Heltec Wireless Shell 모듈 -LoRa+WiFi+BLE
(Heltec LoRa+WiFi+BLE Module -868-915MHz)
개요
- 본 제품은 Heltec Wireless Shell 모듈 -LoRa+WiFi+BLE 입니다.
- ESP32-PICO 와 SX1276 LoRA 노드 칩을 기반으로 디자인되니 제품입니다.
- RF 쉴딩이 되어 있으며, IPEX 안테나 커넥터를 가지고 있습니다.
- WiFi, LoRa, Bluetooth를 지원하며 아두이노 개발환경을 지원합니다.
- 아두이노 버전의 ESP32 + LoRaWAN 프로토콜을 지원합니다.
특징
- MCU:ESP32-PICO-D4 (240MHz Tensilica LX6 dual core + 1 ULP; 600 DMIPS, 520KB SRAM, WI-FI, dual mode Bluetooth)
- LoRa chip: SX1276
- LoRa frequency: EU_433, CN_470_510, EU_863_870 US_902_928 four frequency bands are optional
- LoRa signal maximum output power: 18 ± 2dB
- Hardware Resources: UART x 3; SPI x 2; I2C x 2; I2S x 1 12 – bits ADC; 8 – bits DAC 44 generic GPIO
- FLASH: internal 4MB (32M-bits) SPI FLASH
- Interface: LoRa Antenna (IPEX) x 1; Wi-Fi/BLE Antenna (IPEX) x 1
- Dimensions: 38.4 x 16.1 mm
- Controllable external device power output (Vext) √
- Low power design:Deep sleep mode current 10
- (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: 10uA theoretically), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
