If you want to try out a Cheap and Easy arduino sensor you can find a BB-FRM9x-x on ebay and a atmel328p-pu.

My focus was to find a cheap, easy to program and low current solution for everyone ...

The BB-FRM9x-x do have a voltage regulator so it means that you can supply with 3.6 volts to 5 volts.

I can get it down to 13uA with 3.6 Volts in sleep mode.

RHF76-052 Lora module is born to be a serial LoRa module with firmware made for communication with an other uC.

But inside are an SX1276 and an STM32L051C8T6 and with the LMIC filesystem it is no problem to use this module with your own software

link to ebay where you can buy the module

I did make a simple test print on my CNC just to do all the test.

I did get one of these boards link to page where to buy and checked out where to find som LoRaWan code for it.

Could not find anything but only som code here link to github BSFrance

Arcording to the datasheet it can run LoRaWan Link to datasheet

I did want to test this little Lora Node because of the STM32L151 and on the board there is a holder for litium battery.

Here you can find code for stm32CubeIde and the lmic library Link to ZIP file

In our MakerSpace we did install a Lorix One gateway LINK

it was very easy to get running thanks to this link

I did buy a Heltec HT-M01S Indoor LoRa Gateway because having to much trouble with the IC880A

The price was good and it works VERY fine ....Up and running in 10 secunds ..

link to heltec

There is a lot of gateways out there and in my search i found the multichannel IC880A from IMST.

VERY Well documented and easy to get working. I did use an old Raspberry pi 2 because i did have one which was not in use.

You find the hardware information here IC880A gateway link and buy it here IC880A shop

Looking for a cheap gateway i did find the LoRa Go Dock.

You can use it as a gateway for your own testing because of the single channel.

it is based on arduino code and you can find the code here GIT LoRa Go Code - The guys did a great job ;o)

STM32H7 DCIM OV2640 and DMA2D to LTDC screen on stm32cubeide

You can buy the board at ebay link to ebay

I did use the files from waveshare as a start link to waveshare files

There is a clock issue and thts why the camera sometime make funny picture - I will make a new version when i do find the deep reason.

You can buy the board here link to ebay stm32h743iit6

You can find all the schematic and some samples code here waveshare link

You can find datasheet om the screen here link to waveshare
