Now it is sort of an interesting question/comment to myself (and others).
Ok So I made a version of the Servo library that works for up to 24 servos... The question to myself is do I have enough curiosity to actually try it out... Anyway I went to look to see if I had some of my earlier T3.2 Servo boards sitting around and if by chance I actually socket-ed the T3.2... The unfortunate answer is no... I do have a few T3.2/LC boards with 3 pin headers where I used a socket, but with these boards I hard wired either 3.3 or 5v to the power pins... (I did try out one of these boards with T4...) And the things I tried worked...
I did not try the sound or AX servos... I think I hacked up this board when the LC was in beta.
But some of the earlier boards I did when I still was doing RC servos, all of the ones I found had the Teensy soldered into the board... If desperate, could probably unsolder... Also could maybe look in the different boxes and the like in my cabinet to see if I kept any of the unpopulated boards... But I were to do this, I would be more likely to want to simply order new boards...
And if I were to order one, would I want one like below which I did for XBees or one with Arduino Shield like pinouts, like I did a version of later?
And if I were going to order again what all should I change? Some possible maybe simple things include?
a) This one is setup to use pins 9/10 for XBee. Why Serial2 works better on Serial3 on T3.x. BUT These pins are not Serial pins on T4, so logically should move to 7/8 which are. OR could just rely on Jumpers. OR sine 9/10 are FlexIO pins and I have a FlexIO library, which includes SerialIO, could put this to use...
b) Sound - I just had simple buzzer and simple transister setup for sound, which is setup to jumper off of pin 6. Is this still a good choice?
c) What to do with underlying pins? depending on usage I would maybe:
1) add the 10 SMT type pins ...
2) Probably hook up USB
3) Probably punt on SD pins?
d) Other Servo type connectors... This had one from of Robotis AX servos, not sure if level shifted or not... For this I might be tempted to:
1) Either punt for These servos although they are what I mostly use. (Would probably use different level shifting including both pins 0/1...
2) Maybe optionally have setup for Robotshop new servos with 4 pin connectors.
Again hard to know where to draw the line?
