  1. As our customers are starting mass-production and deploying their products globally, we want to clarify that our modules hardware is supporting multiple LoRaWAN regions. As there is no difference in the hardware, we optimized the variants in our store to make it easier to select the correct module. Please note that the difference between the variants is only in the label on the module to reflect the different regional telecommunication certifications.

Product Description

The RAK11721 breakout board is based on the powerful AMA3B1KK-KBR-B0 MCU from Ambiq (aka Ambiq Apollo3) together with a Semtech SX1262 LoRa® transceiver. It is a perfect start to evaluate the RAK11720 stamp module

The AMA3B1KK-KBR-B0 has an integrated Bluetooth Low Energy transceiver that enhances the communication capabilities.

The RAK11721 breakout board offers pin headers to access the pins of the RAK11720 stamp module with jumper wires. The breakout board includes as well a chip antenna for BLE and a SMA connector for a LoRa® antenna.

The two RF communication characteristic 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 RAK11720 comes with our RUI3 based AT command firmware that is fully compatible with the RAK3172 and RAK4631-R. In addition, you can create your own custom firmware with the RUI3 API..Please select a variant for your LoRaWAN® region according to this table:
