Microduino-Core is an 8-bit microcontroller development board, with the core of Atmel ATmega328P and ATmega168PA series. It is an open-source, compatible-with-Arduino UNO controller module. Compared with Arduino UNO, Microduino-core has the following features:

It uses the U-shape 27pin Microduino interface specification, and it has multiple interface compatible peripheral modules and sensors.
Microduino breaks up the USB serial interface communication module and Atmega core module, and makes them into two Microduino development boards which can be divided and stacked.
It uses micro USB to supply power, and removes the external power supply socket, making the whole size very small, 25.4mm long X 27.94mm wide (the size of a 1 quarter coin).

Lightweight design makes Microduino has a unique advantage in the project designs with the requirement of size and cost, and it can achieve the fast and flexible function extension for the design with other Microduino modules, according to the need of the players.
Microduino uses java and C language development environment, same as Arduino. The players can use Arduino IDE, together with software such as Flash and Processing, use Microduino and other electronic components, modules, and sensors to make many interesting and interactive works.



Q:How do I judge that the voltage of the Core+ is 3.3V or 5V?

A:Look at the resistor. If the R1 is welded, it is 3.3V. And if the R2 is welded, it is 5V.

Q:Can I use 3.3V voltage to supply power to the Core+ of 16m clock frequency?

A:It is not recommended . If the voltage is too low, it is easy to be unstable.

Q:Can I use 5V voltage to supply power to the Core+ of 8M clock frequency?

A:Yes, you can.



Small, cheap and stackable.
Open-source hardware circuit design, and programming development environment compatible with Arduino;
Same as Arduino, Microduino can use ISP download line to program to「bootloader」 flexibly;
Unified Microduino interface specification and abundant peripheral modules, can be quickly and conveniently and flexibly connected and extended with other modules and sensors conforming to the Microduino interface specification;
2.54-distance parent interface is convenient to integrate into the hole plate.
