Although the Arduino is already a very compact and small-sized microcontroller, but you still wish it to become even trimmer or slimmer?

Oh well, you wish is granted today, as there is a new trimmer/slimmer standalone prototype board, which specially designed for the Arduino/ATMEGA8 and its named “Protoduino”.

Or, you want to take your Arduino project that you wish to take one step over the temporary breadboard, but you’re too lazy to create a new PCB, then this Protoduino might help you solve up the hassle.

This Protoduino board is well designed for the easy customization, which the trace can be cut for giving an additional flexibility. Beside that, you can also trim away those unwanted parts of the board, as you want.

Some of the great features for this Protoduino are:

1. The input voltage (Vin): 7.5-9VDC
2. The On-board power supply output: 5 VDC at 100mA max
3. Clock speed: 16 MHz
4. Resistor network: 150 ohm, 100mW max per element

As this is a kit, you still need to do some basic soldering to assemble it. In addition, you cannot program the ATMEGA chip on this board, as there is no any USB controller here. Also, be careful about the 7805 regulator, which it can get extremely hot and apply a heatsink on it for your own safety.
