WisBlock RAK2305 ESP32 Wi-Fi and Bluetooth Module

The RAK2305 adds 2.4 GHz Wi-Fi and Bluetooth to a WisBlock node. At its heart is an Espressif ESP32-WROVER with PCB antenna, 4 MB flash and 8 MB PSRAM. The core module controls the RAK2305 via UART with Espressif's AT commands; custom firmware can also be flashed.

WisBlock from RAK Wireless is a modular system for building custom LoRaWAN and IoT nodes. Core, sensor and IO modules are plugged onto a base board and screwed in place.
