RBLink is designed for development application for RedBear Duo using Broadcom WICED SDK, it supports debugging. You can easily attach modules from the Seeed’s Grove System to your project. If you have MFi license and the co-processor (authentication chip), you can use RBLink to develop MFi projects (e.g. HomeKit).
Redbear Blend 2 is an integrated "ARM + BLE 5.0" development board. We have integrated Nordic nRF52832 with a DAPLink chip into a single mbed and Arduino compatible board. It is targeted for makers, engineers and students to develop low power Internet-Of-Things (IoT) projects/prototypes quickly and easily.
There are two MB-N2 modules in each pack. Our new BLE Module model# MB-N2 has Nordic nRF52832 BLE chip, an on-board antenna and other components special tuning for great performance and low power consumption. The module provides all GPIO pins and supports all advance features offer by Nordic nRF52832. It is FCC, CE & Bluetooth SIG certified.
