Builds on the
original Bobuino, makes USB/Serial easier to assemble, adds lots of
connection options besides just shields - signal/power/ground available
at each pin location. Here it is fully decked with screw terminals and
onboard FTDI Module, and with no screw terminals and an offboarrd FTDI
module. SD card with 74HC4050 SPI buffering, MAX3232 for RS232 on
Serial 2, battery bacled DS1307 with 32.786 KHz crystal.

Uno Screw Shield.
was asked a couple of times if there was an Uno version of the Mega
Screw Shield. So I finally made one up. It looked kind of empty, so I
added a prototyping area.
are some pics of the shield on an Uno and on a Mega.
board is 67mmx77mm, has each header pins brought out to a 3.5mm pitch
screw terminal, and to a pin in the 12x20 protoboard area, and the ICSP
header will support ICSP connectors from other shields.
bought 10 PCBs to try them out - I can send them out as kits for $14.50
each, in a padded envelope will be maybe $3 for shipping, or flat rate
boxes for $5.35. Foreign shipping in padded envelope around $8.
Assembled boards, add $5, will be shipped in flat rate boxes only.

Uses SPI to very quickly send 12 bytes to the Open Drain shift
registers, rated for 150mA continuous, up to 50V. Tested with LED
strings powered from 5V, string anodes connected to +12V.
