``Wireless Shell`` is a module, must work with other PCB boards, it belongs to “Heltec LoRa“ series, with the following features:
》CE Certificate; | ||||||||
》Main control chip ESP32-PICO (dual-core 32-bit MCU + ULP core), with LoRa node chip SX1276; | ||||||||
》RF shielding(contain a shield shell) and other protection measures; | ||||||||
》Integrated WiFi, LoRa, Bluetooth network connections, both of them are IPEX socket; | ||||||||
》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: 10uA theoretically), it is convenient for IoT application vendors to quickly verify solutions and deploy applications; | ||||||||
