This is a breakout board for the Maxim MAX7456 monochrome on-screen
display chip. The board is set up with all supporting circuitry and RCA
connectors to allow the user to easily interrupt and overlay text and/or
graphics onto a video signal (PAL or NTSC). Just plug in your video
signal to "Video In", plug your TV into "Video Out", connect a
microcontroller to the SPI interface and supply the board with 5V@100mA
(worst case) and you're good to go. Supplied sample code runs on an
ATMega168/328 (16MHz) and compiles with WinAVR, so it's just about
"plug-and-play" with an Arduino board.
Features:
-
Input voltage 5V
-
Current consumption 100mA, worst case
-
5V SPI interface

Hot on the heels of our standard Raspberry Pi GPIO Breakout Board, we have the Pro version. In the same form factor we have added a 500mA 3.3V voltage regulator to power all of your sensors and devices. The Raspberry Pi uses quite a lot of the onboard regulator's power
output leaving very little for anything you may want to connect up that
requires a 3.3V supply. So now you have 500mA at your disposal without
affecting the Raspberry Pi's power.
Supplied in kit form, it includes the following
-
GPIO Breakout Board PCB with all surface mount components already soldered on
-
2 x 13 way header pins
-
26 way IDC box header.
Soldering is required to assemble the kit.

Ok, this one may not be everyone's cup of tea, but if you want a cheap
Arduino Ethernet shield, then this is definately for you. It comes as a
kit of parts and so is also a great kit for practising your soldering
skills on. All components are through hole so all you need is a
soldering iron and solder. Building is straightforward and doesn't
really need any instructions as all the part locations are clearly
labeled on the board. However, instructions are available in the links
at the bottom of the page.
The Arduino communicates with the Ethernet Shield using the SPI bus.
This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and
52 on the Mega. An on board jumper allows use of Digital Pin 10 for chip
select, or a handy wire pad can link to any other pin for chip select.
The Ethernet shield uses the Arduino EtherCard library
which comes with many example programs. This library assumes (in the
example programs) that pin 8 is being used for chip select, so if you
are using the default pin 10 on this board, you need to initialise the
card using the extra pin parameter...ether.begin(sizeof
Ethernet::buffer, mymac, 10)
Supplied with header pins (not stackable headers) for connection to
Arduino, but stackable headers can be used instead, just beware of upper
shields conflicting with the RJ45 socket.
Features
-
ENC26J60 based Ethernet
-
Jumper select for 5v or 3v3 operation
-
Includes all components needed.

This is our own version of Sparkfun's Openlog Data Logger. We wanted a
slightly different design so we have made our own, whilst still being
100% software compatable. We even offer it with the Openlog software
pre-installed our our own Arduino Data Logging Software.
This is the new Version 2 board which retains the same form factor of
the previous board but breaks out an additional 3 pins from the
ATmega328 chip. These additional pins allow the connection of analog and
digital sensors and other devices to make an ideal standalone data
logging board.
The serial and power connections match with the Sparkfun FTDI basic board, so now you can plug it straight in to program it.
Each unit is fully tested
Features
-
ATmega328 running at 16MHz / 3.3V
-
Quality Molex microSD socket for long lasting connections
-
100% compatable with Sparkfun Openlog software
-
4x mounting holes (2mm diameter)
-
Two LEDs indicate status
-
Input voltage from 3.3V to 6V
-
Ardulog runs at 3.3V but all pins are 5V tolerant
-
Reprogrammable ATmega328 using the Arduino IDE.
-
Arduino UNO Bootloader installed
-
Datalogging Sensor input connections
-
Up to 4 Analog Input pins for logging analog signals (Arduino pins A1, A3, A4, A5)
-
I2C pins SDA and SCL (on analog pins A4, A5)
-
SPI
-
RX/TX Serial

This 6-pin connector and plug set is great when you need to create a
robust connection for signal or power. This product consists of two
separate parts, the panel-mount jack and the mating plug. The plug has a
ring which screws to the panel-mount connector ensuring a solid
connection that won't pull off.
The connector uses 6 solder-cup connections for easy wiring. The
panel-mount side mounts in a 15.5mm hole with the aid of a lock-washer
and nut (both included). The jack uses solder-cup terminals as well and
comes apart for easy assembly. It even has a strain relief clamp on the
end which clamps down to 5mm for a sturdy connection. Pins are clearly
labeled on both jack and connector.

This graphical display looks fantastic, at a great price! This display
will add the ultimate cool to your project, with a black negative
display that has a full RGB LED backlight. You can control with PWM to
make any color you can imagine, and it will look stunning with the black
inverted (negative) background.
Four mounting holes and a blank 11 pin 2mm-pitch labeled breakout on
the side - we just soldered some wire to each hole as shown in the
photos, its very easy. (The LCDs have no wires soldered in when we ship
them)
Bonus! We're including a free 4050 level shifter chip so that you can safely use it with your favorite 5V microcontroller
Features
-
Serial interface uses only 4 or 5 digital pins
-

The RFID USB Reader is a simple to use, USB to serial base unit for the
ID-2, ID-12, and ID-20 readers. Simply plug a reader into the headers
and attach a miniUSB cable. Open a terminal program of your choice at
9600bps 8N1, then scan your 125kHz ID tag and the unique 32-bit ID will
be shown on the screen. The unit is based on a FTDI chip and comes with a
read LED and buzzer.
This new revision uses SMD headers for the RFID module, and has a
solder jumper which allows you to disable or enable the buzzer.
Note: This product does not come with the RFID reader. Check Related Products for compatible readers.
Dimensions: 1.4x1.2x0.57"
