Heltec LoRaWAN ESP32 WiFi/BLE 무선 스틱 868-915mhz
(LoRaWAN ESP32 WiFi/BLE Wireless Stick -868-915mhz)
개요
- 본 제품은 Heltec LoRaWAN ESP32 WiFi/BLE 무선 스틱 868-915mhz입니다.
- ESP32 칩 및 SX1276 LoRa 칩 기반의 제품으로 아두이노 개발환경을 지원합니다.
- WiFi/BT용 3D 안테나가 지원되며, LoRa 안테나 연결을 위한 UFL 커넥터를 지원합니다.
- USB 포트를 통해 USB-TTL 시리얼 통신이 가능합니다.
특징
- Microprocessor: ESP32 (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276/SX1278;
- Micro USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures;
- 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);
- Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal 3D antenna, reserved IPEX (U.FL) interface for LoRa use;
- Onboard 0.49-inch 64*32 dot matrix OLED display, which can be used to display debugging information, battery power, and other information;
- Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
- Support the Arduino development environment;
- (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, the serial number can be queried on this page);
- 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;
