Quad-Core Arduino? No, it is Geekduino MEGA Olympic! The Mega Oliymic has 4 UNO R3 interfaces, each unit has one UART, 2 I2Cs and 4 analog inputs. Two of the 4 units have the same SPI interface(Unit 1 and Unit 3), and the other two units have the same ICSP of ATmega2560 , so the Mega Oliymic not only [...]
Geekduino Mega Olympic board based on the ATmega2560.It has almost all the elements of Arduino Mega 2560 R3, but it is more.Please stay close with us to explore the new elements on our one and only London Olympics edition!
Makerbot Reprap mk7+gen4 (Improved Version) Description (By Makerbot Official) This extruder was designed from scratch, and contains a number of custom manufactured parts. We’ve learned a lot over our past extruder designs, and incorporated a lot of those lessons here: that’s why it’s smaller, lighter, and faster to build. And since it’s designed from [...]
For the vacation of china (02-04-12 – 05-04-12), We are sorry about the GPS Shield would be manufactured latter. Now we design another Shield for Arduino, there will manufactured together with GPS Shield, after the date “15-04-12″.
Hi Guys, We will introduce our new product to you — Arduino Bluetooth Shield V1.0.
Arduino Bluetooth Shield will be powerful and easy to use.
Please visit our wiki (Arduino Bluetooth shield V1.0 ) to learn more information.
Arduino WIFI shield will be made in next month.
It will be easy to use because it suppor “AT” command!
Do you like it?
There new product will available soon.
All of our shield/bee will be manufactured in accordance with the single row stark.
Yes, our design work has been launched, the open source hardware (including GPRS shield/WIFI shiled/Bluetooth shield) will meet with you in October .
