RAK4631-R WisBlock LPWAN Module, nRF52840 & SX1262 w/ RUI3

Imagine you need a tiny brain that can talk to the cloud, sense the world, and stay asleep for months while using almost no power. The RAK4631-R WisBlock LPWAN Module gives you that ability. It combines a powerful nRF52840 MCU with a high-gain SX1262 LoRa radio and BLE 5.0 in a 20 30 mm board. If you are tired of bulky development kits that drain batteries, this module solves the problem by delivering full-featured connectivity in a compact, low-power package. It fits into any WisBlock base board, so you can stack sensors, batteries, or GPS without redesigning your hardware. The built-in RUI3 firmware lets you send AT commands, making testing fast and painless.

RAK4631-R WisBlock LPWAN Module, nRF52840 & SX1262 w/ RUI3

Many makers struggle with unreliable long-range links and the need to support both LoRaWAN and Bluetooth in the same device. Without a dual-radio solution, you end up buying two separate modules, increasing cost and board space. The RAK4631-R solves this by offering LoRaWAN 1.0.3, LoRa P2P, and BLE 5.0 on a single chip, all managed by the easy-to-use RUI3 stack. This means you can prototype smart-city sensors, asset trackers, or environmental monitors with one compact board.
