SAME GREAT FEATURES. SMALLER OPTIMIZED PACKAGE.
The newest addition to our microcontroller product line is a POTENT POWER HOUSE! We call it the Ruggeduino MINI SMALLS but there is nothing Mini about the feature set. Engineered around the AVR® ATmega Microcontroller IC with 8-Bit 20MHz 32KB operation, this is essentially a Ruggeduino-SE in miniature. Take note this is more than just a Mini. It's a MINI SMALLS.
Some of our customers asked for a smaller sized version of our very popular Ruggeduino to allow them to squeeze all of the great features and reliability of a Ruggeduino into their compact design. We listened. The design has been carefully engineered to offer huge performance in a very compact yet efficient footprint. The small size also packs a more powerful punch than standard Mini boards. Here is the reason- standard Arduino Minis have a linear power supply which are not intended to be taxed. When the current goes up the amount of heat produced increases drastically. We have designed the Ruggeduino MINI SMALLS with a Switching Power Supply which is much more efficient and generates less heat and therefore capable of sourcing more current. The PCB has also been carefully designed to dissipate heat better than a standard Mini which has a very small thermal mass to dissipate heat. Overheating leads and Ruggeduino MINI SMALLS was designed to be keep its cool. The result is the Ruggeduino MINI SMALLS can do things a Mini simply can not. Best of all the Ruggeduino MINI SMALLS is priced right between our Ruggeduino-SE and Ruggeduino-ET microcontroller boards.
Operating voltage thresholds have also been increased to 28V to allow integration with 24V systems. Again, standard Minis can not operate at this level.
We have taken what we have learned from the Ruggeduino-SE and rolled it into this great package measuring 1.4" X 2.16"
Rugged Circuits protection
Efficient power supply
Increased operating voltage range
Increased GPIO functionality and voltage thresholds
Flexible header connectivity
AVR AVR® ATmega Microcontroller IC 8-Bit 20MHz 32KB (16K x 16) FLASH 32-VQFN (5x5)
4.5V-28V Input Voltage
500 mA VUSB Protection

2X6 Programming Header
VIN Overvoltage TVS
Mounting Hole Diameter 3.5MM
200mA VIN PTC
Microcontroller Total Current Limiting
PTC and Zener Protection up to 24V on D0-D5 and A0-A5
The input thresholds for the microcontroller pins:
Guaranteed high at 0.7*VCC
Guaranteed low at 0.3*VCC
The microcontroller runs at VIN or VCC minus 0.3V with an upper limit of 5V. If running off USB, that puts the thresholds at approximately (5-0.3)*0.7 = 3.29V, and (5-0.3)*0.3=1.41V
The microcontroller pins are rated to source an ABSOLUTE maximum of 40mA. The PTCs on the protected pins will trip in the ~30mA range and start limiting current.
Operating Temperature -10C to +85C
Standardized Unprotected Pins D6-D13. Populated with zero resistors and no diode for increased flexibility if protection is not required. Please note that pins D6-D13 can be upgraded to "protected" status. Contact us for more details.
Header outputs are on 0.100" Pitch. Headers or pins are not included allowing users to custom tailor the board to their needs. Connectivity options include: Bare, Pin Headers, Standard Headers, Stacking Headers, and Screw Terminals.
