Apollo2 Blue EVB Quick Start Guide
1. Introduction
This document provides guidance in setting up the Apollo2 Blue Evaluation Board (EVB), revision 0.3, to
get started executing code examples, measuring power consumption in various configurations, and
beginning software development.

3. Overview of the Apollo2 Blue EVB
The Apollo2 Blue EVB features Arduino-compatible headers and an integrated J-Link debugger:
Figure 1. Apollo2 Blue EVB, Revision 0.3
The EVB has these additional features:
▪Low power reference design
▪Apollo2 Blue MCU in the LGA package (AMA2B1KK-KLR)
▪Multiple power/clock options
▪Micro USB connector for power/download/debug
▪On-board chip antenna (A1)
▪RF switch/connector (J1 - Murata MM8430-2610RA1) for BLE PHY testing without removing
chip antenna
▪Segger J-Link debugger
▪Debugger-in / debugger-out ports
▪Four user-controlled LEDs
▪Three push buttons for application use, plus a reset push button
▪Power slide switch with LED power indicator
▪Five 8-12 pin Arduino-style headers for pin/power access to shield board(s)
▪Multiple test points for power measurements
▪CE Mark and RoHS compliant
Figure 2 shows the Apollo2 Blue EVB under RF testing via the RF switch/connector.

4. Debug Interface
Figure 3 shows the Apollo2 Blue EVB set up for standard debug using the on-board J-Link debugger and
on-board power supply configured for 3.3V.

The debug interface is supported by standard J-Link drivers from Segger. Please refer to “Software
Development Tools for the Apollo2 Blue EVB” on page 11 for more details on J-Link debug support.
This EVB also supports the use of an external Cortex SWD debug interface through a standard 10-pin
debug header (DEBUG IN - J3) as shown in Figure 4.

Figure 4. Apollo2 Blue EVB’s Cortex DEBUG IN Header (J3)
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” header.
The EVB also offers the ability to be used as a J-Link debug adapter for any target board that has an
Apollo family MCU (Apollo1 or Apollo2).
Figure 5. Apollo2 Blue EVB’s DEBUG OUT Header (J4)
To utilize this functionality, use a 10-pin low-pitch standard debug connector to connect the “DEBUG
OUT” header (J4) on the EVB to the debug header on the target board. The EVB will automatically detect
when the “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 Apollo2 Blue.

Note: A voltage on pin 1 of the J4 header is required for the above mentioned automatic switch to occur.
Also, if the target VDD doesn't match the on-board voltage (either 3.3V or 1.9V), and to avoid possible
voltage level conflicts on the debug I/O port, VDDIO of the J-Link processor may need to be changed to
the target voltage by cutting SB9 and shorting SB10.
