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.

Adapter
Figure 3. Apollo2 Blue EVB using On-board J-Link Debugger
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.

Apollo2 Blue EVB Quick Start Guide
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.

5. Software Development Tools for the Apollo2 Blue EVB
The standard Segger J-Link debug interface is used on the Apollo2 Blue EVB. Please install the latest Beta
Segger J-Link software, and configure your preferred development IDE (Keil, IAR, or Eclipse) to use J-
Link debug interface.
Links to development tools that support Apollo2 Blue:
▪ SEGGER J-Link Software (6.14 or newer) : https://www.segger.co /downloads/jlink
▪KEIL uVision (MDK523 or newer): https://www.keil.com/demo/eval/arm.htm
▪New Keil Pack (Also used by Eclipse): http://www.keil.com/dd2/pack/#/third-party-download-dialog
▪IAR Version 7.80.4 (8.10.1 or newer): https://www.iar.com/iar-embedded-workbench/tools-for-
arm/arm-cortex-m-edition/
▪Atollic TrueSTUDIO (7.1.2 or newer): https://www.atollic.com/truestudio/
▪GCC 5.3.1: https://gcc.gnu.org
Regardless of preferred IDE, please install the Segger J-Link software. All of the above development
environments support J-Link, but you must have the latest J-Link software installed. Most alternate
development environments also are supported by J-Link.
Please refer to the AmbiqSuite Getting Started Guide (AMSDKGS) at http://ambiqmicro.com/apollo-ultra-
low-power-mcu/ for more details on setting up development IDEs to use J-Link.

6. Power Supply Options and Measuring Current
There are three power supply options for the Apollo2 Blue EVB:
▪Operate at 3.3V as provided by the on-board power supply
▪Operate at 1.9V as provided by the on-board power supply
▪Provide externally supplied power
Figure 6 shows header P19 which is used to select a power configuration through jumper installations, as
well as the option to measure the supply current to the MCU with an ammeter. Solder bridge SB4 can be
filled instead of jumpering from pin 1 to pin 2 if current measuring is of no interest.
SB4
_1.9V
Figure 6. Voltage Selection on Header P19
Table 2 shows valid jumper configurations for P19. All other configurations are invalid. Note that a jumper
across pins 7 and 8 is not necessary and does not do anything - the pins are available only for easy
access to ground.

a. Note that the Apollo2 Blue EVB supports only Step Down operation for the BLE, and therefore does not
sup-port the full voltage range of the device.
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.

Figure 8 shows the EVB configured for 3.3V operation with current measuring leads across VDD_PS and
VDD_MCU for current measurement.
