Over View
WiFi LoRa 32 is a part of the “Heltec LoRa“ series, with the following features:
1
CE Certificate;
2
Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276/SX1278;
3
Micro USB interface with complete voltage regulator, ESD protection, short circuit protection, RF shielding and other protection measures;
4
Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching);
5
Integrated WiFi, LoRa, Bluetooth three network connections, on-board Wi-Fi, Bluetooth dedicated 2.4GHz metal 3D antenna, reserved IPEX (U.FL) interface for LoRa use;
6
On-board 0.96-inch 128*64 dot matrix OLED display, which can be used to display debugging information, battery power and other information;
7
Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
8
Support the Arduino development environment ;
9
(Exclusive) Supports the Arduino version of the ESP32 + LoRaWAN protocol routine provided by Heltec. This is a standard LoRaWAN protocol that can communicate with any gateway/base station running the LoRaWAN protocol (requires serial number activation, only the development of the company) The board is available)
10
With good RF circuit design and basic low-power design (sleep current ≤800uA), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
