This is the pin compatible upgrded version of the ESP-01 chip.
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
hs0038 IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 5V (although it seems to be OK down to 3.3V)To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It doesn’t do any decoding of the signal, just passes the ‘raw data’ along.
This is a power module for the standard bread boards (Small and Medium sized). It's concave design so will not wast your proto zone. It also supports both 5v and 3.3v (both can be enabled on each power rail).
We think it is a must to have on your workbench, really.
The Screw Shield extends all pins of the Arduino out to 3.5mm pitch screw terminals. It also has a lot of the utility provided by Arduino Protoshield, including: a large prototyping space of both connected and unconnected 0.1" spaced through-holes, a couple 5V and GND busses, a reset button, and a 5mm green LED.
This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for...
