And believe it or not, the LoRa version can be had for as little as $15.99 each with Prime delivery:
https://www.amazon.com/gp/product/B01LHTU14W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1Yeah, at that price I think this becomes a buy, not build, decision.

if i remember well, the adafruit board is SAMD21G.
Here another example, sort of feather i made a while for testing SAMD21E. The same it's rechargeable, and I added some features like a rgb led, sma connector for RFM69/95, flash, signing, MYSX etc..
mounted with a weather extension board i made. If there is an interest, i can clean a bit my files and upload it, it's working well ;) -

Argh. For only a little more than what I paid for the Sparkfun SamD21, I couldn't have gotten the same MCU with an RFM69HCW! And it's already on a 2-layer board, not a 4-layer board:

@NeverDie @Nca78 oki noted!
@Terrence yeah, agree too. i have assembled one for testing as it was new and not available. Unfortunately, regarding Mysensors use, there are no flash for ota (in case for future), no signing, no eeprom for routing table (atsam has no eeprom, only emulation if i remember), no sma connector ... -
@NeverDie I love the Feather boards. Currently working with the RFM69 feather. Build in battery connector/charger is very nice to have.

Good to hear! :) I ordered one today (after my posting above). There's a good chance I'll receive it on Sunday. I look forward to trying it out.

Well so one of you brilliant guys will come up with a FeatherWing that will add all of that functionality right? :thumbsup:
-
@Terrence and no usb goodies for protection. woops can't be added on an external board :) I'm kidding, well, i let others make this featherwing, enough busy on my side ;)
-
@Terrence that's a bit OT ;) yep among others things, and i'm quickly distracted so i need to stay focused :)

Have you found a cheaper source than Amazon for buying them?

@NeverDie No, Adafruit is the maker/seller and before just recently you had to buy them from them and pay the shipping and slow order fill process.
I have Amazon Prime, so shipping is "free" and they show up in 2 days.
I have never seen them for lower than MSRP.

Just discovered this, bought with no wifi (no need for it) and usb adapter. It's using a SAMD21E17 (so 16k/128k) but should be enough for playing a bit and I love the stackable usb adapter that you need to buy only once for all your boards.

What do you guys think of the NRF51822?

The dev boards are really cheap, and they come with a capable mcu. -

What I find even more interesting than that, though, is "extended range" Bluetooth, which might very well be the all-in-one tiny module that does it all: http://www.cypress.com/blog/psoc-creator-news-and-information/design-long-range-bluetooth-applications-new-ez-ble-psoc-xtxr
No need to add an NRF24L01 or an RFM69 module, because for home automation, the extended range version of bluetooth should have adequate range already. And it has a capable ARM MCU built in. -

I have the nRF52840 Preview DK, but have not fired it up yet. Still trying to understand how to code Bluetooth.
http://www.nordicsemi.com/eng/Products/nRF52840-Preview-DK.SiLabs has an interesting Gecko BT5 chip as well.
