Logic Converters

Muchos dispositivos electrónicos utilizan un voltaje lógico de 3.3V. Por que Arduino Uno no sirve por estos voltajes es necesario usar un convertidor que posibilitará el cambio de una voltaje a otro. Existen dos tipos de convertidores lógicos uni-direccionales y bi-direccionales. Convertidores uni-direccionales tienen todas las entradas asociadas a un voltaje, y salidas al otro. Convertidores bi-direccionales tienen tanto entradas y salidas en cada valor de voltajes. Convertidores bi-direccionales pueden ser también aútomaticas y intercambiar puertos de salida con los de entrada dependiente del signal.

Bus Pirate - v3.6a

SP037

Bus Pirate - v3.6a

This little board is great for any type of prototyping - enables troubleshooting and debugging of any board with voltage from 0 to 5.5V. The  board interprets the commands and sends them further via a proper protocol (ranging from UART through I2C up to HDD44780 LCD). The Pirate lets analyze as well the data sent back from the device to the computer terminal effectively allowing to decipher potential errors. The bootloader installed on the board enables the quick and easy update of firmware and changing the functionality of the board.

This board features PIC24FJ64 and FT232RL USB-to-serial chip enabling swift communication over the mini-B USB port. On the other end of the board 2x5 pin header is placed with detailed descriptions of each pin.

Optical Isolated Converter...

C0015

Optical Isolated Converter FT232RL USB 2.0 to RS485

This converter has an internal DC / DC supply and a total isolation between the USB and the RS485 output and allows to establish a reliable and safe communication.
Its FT232RL component has excellent compatibility and a communication rate up to 3M for a maximum distance of 1.2 km. The RS485 output interface uses an optical coupler with high speed for an optical insulation of 1500V and a protection against lightning of 600W: these characteristics allow to protect the computer from the potential damage of static electricity, lightning, over voltages and ground faults. Optical Isolated Converter FT232RL USB 2.0 to RS485 features:
- Required systems: WINDOWS CE / 2000 / XP / VISTA / WIN 7 / LINUX / MAC OS
- Internal DC />

Level converters

Microcontrollers and peripherals often work on different logic levels - that is a 1 signal is indicated by a 3.3V in some circuits and by 5.0V in other. To make them "talk" to each other you need to bump up the signal or lower it down. And that is where level converters come into play. The easiest way to go about it is to get a bi-directional making it universal and easy to connect the circuit both ways - from higher to lower voltage and the other way around.

USB converters

Another "difficulty" in connecting and in general getting around with your new Arduino or any other controller might be connecting it to your PC or laptop. We are all well used to the USB ports and it is not surprising by all means. They are fast, they convenient. However, back in the day there plenty of standards used for communication and interestingly most of them are still used, even though maybe not in such popular uses. The two most used standards of transmission are RS232 and RS485 - often served by a popular 9 pin DB connector. However, for the development boards, what is the most probable is that you will be playing with straight 4 pin TTL connection. There is a range of controllers allowing for this conversion - starting with the class, quality and reliability of FT232 by FTDI through PL2303 through CH340. You name it we have it, in all price levels and from range of renowned and a bit less renowned producers!

ATmega programmers

Last but not least, you might not only need to connect your board to a laptop, but as well to program the ATmega on it. Well, you will need yet another equipment for that. ATmega programmers come in all kinds and with range of different functionalities. Revise our offering, and find an easy to use and effective microcontroller programer
