Here’s a handy Arduino shield we’ve had a lot of people looking for a dedicated and well-designed data logging shield. We worked hard to engineer an inexpensive but well-rounded design. Not only is it easy to assemble and customize. The Data Logger module Logging Shield data Recorder Shield also comes with great documentation and libraries.

SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card. It also equips a Real-time clock (RTC) which keeps the time going even when the Arduino is unplugged. And, the most important the battery backup lasts for years. Cool

Included libraries and example code for both SD and RTC mean you can get going quickly Prototyping area for soldering connectors, circuitry or sensors. The Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run.

The SYB-170 Mini Solderless Breadboard is named for its 170 tie points. It has 17 columns of 10 holes, which are separated into two pairs by a central notch, and labelled 1 to 17. Each column is also labelled, with a letter from A to J to that they can be easily referenced in instructions ( like the squares on a chessboard ).

It has a peel and sticks adhesive backing as well as two mounting holes for M2 screws so you can anchor it down.

This solderless, re-usable breadboard is made from sturdy ABS plastic housing. Great for prototyping, testing and creating add-on modules or new circuits. It standard nickel plated spring clips ensure longevity and firm grip. As a single unit, the PTBB-170W provides one large (170) tie-point IC circuit terminal strip.  If you run out of space, the PTBB-400W can be pair with additional breadboards (below) to accommodate larger projects. Works with LEDs, transistors, diodes, capacitors, and resistors.

A GL-12 840 Points Solderless Breadboard is an invaluable tool for experimenting with circuit designs whether in the R&D or university lab. A breadboard is used to make up temporary circuits for testing or to try out an idea. No soldering is required so it is easy to change connections and replace components.

Parts will not be damaged so they will be available for re-use afterward. 840 Tie points – 128 Groups of 5 connected terminals, 8 Bus of 25 connected terminals Reusable for fast build a prototype of an electronic circuit – will accept transistors, diodes, LEDs, resistors, capacitors and virtually all types of components – No soldering required – Can modify or revise the circuits easily Fit for jumper wire of 0.8mm diameter – Standard 2.54mm hole spacing Adhesive sheet on the back side of the board – Multiple breadboards can be spliced together too.
