Konashi is a microcontroller board with a Bluetooth Low Energy (BLE) module. It is a physical computing toolkit for artists, designers and engineers who are imagining a next-generation human interface for iOS devices and tablets.

It has 8 digital input/output pins (2 of which can be used for I2C communication. All 8 pins can be used as PWM outputs.), 3analog input/output pins, and 1 UART. It contains everything needed for physical computing; simply connect it to smartphones and tablets with BLE wireless connection to get started.

“Konashi” is a traditional Japanese sweet which makers learn to make.

We chose the name for all electronics hobbyists who want to take their first step into physical computing.
