LTS5 LoRa HMI Touch Screen

LTS5 is a (% style="color:blue" %)LoRa / LoRaWAN HMI Touch Screen(%%) designed for display purpose of IoT project. It have a 5.0" HMI touch screen, and support WiFi, Bluetooch, LoRa wireless protocol.

22

23

LTS5 is an Open Source software project. The MCU is ESP32 and Dragino LA66 LoRa module. There are lots of development source for ESP32 which can greatly reduce the development time.

24

25

The HMI touch screen of LTS5 supports drap & drop design. Developer can use SquareLine to easily customize the display UI for different application.

26

27

LTS5 use LA66 LoRa module, this module can be program to support private LoRa protocol or LoRaWAN protocol.

== 2.1 How it work? ==

79

80

81

Each PB01 is shipped with a worldwide unique set of LoRaWAN OTAA keys. To use PB01 in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After this, if PB01 is under this LoRaWAN network coverage, PB01 can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is** 20 minutes**.

82

83

84

== 2.2 How to Activate PB01? ==

85

86

87

(% style="color:red" %)** 1. Open enclosure from below position.**
