It looked so good, but it was too good to be true. he has installed the RFM96W and not the RFM95W. on the one hand that means 13 instead of 20 dbi output, but more importantly no lora modulation!
But the solution with the MCP16251 step-up switching regulator is great and I will take on my node. such a board for lora, just for this price would of course top!
Got 2 of these boards graciously sent to me by the Author some month ago for testing.
I wanted to test them but did not had time yet, shame on me, I really need to test them 
Maybe you looked at the first link that I posted (of the AVR in stead of LORA node, sorry about changing the link) I think the used LoRa module (Semtech SX1276) is +20dB isn’t it?
If I look at https://www.semtech.com/products/wireless-rf/lora-transceivers/SX1276, it says that it has LoRa modulation. But since you are an obvious LoRa expert, and I am not, please tell me where I am wrong.
For the LoRa 868MHz, they actually use the RFM95W-868S2
Yes, I had watched the AVR version. The Lora version is great !! 
Hi!
Do yo plan to release/share the PCB design for your board?
Thanks!
I received it today. Looks very nice, in particular that you added the ground plane below the rfm. I’ll order some components and then I’ll post an update.
soldered, up and running
and already some ideas 
Hi Wijnand,
Do you still have a pcb’s available? If so, I would like to receive one
Kind regards,
I am also very interrested in such a board. Would you publish the schematics here or somwhere else?
Thomas
Hi @All
So i know @Wijnand would share his PCBs. He let us know: What's your experience with pcbs.io?
Something goes wrong with his account. I don`t know how to help. New owner of pcbs.io is https://www.makerbright.com/ ?
Is that the solution to get in contact to solve the problem?

For better use of the battery it could be used the MCP1700-300 (3 V output) or MCP1700-280 (2.8V output) to take into account the dropout voltage.
MCP1700 typical dropout voltage is 178 mV and maximum 350 mV at 25°C and load 250 mA.
Hello Mario
Great work!
One thing: I always try to avoid the linked battery holder in your blog, this spring version is very bad, maybe this is not a real issue at those low power applications, but the contact between the springs and the battery is very poor. I therefore always use some massive battery holders, like this one: https://www.aliexpress.com/item//32691749341.html
Where can we order the boards?
If you could share the files for the 3D case would be great! I could also print some if someone from Switzerland is interested in the case and doesn’t have a printer.
Thank you!
Hello my friend!
Theoretically, I can share the plans, but I’m currently working on version 2. This will be completely open hardware and so I can upload them on various platforms.
I hope you have a little patience;)
Is there anyone with experience with the CC1310? My new design (a VT-s02c module from Vincent Tang/China equipped with a CC1310 from Texas Instruments) is the next step to go to an IoT node supporting services for 10 years with a CR2032 coin cell battery (see for the concept: http://www.ti.com/tool/TIDA-00484). You can find the PCB at https://PCBs.io/share/rG9GP. Not tested yet!!!
Do those modules support LoRa modulation? The only references I found mention it supporting a modulation similar to LoRa.
