1. Introduction
This document provides guidance in setting up the Display Kit hardware, part number AMAP4PDISP,
revision 1, on the Apollo4 Plus Evaluation Board (EVB), revision 2, to get started executing memory and
display examples and measuring power consumption in various configurations. The Apollo4 Plus Display
Kit is also intended to provide an introduction to the GUI Builder.

4. Quick Start
The Apollo4 Plus Display Kit comes with the following items:
▪ Apollo4 Plus Evaluation Board (EVB), revision 2
▪ Apollo4 Plus Display Shield, revision 1
▪ USB Type C cable
▪ Four adhesive-backed rubber feet
▪ Extra jumpers
Caution: The EVB has components loaded on the back of the board. Care should be taken to not damage
these components. The included rubber feet should be applied to the bottom of the board to prevent direct
contact between the components and a desk surface.
The EVB in the Apollo4 Plus Display Kit comes with jumpers pre-configured for default operation. Also, it
has been pre-programmed with the Binary Counter example program. To begin EVB program execution,
first carefully attach the Apollo4 Plus Display Shield to the Apollo4 Plus EVB if not already attached. To do
this, press the two boards together as evenly as possible until the display shield is fully seated on the
connectors of the EVB. Then connect the USB-C cable from a USB port on a PC to the J-Link USB
connector (J6) on the EVB, and make sure the power switch (SW4) has been turned on. The LEDs on the
bottom of the EVB should begin to count up in binary, from 0 to 7.
The AmbiqSuite SDK provides many example programs that may be run on the Display Kit. To run these
examples, download the SDK via the link provided above and select any of the pre-built examples in the
SDK at /boards/apollo4p_evb_disp_shield_rev2/examples.

5. Overview of the Apollo4 Display Kit
The Apollo4 Plus Display Kit consists of two PCB assemblies:
1. The Apollo4 Plus EVB (AMAP4PEVB), revision 2 or later
2. The Apollo4 Plus Display Shield revision 1
Please note that the Apollo4 Plus Display Kit is only compatible with the (non-blue) Apollo4 Plus EVB, part
number AMAP4PEVB.
The combined features of the two-board assembly are shown in the block diagrams of Figure 2 and
Figure 3. When MSPI0 is used in hex mode (16-bit interface), MSPI1 cannot be used, as the MSPI0 upper
data lines use the same pins on the Apollo4 Plus that MSPI1 uses. An Apollo4 Plus GPIO pin, GPIO34, is
used to select between using this set of pins as MSPI1 connections or as the upper data lines of MSPI0 in
hex mode.
Figure 2 represents the two-board assembly’s feature set when connected to the APS256XXN PSRAM
device over MSPI0 in hex mode. MSPI1 is not used in this configuration.
