@sarathslab why your are choosing this perticular LoRa module, can you please elaborate your use case. Personally I don't have experience with this module. When i go through the details of this hardware find like this is a UART device and so you can communicate by using the AT comments. And this will be available on the datasheet I guess. Also if you don't want to use this perticular module I suggest sx1276 or LoRa E5 from Seeedstudio. And by using this you can able to connect with helium network or things network. If you want to know more about this I think Salman can help.

@Anudeep Is that solved? if yes please share how you solved then next time we can save some time 😊

@kowshik1729 Sure, Will share more details about the Maker Summit and Introduce new maker's .

@salmanfaris I've not used the same version of the stepper motor that you've mentioned but I've used 12V stepper motor with ULN2003 motor driver. So probably I can help you with the queries.

Firstly all the tutorials on the internet show how to connect your motor's wires to ULN2003. But, in reality when you buy those motors the wires color codes may be changed, so in that case, we need to use a multimeter and check the resistance of the wires. 2 wires will have the same resistance and other 2 wires have the same resistance and the leftover one is a ground wire. This way we can get to know which wire must be connected to which port of ULN2003 driver. This is the common doubt all get while using ULN2003.

Really insightful on how to use the laser cutter, especially in projects based application
Thanks Salman 🙂

@Gladiator54 There are some case raspberry fail to boot in my experience.

insufficient power from USB Adapter -> Try y to use 2/3 Amps Adapter

Broken Micro SD Card / OS FIle -> Try another uSD card

Polymeric Fuse failure -> It's self-resetting and usually return to normal operating parameters within a finite time, in such case check any shortage in the board PCB like small wires/coppers ..etc.

You can try load a new Raspbian OS with GUI and connect HDMI Monitor, if any error occurs you can see that, keep an eye on the ACT led (Green).

@kowshik1729
We couldn't find monitor during a hackathon and it cost the majority of our time to set up pi, this was the alternative that saved us back then.

Hope it will be helpful for you to @kowshik1729

@salmanfaris yes... The repo which used by @mhmdrameez have some issue. Can't find any latest updates in that repo.
