Specification ATmega328 microcontroller Input voltage - 7-12V 14 Digital I/O Pins (6 PWM outputs) 6 Analog Inputs 32k Flash Memory 16Mhz Clock Speed Projects Project 1. In addition, there are two new pins placed near the RESET pin. The 3.3V max current consumption must limit within 600mA.Īgain, the 3.3V LDO is serial to 5V regulator, to calculated 5V power consumption, must consider the 3.3V current consumption. The Arduino Uno R3 also adds SDA and SCL pins next to the AREF. In MassDuino UNO LC’s design, the Pcm must limit within 3.5W, so if the Input voltage is 9V, the voltage difference is 9V-5V = 4V ,to limit Pcm within 3.5W ,the current consumption must limit within 3.5V/4V = 0.875A. Arduino projects can be standalone or can communicate with software running on computers (for example: Flash, Processing, Max/MSP). The 5V Current limit is depended on the voltage difference between input and output, the regulator power consumption can be calculated below: Microcontroller: ATmega328 (datasheet) Operating Voltage: 5V Input. Massduino UNO LC is an Arduino compatible board, It’s based on Arduino UNO R3 design, So you can use MassDuino UNO LC as Arduino UNO, All Code, shield and IDE for Arduino UNO R3 are also valid on MassDuino UNO LC, Some visible improvement on hardware make MassDuino more flexible and easier use, For example: 3.3V or 5V IO selectable allow you connect some 3.3V modules (such as XBee) to Massduino directly.ĭigital I/O Pins 14 (of which 6 provide PWM output) This board is a generic variant, built from the open source Arduino Uno R3 design. =*/Ĭhip level support (MD-328D IC Lower to 0.6USD for mass purchase,click to view)Įasy for prototype development, directly use for mass production!ġ0 pcs MassDuino LC Lite = $19.99 (Click to View) = USD 1. *=ĪnalogRead() // 10bit ADC, Compatible to UNO R3ĪnalogRead_12bits() // 12bit ADC, 130 spsĪnalogRead_16bits() // 16bit ADC, 125 sps
