Hello,
I have some short questions. Is it possible to wire the "Adafruit Trinket" with the "Adafruit 16-Channel Servo Board"?
If yes, would it be correct to wire Pin #0 -> SDA and Pin #2 -> SCL?
And the other question is. How do I would have to wire a USB-LiPo charger board in to the circuit?
May if I would use a 6V LiPo for the 12 Servos I would like to use.
I just have to check first before I do the order.
Thanks for any help.

Our LiPo chargers only work with 3.7v 1S LiPo cells. We do not have a 6v charger.How do I would have to wire a USB-LiPo charger board in to the circuit?

We do have the PowerBoost 1000 C, which will provide up to 2A of 5v power from a 3.7v cell. But that is not enough power to drive 12 servos.

Re: Adafruit 16-Channel Servo Boader & Adafruit Trinket
okay, thank you for the quick answer.
But I have another question.
When I'm done with the Project maybe I want to add a bluetooth Board to control.
Would it be possible to connect the Board with the Trinket?
Or do I have to take another one right from the beginning?
The requirement is the Board should not be to big and heavy

It's possible to connect a Trinket to an EZ-Link through a SoftwareSerial connection, but it's a bit easier to use a Pro Trinket. That uses the same microcontroller as the Arduino Uno, and is only a little larger than the Trinket.

Perfect thank you.
There is another question again about the powering.
Is it possible to use 2x Li-ion with 3,7V -> (7,4V) to powering the 16-Channel Servo Board or is that to much for the connected servos?
And would it be possible to charge the 2 Li-ions with the LiPo charger borad?
At the Servo Board I should use a 1200µF capacitor. At home I already have a 2200µF capacitor, could I also use that one or is it to big?

Re: Adafruit 16-Channel Servo Boader & Adafruit Trinket
It would be too much for the servos, and you generally want to avoid putting LiPos in series or parallel unless you have a pack that was matched at the factory.W3ST wrote:Is it possible to use 2x Li-ion with 3,7V -> (7,4V) to powering the 16-Channel Servo Board or is that to much for the connected servos?
A better option would be to use a single LiPo with a boost converter like the PowerBoost 1000: https://www.adafruit.com/products/2030 You might need more current than the PowerBoost 1000 can put out though. Pololu has a good selection of higher-current boost converters: https://www.pololu.com/category/132/ste ... regulators
Again, it's usually better to stick to a single LiPo if you aren't using a pack matched at the factory.W3ST wrote:And would it be possible to charge the 2 Li-ions with the LiPo charger borad?
2200uF will be fine. It's a debounce capacitor, so bigger is better.W3ST wrote:At the Servo Board I should use a 1200µF capacitor. At home I already have a 2200µF capacitor, could I also use that one or is it to big?
