  • Product DD-08477 | about 2 years ago

    Same here; got 30 1" boards that were all the same. Oh well, i’m not complaining, they’re only a quarter each.

  • News - New Product Friday: A Log… | about 2 years ago

    Do you guys ever plan to carry a connector for the Lassen GPS? It is a pain trying to connect that .05" header :/.

  • Product SEN-09418 | about 2 years ago

    You guys might want to consider adding a pullup or pulldown resistor in the next revision. Without a connection on ADD0, the sensor stops transmitting valid data whenever there is electrical interference (a finger on the connections, for example). If anyone has this problem, tie ADD0 to ground (address 72) or V+ (address 73). Also, on the arduino, 3.3V is enough to register high on the I2C bus, so no logic converter is required.

  • Product BOB-00494 | about 2 years ago

    Has anyone used this as a breakout for the Lassen IQ? The connector has a pitch of 0.5", but i’m not sure of the width.

    Looks like lots of fun. Too bad I live 8000 miles away from New York :(

  • Product DEV-10744 | about 3 years ago

    Most shields have reset buttons included.

  • Product DEV-09218 | about 3 years ago

    I’m not completely sure, but the Arduino AREF page seems to suggest the active reference voltage (5V default on this board) will be outputted to the AREF pin.

  • News - IT Update | about 3 years ago

    I remember seeing some OSHW icons on some product pages. Do you guys plan to add these to all products (that are OSHW)?

  • Product DEV-09218 | about 3 years ago

    You’re going to need more than 5.2V for the RAW pin. The RAW pin uses a regulator, which has a dropout voltage of ~1.7V. This means the board is only getting 3.5V, which is not enough. If you have to use the 5.2V supply I would suggest you get the 3.3V version.
    Another option would be to regulate to 5V outside of the board and connect to any VCC pin.

  • Product COM-10256 | about 3 years ago

    The trace is 80 mil. Assuming the copper thickness is 1 oz/ft, the board can handle a recommended maximum of 4A.

No public wish lists :(
