Arduino Gemma, the start of a future collaboration

Arduino Gemma Not many ago we told you how Adafruit joined the Arduino project in order to improve it and as a result we obtained the transfer of the project to the United States.

But this is not something that was born out of nowhere but it came as a result of a previous project in which both Adafruit and Arduino had worked side by side and had had very good results. This project is called Arduino Gemma.

Arduino Gemma is a circular board, similar to a coin but having a diameter of less than 3 cm. This board is fully compatible with the Arduino project and with all that it implies, that is, software and accessories. It can be connected to the pc through a microusb connection and an ATtiny85 microcontroller.

Arduino Gemma has a diameter less than 3 cm

This controller is very interesting because it has 8K of flash inside, 512 bytes of SRAM, 512 bytes of EEPROM and a clock speed of 8 Mhz. It is not a lot of capacity but it is enough to allow a lot of play to this plate. The power required is from 4V to 16V although the Arduino Gemma has a very low consumption, about 9 mAh, which means that with a normal battery we have a high autonomy. Other features of Arduino Gemma are the I / O port and the on / off button that has been installed in its latest version.

Although the best thing about the Arduino Gemma may be in its price, not just its size. Adafruit currently sells Arduino Gemma for less than $ 10 a unit, something very affordable for any pocket.

Personally I find Arduino Gemma very interesting since in addition to the large number of projects that can be done only with this board, in conjunction with any Arduino board or with another board like Raspberry Pi, the power and limits are only given by the imagination.
