Romeo BLE Quad - robot controller with STM32 and BT 4.0

Description

Romeo family evaluation kit with Bluetooth 4.0 module. It has 10 digital pins, 5 analog pins and I2C and UART interfaces. It is based on the STM32F103RET6 microcontroller, which can operate at frequencies up to 72 MHz, has a built-in 512 KB of FLash memory and 64 KB of SRAM. The board has a four-channel motor controller (2 x HR8833 chip), making the set perfect as a platform for building a small 4WD robot controlled by a mobile application. All outputs are compatible with the Gravity standard, which facilitates the connection of additional sensors and modules. The board is compatible with Arduino and can be programmed using the Arduino IDE. Full documentation is available on the product Wiki page.
