4 Amps (2 amps x 2 motors) via a L298 motor driver
4 ADC’s (Analog inputs) via a MCP3204 chip
4 Servos with connections to power and with current-limiting resistors on the signal wires
Video-out via a standard RCA jack
Connections for an X-bee
Connections for a BlueSmirf Bluetooth unit
he 444-AVXB was designed with the robot hobbyist in mind. Connections are available for just about every “standard” thing you would find on a small to medium-sized robot. A hefty motor driver handles decent-sized motors with nice screw terminals for both power and motor connections. (4) 3-pin connections are provided for servos which can be powered by either external power or on-board power. An ADC chip allows for 4 analog inputs to be read, great for analog sensors, pots, LDR’s etc.
Video-out takes advantage of the awesome video capability of the prop and can be connected to any TV with a “video-in” and/or many of the cheapie 7” LCD screens (found on Ebay). Audio is just that, audio out with the circuit being the same as can be found on many other propeller products. Pin 15 has been brought forward as well for a Ping))) sonar unit. Finally, there is room and connections for EITHER an X-bee or Bluetooth module. All unused pins are accessible via female headers.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
