    the robotics 101 videos are great! I’m very glad Sparkfun is carrying the Actobotics line. I noticed in today’s robotics 101 video it was mentioned that Sparkfun is not carrying the Makerbeam products anymore. Is it also planned to stop carrying the Microrax products as well? While there may be some limitations of microrax compared to actobotics parts, the microrax / makerbeam products serve for smaller structures and smaller robots whereas, IMO, Actobotics seems to shine for bigger robots and structures.

    A little tip I learned about NPN vs PNP transistor schematic symbols. NPN stands for “Not Pointing iN”. PNP stands for “Pointing iN Pointer”. Not sure if you ever heard of those or not, but thought I’d comment anyway.

    Can’t wait to give the 4ch bidirectional logic level converter a try! Been using the TX lines (the bidirectional part) of the older logic level boards and wished I had more bidirectional lines, now I have them!

  • Product BOB-08745 | about a year ago

    Well, I’m going to comment on this product. Generally it is great to have and I’m using it on several circuits. I have found that, when using the RX lines (since they are simple voltage dividers) that in a few (not very often) situations, the shifted voltage does not work correctly for the low voltage receiving device. I have been agonizing over why serial data from a GPS chip is not seen by an ARM processor’s UART. I finally switched over to use the TX (really bi-directional) line and now the data is coming through. If Sparkfun has the opportunity, though it may up the cost of this cute board a little bit, but I would suggest they use the MOSFET circuit’s on both data directions for more accurate level shifting.

    Does this have level shifters on it so that it is compatible with 5v logic?

  • Product WRL-11176 | about 2 years ago

    So, I have a question, I see there is a voltage regulator on this board (by looking at the schematic). The question I have is if I have my own external 3.3V regulator, can I power this board directly from that by hooking it to one of the 3.3V pins on the board (like near where the “Power” label is on the board. I would appreciate it if someone could answer this. I’m planning on hooking this up to non-Arduino stuff and want to make sure I get the power, etc hookups right.

    Are these standoffs compatible with Makerbeam bars? Just curious – if they are, you should say something about that in the product description

    I’d like to thank Sparkfun for offering another option into the Synapse RF line of modules. This looks like a great complement to the other Synapse product you offer and appears to provide greater communication range than the other. I’m getting interested in trying these.

  • Product WRL-11279 | about 2 years ago

    It’s very cool to see this product being sold by Sparkfun. I wonder if Sparkfun would consider supporting the other Synapse modules (RF100 / RF200, etc) with a breakout board similar in concept to the XBee Explorer Regulated product.

    This is interesting. The “product brief” from the manufacturer says “up to 3 miles” but the datasheet (as you point out) on the very same product gives the 4000 feet number. Two different specs, on the same device, in different documents from the same company. Seems like the manufacturer may have misprinted something in one of them (I suspect the 4000 ft number is probably the more correct one). Sparkfun, or someone, may need to do a double check on that.

No public wish lists :(
