Page 5: Introduction
Ultra-Low Power Apollo MCU Family Introduction This document provides guidance in setting up the Apollo3 Blue Plus Evaluation Board (EVB), part number AMA3B2EVB, revision 1.0, to get started executing code examples, measuring power consumption in various configurations, and beginning software development. -
Page 6: Overview Of The Apollo3 Blue Plus Evb
Ultra-Low Power Apollo MCU Family Overview of the Apollo3 Blue Plus EVB The Apollo3 Blue Plus EVB features Arduino-compatible headers and an integrated J-Link debugger: Figure 1. Apollo3 Blue Plus EVB, Revision 1.0 Figure 2. Apollo3 Blue Plus EVB Parts Location... - Page 7 Customer InfoSpace, referred to as INFO0. Initial provisioning of the part would include programming a valid INFO0 and programming the main firmware image in the flash. The Apollo3 Blue Plus EVB is shipped with the INFO0 configuration preprogrammed with optimal settings for the EVB layout.

Page 8: Debug Interface
This EVB also supports the use of an external Cortex SWD debug interface through a standard 10-pin debug header (DEBUG IN - J1) as shown in Figure 3. Figure 3. Apollo3 Blue Plus EVB’s Cortex DEBUG IN Header (J1) No jumper changes are required to use an external debug adapter. Simply connect the external debug adapter with a 10-pin ribbon cable connector to the “DEBUG IN”... -

“DEBUG OUT” header is connected to another target board and reconfigure the integrated J-Link to connect to this external board rather than the on-board Apollo3 Blue Plus. Note: A voltage on pin 1 of the J2 header is required for the above mentioned automatic switch to occur. -
Page 10: Software Development Tools
Ultra-Low Power Apollo MCU Family Software Development Tools The standard Segger J-Link debug interface is used on the Apollo3 Blue Plus EVB. Please install the latest Segger J-Link software, and configure your preferred development IDE (Keil, IAR, or Eclipse) to use J-Link debug interface. -

Apollo3 Blue Plus EVB Quick Start Guide Ultra-Low Power Apollo MCU Family Power Supply Options and Measuring Current There are three power supply options for the Apollo3 Blue PlusEVB: ▪ Operate at 3.3V as provided by the on-board power supply ▪... -
Page 12: Header P19 Configured For 3.3V Operation - No Current Measurement
Apollo3 Blue Plus EVB Quick Start Guide Ultra-Low Power Apollo MCU Family As an example for setting the jumpers on P19, Figure 7 shows the EVB configured for 3.3V operation with jumper across VDD_PS and VDD_MCU for no current measurement. - Page 13 Apollo3 Blue Plus EVB Quick Start Guide Ultra-Low Power Apollo MCU Family cut to make U8 (VDD_PS_LDO generator) output 1.9V instead of 1.8V in the low-voltage configuration. This will enable current consumption measuring using equipment with a sensing resistor, such as a digital multimeter.
