SIM800L GPRS GSM Module with PCB SMA Antenna

Arduino Uno Protoshield directly fits into an Arduino UNO board and breaks out the I/O pins and makes it an expansion board. It makes it very easy to design any customer circuit. You can directly solder components on the board or connect the circuit using 170 point mini breadboard (included). The board is designed to solder both through-hole and SMD components to test them with your Arduino board. Although the SMD area is designed for 24 Pins SOIC integrated circuit and has a lot of space for TH components.

Features

• It has a standard 0.1” x 0.1” prototyping grid with big pads
• Comes with both stacking and plain header, choose whichever you want while soldering together
• An IC pattern for adding a DIP IC up to 20 pins
• Power rails down the middle and side
• A reset button and an extra use button
• 2 3mm general use LEDs, red and green, as well as 2 matching resistors
• A pass-thru ICSP stacking header so you can stack any kind of the shield on top, and/or use and AVR programmer
• A surface-mount chip area for up to 14 SOIC size part
• Compatible with tiny breadboards
• Every pin is brought out
• Gold plated pads
• 2 x 0.1uF ceramic capacitors on either side for extra power stability
