UG569: Adapter Board for Co-Processor
Radio Boards User's Guide
The Adapter Board for Co-Processor Radio Boards is an excel-
lent way to explore and evaluate Co-Processor Radio Boards
with various host devices using either SPI or SDIO interfaces. Ex-
ample of host devices are EFM32 or EFR32 devices, Raspberry
Pi or other Linux machines with a SDcard interface, STM micro-
controllers.
When connected to a compatible host board, the Adapter Board puts the Wi-Fi Network
or Radio Co-Processor (NCP/RCP) board in direct comnunication with the host device,
securing correct operation while debugging.
The kit comes in three different variants as BRD8045A, BRD8045B and BRD8045C
which easily integrate and bring additional wireless connectivity to respectively compat-
ible Silicon Labs Wireless Pro Kit Mainboards through the EXP header, a Raspberry Pi
through the HAT interface, and other host boards equipped with an Arduino UNO rev 3
compatible host interface, for example STM32 Nucleo-64 boards.

UG569: Adapter Board for Co-Processor Radio Boards User's Guide Power Supply 5. Power Supply This section covers two important aspects connected to power supply: how to power the Adapter Board and how to power the Co-Pro- cessor Radio Boards attached to the Adapter Board. 5.1 Board Power Options The Adapter Board needs a 5V power source to operate correctly. -
Page 23: Device Power Options
UG569: Adapter Board for Co-Processor Radio Boards User's Guide Power Supply 5.2 Device Power Options When correctly powered, the Adapter Board interfaces a Host and a Device on differents boards and it ensures that the two portions of circuit in communication always operate at the same voltage level. This is important to avoid back-feeding one of the two circuits and to perform correct current measurements. -
Page 24: Current Measurements
UG569: Adapter Board for Co-Processor Radio Boards User's Guide Current Measurements 6. Current Measurements Measuring current consumption of a Co-processor is in general a more complex task than measuring the consumption of a Microcon- troller. While a Microcontroller can be programmed for test purposes, to enter a determinate state (e.g. sleep state) at start up, a Co- processor typically needs a Host that sends specific instructions to operate and enter a determinate state, which one might want to investigate. -
