Unbeatable ARM Cortex-M4 board for any purpose

ARM Cortex-M4 board

A good prototyping board with many features can save a day. As there are all you need you can instantly focus on things you need it to do. Aithon Robotics LLC wanted to make powerful but yet simple to work with ARM board which would fit most needs – especially in robotics. First of all it is based on ARM Cortex-M4 STM32F407 that features FPU. 512KB Flash and 192KB of RAM can be enough for most of applications. We don’t need to name all the features of ARM controller which actually caries lots of them. The board itself has 15GPIOs that are running at 3.3V but are 5V tolerant. It has 8 ADC inputs and 8 PWM outputs where you can attache servos. You can see mini-USB seen as device and USB host ports, xBee socket, Bluetooth compatible header, SPI, SWD, DAC, microSD. Robotics enthusiasts will find a 3-axis accelerometer (LSM330DLC), 2 channel 5A H-bridge, alphanumeric LCD header, buzzer, couple push buttons and couple programmable LEDs. Besides great hardware there is software library available which is based on ChibiOS/RT. So… Continue reading

The Innovative Color Detection Circuit

Those of you that loved to watch the spy or detective drama series, you must be amazed by the high tech color detection weapon/device that being used in the TV screen, isn’t it? Would you believe, if someone tells you that you can develop a compact-sized color detection circuit in within few hours? Frankly, it wasn’t some kind of joke, as you can really do it by your own. Oh, it seems that you’re wondering, “What can I do with this color detection circuit?” Well, good question! For your curiosity, you can use the color detection circuit to detect the color of an object. This is how the circuit works: By shining light of a certain color on the object and looking at how much light is reflected back, you can tell what color the object is! Ok, let say, if you’re shining a red light on a red object, that light will be reflected back instantly. Ok, now you’ve changed the color into blue, where you’re shining it on a red object, the object will absorb some of that… Continue reading
