Romeo BLE Quad is an arduino compatible robot controller based on STM32 ARM chip. It inherits all features from the Bluno M3, including wireless programming support, wireless communication between iOS/Android apps and remote control.
BT-410 is a device that enables serial communication (UART) via Bluetooth communication. BT-410 covers the circuit with a case to protect it, and it uses a connector-type cable to install on a robot and RC-100B. You can control your robot without any problems even when the infrared control condition is not optimal such as in a robot competition. The SLAVE module can be used when controlling the robot from a smart device that supports BLE (Bluetooth 4.0 Low Energy) communication.
Bluno Bee is a serial to bluetooth 4.0 module, it adopts XBEE form factor which is compact and is compatible with all shields with XBEE socket. Bluno Bee is designed to have voltage regulator which supports both 5V and 3.3V MCUs.
DF-BluetoothV3 Bluetooth module uses a unique double-board design, it is beautiful and aim to prevent electrostatic damage to the module. It is designed to have 2 DC power input, wide voltage supply (3.5V ~ 8V) and 3.3V power supply, suitable for various applications.
