This PCB allows you to mount and add your own custom circuity to your Arduino ATmega2560 controller board. You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard (not included) to quickly test circuit ideas without having to solder. It's got extra connections for all of the Arduino Mega I/O pins, and it's got space to mount through-hole and surface mount integrated circuits. It's a convenient way to make your custom Arduino circuit into a single module.
This Arduino Proto Shield mounts on top of the Arduino Mega ATmega2560 controller board. It does not fit on the Arduino Duemilanove/Uno (ATmega328) board.
Mega Proto Shield Footprints
- 1.0 Arduino pinout
- Reset button
- ICSP connector
- 14-pin SMD footprint (50 mils pitch)
- 32 double-row through-hole pads; standard Arduino breakout layout
- Proto area with multiple THT pads; 100 mils pitch
The product offered on this page is the printed circuit board (PCB) only. It does not come with any connectors or components (e.g. no reset button or ICSP connector — just spaces to install them).
The Proto Shield brings power from the Arduino standard 5V and GND pins to the two power bus rows placed between the through-hole package footprint, which can be used for powering DIP sockets or for power and ground rows.
On the ICSP connector, only 5V, GND and RST are wired to the respective pins on the header. MOSI and MISO are present only on the connector pads.
The maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. The screw holes allow the shield to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins. This is a standard Arduino quirk.
