Microduino - what if everything is taken and divided?
Arduino is a very popular, versatile and fairly budget platform, but sometimes its functionality is somewhat redundant, or vice versa, something is sorely lacking. And here comes to the aid of Microduino - this is an Arduino-compatible platform, consisting of a kernel and a variety of additional modules, characterized by compactness and low price.
The main idea of ​​Microduino is to divide the Arduino-Uno circuit into two functional parts: Microduino-Core (minimum system board) and Microduino-FT232R (connector for connecting the board to a computer for downloading and debugging software)
Microduino is very flexible, smart, cheap, and Arduino compliant: Microduino-Core + Microduino-FT232R = Arduino Uno.
The size of the microwino is only 25.40mm X 27.94mm.
All boards have a single 27-pin U-shape, and can be mounted on each other, while the various modules do not conflict with each other.
')
All schemes and design boards are in the public domain.
Since Microduino-FT232R is only needed for downloading and debugging software, it can be used many times. The kernel itself and additional modules are cheap
The WOT network gate is a hub for distributed sensors that collect various information about the environment, such as temperature, humidity, pressure, etc. This information is transmitted to the hub, where it is processed and laid out on the network.
To make this network wireless, just connect the Microduino-nRF24, and by adding a Microduino-SD module, you can save data offline.
Microduino-LM4863 is a popular and high-quality D-Class digital amplifier.
A GPS logger requires 5 modules: Microduino-Core + + Microduino- [BT] + Microduino-SD + Microduino-OLED + Microduino-GPS.

There are three kernel modules:
Microduino-Core is based on the ATmega328P chip and is fully compatible with the Arduino Uno. When downloading and updating software using an Arduino-IDE, you can simply select “Arduino Uno” as the board type.
Microduino-Core + is a more productive version of the Microduino, based on the ATmega644PA chip, whose performance is the same as the Arduino Mega2560. Microduino-Core + supports 2 serial ports and more than 10 digital I / O.
To use Microduino-Core + in the Arduino IDE, patch it according to the instructions.
Microduino-FT232R is a USB2TTL module for connecting to a PC and downloading / updating Core / Core + software.
Microduino already supports multiple modules: network coverage, wireless, BLE, SD storage, GPS, Wi-Fi, engine, OLED display, power management, and other modules that are under testing.
Microduino-ENC - ethernet port.
Microduino-nRF24 wireless connection at a frequency of 2.4GHz.
Microduino-SD - Micro SD card slot using SPI protocol.
Microduino- [BT] - Bluetooth module. There are two versions: BT2.1 and BT4, but BT4 is the default choice.
Microduino-10DOF is a sensor module into which 3 chips are integrated using the I2C protocol: MPU6050 + HMC5883L + BMP085.
Microduino-BM is a Li-ion battery power management module that includes charging, discharging, voltage detection and LED indicators. The module supports 3.7-> 5.V and 3.7V-> 3.3V.
Microduino-OLED is a 0.96 'inch 12864-color display module that uses the SSD1306 driver with the I2C protocol and is powered by 3.3V.
Mass testing of boards (-LM4863, -CC3000, -RTC, -NEO6M, -A3906, -A4982) is scheduled to be completed in September 2013.
Microduino-solo is a test board which pins are routed to the periphery, which facilitates the development, adjustment and debugging of the connection scheme. 5.0V -> 3.3V DC-DC controller provides switching between two voltage levels with a jumper.
Sometimes increasing the number of models becomes problematic due to problems with dimensions. To solve this problem, a substrate board was created for horizontal and vertical connection of modules.
Microduino-Uno is an adapter card, by inserting the Microduino core and modules into it, you can get an Arduino.
Well, the most important thing is the prices of components
The project has already collected the necessary amount on Kickstarter . A detailed description of the composition of each of the sets on the Kickstarter is contained in this PDF file .
