D-AXE II
DEVELOPMENT
BOARD FOR THE
PICAXE
Aztec MCU Prototyping now offers the D-Axe II development
board intended primarily for use with
PICAXE microcontrollers. Engineered
in Canada and carrying their house
brand — Omega MCU Systems
(OMS) — this board builds on the
success of its predecessor and
provides a highly versatile and
modular platform from which to
develop projects based on PICAXE
eight-, 14-, and 20-pin
microcontrollers. As with all of the
OMS branded products, it is
designed to speed up the building of
prototypes and make the whole
process more reliable and repeatable.
The D-Axe II is manufactured
using SMD technology on high
quality 1.6 mm thick double-sided
FR4 fiberglass printed circuit boards
with 1 oz copper traces for long life
under hard use. All signals from the
microcontroller are brought out to
three-pin headers that include access
to the power and ground. This allows
the designer to simply plug in sensor
and actuator modules (commonly
known as ‘bricks’) to build prototypes
in a matter of minutes.
These same headers allow the D-Axe II to also be connected to
solderless breadboards, making it a
versatile development platform. It has
a 3. 5 mm stereo phone jack for
compatibility with existing AXE026
and AXE027 PICAXE programming
cables, and onboard LEDs indicators
to monitor programming and data
traffic. An onboard power regulator
capable of supplying up to 1A
ensures that it can support a large
array of modules.
For those situations where a hard
reset is required to begin a new
program load, the D-Axe II offers a
simple pushbutton solution avoiding
the traditional means of having to
remove the power
supply. A zero insertion
force socket is used to
keep chips in top shape
while reducing the
handling time. It is fully
compatible with all
current PICAXE
programming software.
While the D-Axe II
is primarily intended
for use with a PICAXE,
it also supports a
host of small PIC
microcontrollers via
a standard ICSP header.
Benefits offered by the D-Axe II
help users get to writing and finishing
code as quickly as possible by
reducing build time, and increasing
reliability and repeatability of the
prototyping process. The D-Axe II is
available for a limited time for
US$14.99.
SINGLE RELAY
BOARD
The new single relay board from Parallax can be used to turn
lights, fans, and other devices on/off
while keeping them isolated from a
microcontroller. The single relay
board allows users to control high
power devices (up to 10A) via the
onboard relay. Control of the relay is
provided via a 1 x 3 header which is
friendly to servo cables, and
convenient to connect to many
development boards. Price is
US$9.99.
PRESSURE SENSOR
MODULE
Parallax’s new SCP1000 pressure sensor module is an absolute
pressure sensor which can detect
atmospheric pressure from 30-120
