Introduction
Zilog’s Wireless Zdots®Single Board Computer (SBC) Development Kit provides a gen-
eral-purpose platform to evaluate the capabilities and operation of Zilog’s eZ80F91 micro-
controller unit (MCU) and the Realtek 8711 Wireless Transceiver. The eZ80F91 is a
member of eZ80AcclaimPlus!™product family, which offers on-chip Flash capability.
The Wireless Zdots SBC Development Kit features two primary boards— the
eZ80AcclaimPlus! Wireless Zdots SBC and a base board. The Wireless Zdots SBC Devel-
opment Kit provides a full development platform when using both the boards. It can also
provide a smaller-sized reference platform with the Wireless Zdots SBC as a stand-alone
development tool.

Wireless Zdots®SBC Development Kit
Overview
The Wireless Zdots SBC Development Kit provides a set of tools to evaluate the features
of eZ80F91 MCU and the Realtek 8711 Wireless transceiver to develop a new application
before building the application hardware. The eZ80AcclaimPlus!™Wireless Zdots SBC
Development Kit, together with its plugged-in Wireless Zdots SBC, can operate in stand-
alone mode with Flash Memory, or interface via USB Smart Cable (or any Zilog®debug
tool) to a host PC running ZDS II Integrated Development Environment (IDE) software. A
block diagram of the eZ80AcclaimPlus! Wireless Zdots SBC Development Kit and the
Wireless Zdots SBC is displayed in Figure 1.

Mounting the Wireless Zdots®SBC to the Base Board
The Wireless Zdots SBC features two 30-pin connectors. However, only connector labeled
J1 is installed on the Wireless Zdots SBC. When mounting the Wireless Zdots SBC onto
the base board, check its orientation to the platform to ensure a correct fit. Observe that the
30 pins of the Wireless Zdots SBC plug into connector J1 on the base board. The compo-
nents on the Wireless Zdots SBC should point into the components of the base board. See
Figure 2 on page 3.
Changing the Power Supply Plug
The universal 5 V DC power supply offers three different plug configurations and a tool
that aids in removing one plug configuration to insert another, as displayed in Figure 7.
Figure 7. Universal 5 V DC Power Supply Plug
Follow the steps below to exchange one plug configuration for another:
1. Place the tip of the removal tool into the round hole at the top of the current plug con-
figuration.
2. Press down to disengage the keeper tab and push the plug configuration out of its slot.
3. Select the plug configuration appropriate for your location, and insert it into the slot
formerly occupied by the previous plug configuration.
4. Push the new plug configuration down until it snaps into place, as displayed in
Figure 8 on page 8.
