Editorial narrative

The RAK11722 WisBlock Core module is based on the powerful AMA3B1KK-KBR-B0 MCU from Ambiq (aka Ambiq Apollo3) together with a Semtech SX1262 LoRa® transceiver. Together with the WisBlock Base Boards, WisBlock Sensor and IO modules it is a perfect start to build compact, low-power IoT devices without the need to design custom PCB’s. The AMA3B1KK-KBR-B0 has an integrated Bluetooth Low Energy transceiver that enhances communication capabilities. The RAK11722 WisBlock Core module works with all of our WisBlock Base Boards and can be extended with sensors or interfaces from our large WisBlock module collection. The RAK11722 WisBlock Core module has an onboard BLE chip antenna and a MHF connector for the LoRa antenna. The two RF communication characteristics of the module (Lora® + BLE) makes it suitable for a variety of applications in the IoT field, such as home automation, sensor networks, building automation, and IoT network applications. The RAK11722 comes with our RUI3 based AT command firmware that is fully compatible with the RAK3172 and RAK4631-R. With the RUI3 API it is easy to integrate our WisBlock sensor and IO modules into your custom IoT firmware.
