    The summertime was not the best time to work on my inMoov robot, because of outdoor activities. But now it is getting cold and the Dutch weather is keeping me inside. It is time to moving forward again.

    I ordered the Nervo Boards from the http://www.inMoov.fr website. I first ordered one set, because I wanted to see what the quality was. I was happy with the quality so I ordered the second set also. First I had to figure out how the all boards supposed to fit together. For now I don’t want to use the finger sensors.
    At first I took an Arduino Mega compatible board (Funduino) and inserted the pins needed for the Nervo Board. This is done to be sure that the pins are straight and on the right position. Beware: not all the pins on the Arduino Mega board are used, so leave those position empty.

    Next I fitted the main Nervo Board over the pins on the Arduino Mega. The pins 8 till 13 didn’t fit perfectly. I don’t know of this was caused by the Nervo board or the Funduino. I had to lift one side up to bring the pin closer to the hole. I soldered all together.
    My inMoov will use the same Voltage for all the servos, so I soldered the 3 connections on the top side of the board. The solder didn’t stick very well on the pads close to pin 52. A little piece of wire was needed to make a solid connection.
    I removed the head and neck pins from the main board, because I was afraid to burn the headers on the top board. I was easier to solder the pins on the top breakout board first and then solder the 12 pin connectors. Now it was easy to solder the breakout board on the Nervo main board.
    After an evening of soldering the result is very nice. The right board doesn’t have the neck and Stomach breakout board on it. You can use an Arduino Uno instead of an Arduino Mega. You never can have enough io. 😉
    To mount the Nervo Board assemblies on my inMoov robot I printed a Mount from Thingiverse. [http://www.thingiverse.com/thing:30270]. It didn’t fit. I remove the rim around the board because I didn’t want to print another one.
    I used two 3 x 16 mm screws to mount the assemblies on the back of the inMoov. There is not a dedicated spot for it, so I looked at a spot where the two screws would fit.

    • Very nice and clean pictures Swan! This surely seems to be progressing well.
      I looked on your blog also. You seem to be happy with the Nervo board and the way they are cut with my CNC. Was the package in good shape when it arrived?
      I never had a complaint yet on my boards sold packages though, so it is more to have info.
      You are welcome to post a review on the product page of course!!

      • Hi Swan,

        Thanks for sharing your experience with the NervoBoards.
        I’m sure it’s easier how you did the Neck and Head plate soldering…
        First soldering the headers to the Neck and Head plate and after to the NervoBoard.

        About the solder-bridges in the power-line…
        Normally it must be fine to solder them without any problems.
        I will see for the next batch to update this to a bit smaller solder area.
        Hopefully this makes it more easier.
        So thanks again for your comments

        @ Gael,
        I think it’s good to update this Neck and Head soldering way to the tutorial !

        • @mdg_nl. The solder tends to flow to two of the three pads. Maybe when there is a little offset in one of the three solder areas it could flow better. The bigger solder areas have a 90 degree angle and are easier to solder.

      • @admin Thanks for the compliments. The boards where well package and survived the trip to the Netherlands easily. I have posted a review in the shop.
