DESCRIPTION

Overview
The Cordio BT4 Module and Customer Evaluation Base
Board is based upon the CORDIO™ BT4
Development SoC which is a low power, 40 pin 5 x5 mm QFN that contains the BT4 Radio IP plus an ARM
Cortex M0+™ host MCU.

– Cordio BT4 Module
The BT4 Development SoC in on 42 pin Module which contains the necessary discrete RF components
around the BT4 radio IP block within the SoC, the SoC’s External EEPROM and a Reset Button. The majority
of pins of the SoC are various voltage rails and I/O signals that are taken directly to the pins on the module.
This modular approach is taken to easily upgrade to future Cordio products.
The Customer Evaluation Base Board
or “Eval Board” is a platform for the Module to plug into which enables
the evaluation of BT4 Radio Hard Macro’s RF performance and the low power consumption characteristics.
Supported by a Bluetooth Smart® protocol stack from ARM®, the evaluation platform supports the choice of
either a test FW mode or an operational / demo FW mode.
Schematics and Bill of Materials for both boards can be found in the
Cordio BT4 Module and Eval board
Schematics
document included on the USB thumb drive provided in the Evaluation kit.
