Introduction: LoRa E32 Device Arduino Shield (8Km Support)

Software developer but I love electronics, wood, nature, and everything else as well.

E32-TTL-100 is a wireless transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and penetration ability of the module improved more than 1 times compared with traditional FSK.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Here the Module

You can find module here AliExpress (3Km) - AliExpress (8Km)

Step 2: Arduino UNO Shield

I create a Library an Arduino shield very usefully to use.

The configuration is this:

LoRa_E32 e32ttl(4, 5, 3, 7, 6);

Than you can use all examples inside the library, you can use pin 6 and 7 to do a full connection or disable they and put M0 and M1 as you want with dipswitch.

Step 3: Start Prototype the PCB With CNC

As already I say I do a tutorial on how mill PCB and how to build CNC and I use that to create my prototype

Step 4: Than Test With Logic Analyzer My PCB

Step 5: Now We Are Going to Do a Massive Production.

Ready to go

Step 6: Shield Description

The shield have some jumper and dip switch to configure M0 and M1.If you want set M0 and M1 to a fixed value you must put jumper to F, if you want control via pin to P.If you set to F you must put dip switch on property value Low or High.

Step 7: Shopping List and PCB

You can get my PCB shield here from PcbWay.

Step 8: Here My Crtistmas Present

I chose this manufacturer because at the same cost it offers excellent quality, in the first screen it is possible to make countless options suitable for every need.

Step 9: Here the Soldering Video.

Step 10: Here the Result

Step 11: Thanks
