  • The problem with this board/chip is that the current line is not isolated from the electronics side of the circuit. Take a look at the ACS712 breakout board. It is totally isolated -- but be aware the Sparkfun design does not leave enough gap between the current trace and the electronics ground plane. (Look at the Allegro spec sheet.) It is a nifty board for circuits up to about 25V isolation.

    Also note that you can place a resistive shunt across the current sense terminal to increase the upper range. I use ACS712 board with a 500 amp shunt to monitor motor current in my electric vehicle.

  • Just received my two Kickstarter kits. Plugged everything into the first kit and connected to the Arduino IDE software. After loading the library, I connected to the port - /dev/cu.usbserial-DA00SWER - and "HelloWorld" worked first time out.

    Found a notification on - - that you are having some difficulties with some kits so I fired up my second MicroView. It did not run straight out, BUT i found that the port connection was at a different address - /dev/cu.usbserial-DA00SUDC. After changing the port, everything worked fine.

    Do all FTDI programming boards have a different address? This may be a bit confusing to some, but the good news is that you can run more than one programmer on the same IDE.

    Inquiring minds would like some clarification.

No public wish lists :(
