- or LGT 8F328 with pre-loaded firmware, can support upload arduino sketch normally.
On Board Flash Storage:
- On board SPI flash 8M-bit for data
- Supported by arduino SPI flash library. (or low power spi flash library from lowpowerlab)
- You must disable if you want to make it low power, so only turn on when you use it.
Battery Charging:
- On board MCP73831 battery charger IC.
- Board can be powered by lithium battery, and charge when 5V power supplied to board.
- On board power LED, and backside charge status LED.
- Battery voltage level monitoring can be read via A7 analog pin.

Battery polarity connector is inverted.
Chao (store manager) –
Yes, sorry for this issue, the very first 20pcs of our stock was built wrong, we should emailed every customer who get this wrong one, please notice.

Ricardo Meechan –
I received five units with the LoRa module included however the modules have a shield over them – Does this mean they are the 868mhz version or do the 433mhz also include a shield on the module?
Chao (store manager) –
Hi, add shield for all version, better against noise.
Ricardo Meechan (verified owner) –
I now have 10 units will the 433mhz module pre-soldered and will be purchasing more soon. They work well with the RadioHead libraries and have been running for a couple of weeks now on one 18650 li-ion battery – i have removed the power LED and use methods to powerdown the radio and Arduino. I still need to check the power consumption during sleep and will report back. It would be nice if it was possible to monitor the battery voltage similar to the Ada Feathers. Also they run at mhz so program as 8mhz Pro Mini. 🙂
Chao (store manager) –
Hi, yes currently sending version has voltage monitor now from two days ago … on A7 pin.
But this time missing the charge status LED on the back, probably concern the power use but actually it won’t light up when not charging, we are bad organized and has this missing and imperfect, accept all refunds or review if you are not happy with it. Will add this back as final version soon.
Have an example code here – https://github.com/Edragon/Arduino/blob/master/Sketchbook/02_LORA/rf95_reliable_datagram_client/rf95_reliable_datagram_client.ino

Looks like a great little board but the documentation (schematic) is not accessible from your link. The schematic that I see online doesn’t show the SPI flash, so it’s not complete.
David Goadby –
These are just what I need for a largeproject so I have just ordered a pair. But, like previous posters, I cannot get access to the schematic. Can someone sort this out please? Poor information and support can kill a very good product.
Bernard Banitz (verified owner) –
Excellent card tested with 5km transmission distance in a lorawan network
torntrousers (verified owner) –
I’m just getting started, seems like a good board so far. Re the inaccessible schematic Michał Szymański mentioned – I emailed them and within just a few hours they replied giving me a userid/password to access the schematic. Also, i missed it initially as its underneath what looks like generic SX1278 doc but there is info on the board here: https://www.electrodragon.com/w/SX1278#Loraduino
Chao (store manager) –
Hi, Any question just put here on review or email us, or forum if you prefer. Thanks!
sagram (verified owner) –
Excellent. only i have question how to put this into low power mode, I have 200uA in low power mode, after i remove voltage regulator, led,memory ,and battery regulator
sagram (verified owner) –
some more tweak .based on https://github.com/dragino/Arduino-Profile-Examples/blob/master/libraries/Dragino/examples/LoRa/LoRa_Mini_Low_Power/LoRa_Mini_Low_Power.ino low power now is 22uA
Chao (store manager) –
Have to google, http://www.home-automation-community.com/arduino-low-power-how-to-run-atmega328p-for-a-year-on-coin-cell-battery/
This is a library for it, power down to low power mode, then wake up later by interrupt pin D2 D3.
We will have another low cost board for this in this week or next, also the board now has back charging led from now.

Hi, Im new to Arduino and lora. Is there any tutorial about how to upload code to loraduino?
Chao (store manager) –
Hi, Choose Arduino pro mini 3.3V/8M as board, and upload these two sketches to two board:
rf95_reliable_datagram_client
rf95_reliable_datagram_server
https://github.com/Edragon/Arduino/tree/master/Sketchbook/02_LORA
You can test the module.
urs –
so, since the schematic is still “not accessible” for 8 month I’ve to ask here
a) do you still hilde it 🙁
b) is the layout compatible with a Hope RFM95W with 868MHz?
thanks
Chao (store manager) –
Dear customer, It is not hide, just only provide for customer, I have just you wiki login info email, please check.
Not sure if it is compatible with RFM95, we don’t have this module to test.

Hi Chao,
These boards are working fine, I used them quickly with LMIC on TTN without any problem (wiring DIO1 to D4)
May I suggest some improvement:
– Burn Optiboot bootloader from https://github.com/MCUdude/MightyCore, this will save 1.5K of Flash that is very important since LoRa stack takes some place, this will keep uploading features with also Pro Mini 8MHz 3V3, no compatibility issue.
– Change the 2 x 10K resistors of voltage divider for battery measure by 2 x 470K resistors, this will decrease consumption of this divider from 180uA to 3.8uA.
– may be add another button to do some action
regards
Chao (store manager) –
Hi Charles, Will upgrade these features, the first comment should be very helpful, will test this. Second one we already have a few customers asked this, will replace the them on next batch production. Will check the necessarily for the button, also if enough space to add it. Thank you!

Please fix the schematic link.
I have logged in with the credentials from the tracking email but is still inaccessible!
