8-channel Solid
State Relay board
My latest design! Outputs are
controlled by silent, non-mechanical Infineon PVT212 "relays", utilizing
"International Rectifier’s proprietary HEXFET
power MOSFET as the output switch" wired up for
0.25 ohm output resistance to control
up to 150V AC/DC and up to 825mA loads.
Or, lower capability (and cost) PVT312 with 3 ohm output resistance for
390mA current switching can be used. Outputs controlled by sending
data to a '595 shift register, and indicator lights show the
active channel(s). Available with male headers, female headers, or
screw terminals. Inputs are daisychained to a second set of contacts
for easy daisychaining.
Contact me for pricing, PVT212 vs
PVT312 and female vs screw terminals make a big difference. USPS
mailing and paypal fee added to all totals.

32
channel N-MOSFET board. Designed
for 32 1A loads.
The
thru hole transistors
went obsolete, so the board has been converted to all SMD except for
the 74HC595s and the screw terminals. Also added 2A 1206 size diodes
from the MOSFET Drain to the supply, it might be enough to eliminate
the need for a diode across a low current coil, like a relay, solenoid,
or small motor.
Easy
to use - just shift in 4 bytes, a 1 turns an output on to sink current.
OE/ allows for PWM of all parts together. Easy to daisychain with In
and Out headers.
Available
completely
assembled, $105 plus mailing cost and paypal fee, or
Kit -

New
"mini" card types, Mini 2560 & Mini 2561!
We're
assembling 2560 cards now, all IO pins broken out. Just add power, or
connect a USB Serial adapter
(FTDI Basic clone shown) and you're on your way. Shipped with headers
shown; add IO headers
as you see fit, or contact us for other options. ICSP Header, DTR
enable jumper, FTDI header with 5V enable jumper.
$46 plus shipping & paypal fee.
Mini
2561 will be posted soon, we're waiting on stencil delivery to put one
together.
Standalone
Programmer!
Ever
needed to program some cards in the field but didn't have access to a
laptop? Now you don't need one! We collaborated with Nick Gammon and
turned his "Upload Hexfile from SD card" into a full-fledged standalone
programmer. Connect up a power source (3xAA battery pack, 5VDC
wallwart, 7-12VDC wallwart or non-running vehicle power), dial in the
program to download and press the Start
button. More details on this
page for file naming and
re-setting up the card if needed.
Two

programmer supporting up to 256 files, $50. Contact us
to order
one. All boards include a Sandisk 4GB SD card and 6 inch/15cm
programming cable. Shipping & paypal fee added to all orders.

Mega
Screw Shield.
96
screw
terminals to let you securely connect your signals and your shields.
Fits all Mega board variants: Mega, MegaADK, Due, Ethermega, Etherdue.
Two pairs of 3.3V/Gnd and six pairs of 5V/Gnd terminals.
Board
lengthened at the power
connector end for additional screw down holes. Hole
added
to access the Due Erase button. Jumpers added to allow separation
of D51-52-53 from the ICSP header. Board size is 130x77mm,
overlapping the Mega board edges.
All
Screw Shields use Phoenix Contact
brand screw terminals, Made in Germany, and very high quality.
$37
each kit. $52 for assembled boards. Shipping and paypal fee
added
to all orders.

paypal fee additional. Worldwide shipping available.
Uno Screw Shield. Updated
for 2016
The
board is a little bigger in length now, 77mm across by 73mm, has each
header pins brought out to a 3.5mm pitch
screw terminal, and to a pin in the 12x20 protoboard area. Extra
3.3V/Gnd screw terminal added along with 4 more 5V/Gnd screw terminals.
The ICSP
header will support ICSP connectors from other shields.
Kits
are $16.50
each, and ship in a padded envelope. Assembled cards are $21.50 and
