Hello,
Micropython supports the control of servo's.
Are there any particular type/brand of servo's that work well with the py-board?
Regards,
Roland

Re: Which Servo's
All RC style hobby servos should work. They all nominally expect a pulse of 1-2 msec sent approx 50-60Hz.
There are some high end digital servos that might not work.
And of course, the servo module wasn't designed to control servos like the ones used in CNC machines (low-end machines typically use steppers and higher end machines use servos).

To complement the previous answer, if you aren't sure what specific type you should get, you can have companies that do customization regarding servos (this one for example: http://www.powerjackmotion.com/product- ... tor-range/) to meet your requirements.
Re: Which Servo's
Those are the types of Servos that are typically used in CNC machines, which are significantly different from the RC style servos that the MicroPython Servo module supports.trazee11 wrote:To complement the previous answer, if you aren't sure what specific type you should get, you can have companies that do customization regarding servos (this one for example: http://www.powerjackmotion.com/product- ... tor-range/) to meet your requirements.

Thanks for that, I just thought their custom-made OEM products can help. Anyway, I reviewed the sight and saw the servos' standard applications are for CNC, industrial applications, and etc.

I've used two entry level TowerPro servos, SG90 and MG995.
They are not the fastest, strongest or most accurate, but they are easy to find and quite cheap.
You can find a SG90 for around $1 each. Very small and with plastic gears.

The MG995 servos are around $4 each. Bigger and with metal gears.

If you are driving a lot of servos, an I2C PCA9685 module will save you some pins and give you an external power source to drive them.
