Hardware and Setup#

This page describes the supported Silicon Labs boards, reference hardware for Aliro reader development, and how to install the Aliro extension in Simplicity Studio 6.

Supported Boards#

Aliro example projects target EFR32MG24 and EFR32MG26 Series 2 wireless MCUs. The Aliro extension templates are compatible with the development boards listed in this section. To build for a board that is not listed here, create the project in Simplicity Studio and select your target board during project configuration.

Note: BRD4187C on the Wireless Starter Kit (WSTK) is the primary reference board used in the Getting Started demos and pin-map examples on this page.

Reference Kit (Demos)#

The Getting Started walkthroughs use BRD4187C on a WSTK mainboard (BRD4002):

• EFR32xG24 Pro Kit (BRD4187C)

Reader Hardware#

ST Near Field Communication (NFC) Evaluation Boards#

The NFC-based examples and demos are designed to work with the ST Nucleo NFC boards from STMicroelectronics and a Silicon Labs custom-built header adapter for these boards. An example project can be modified to work with other NFC hardware.

Connect one of these boards through the expansion (EXP) header adapter:

X-NUCLEO-NFC10A1 (ST25R200):

X-NUCLEO-NFC12A1 (ST25R300):

Aliro Minimal Reader and AliroMatterLock NFC projects include the st25r200 component by default. Switch to st25r300 if your hardware uses ST25R300.

Expansion (EXP) Header Adapter#

A custom adapter connects the ST Nucleo NFC board to the Silicon Labs expansion port. Contact the Sales team to obtain the adapter.

Assembled Reader#

Serial Peripheral Interface (SPI) Pin Map (EFR32MG24 ↔ ST25R)#

The following pin map applies to the BRD4187C MG24 reference board. Verify pin assignments when using a different supported board.

Optional Liquid Crystal Display (LCD) and NFC Pin Reroute#

If the expansion (EXP) adapter routes pins that conflict with the WSTK LCD, reroute as shown:
