtail-20cm-113-mini-coax
In all these SMA connectors, mind the RP (reverse polarity) options.

There would be folks who don't want U.FL, because an onboard SMA might be used in a hole in an enclosure, as is.

Rick,

Just saw the update of the product, and I'm really excited to see that

By the way I still do not understand by what kind of magic voodoo did you succeeded to have idle mode < 50nA

I'm waiting for the release to increase my knowledge.

Nice work guys.
