Finally found time to work on some of my #M5Stack projects.

I2C Servo Unit.

The I2C Servo Unit is almost a clone of M5Stacks official Module but instead of it being a stackable module, the I2C Servo Unit is a plugin unit that connects to the M5Stack I2C port.

The above image is how the official one looks. I have not been able to purchase one and as the circuit and code is open source, I built my own.

Sorry for the bad picture, the human holding the camera wasn’t stable.

I designed this using through hole components as a beginners kits for people wanting to learn how to solder a basic kit. This is the Revision 3 board and unfortunately has some mistakes (the data connector that is on the underside, should be on top!) it works and I’m powering it from two 18650 cells rescued from an old laptop battery.

 

My next project I have working is Photography turntable. The #M5Stack is used to drive the stepper motor and trigger the camera.

Here I am using a cheep cable remote trigger connected to the M5Stack Relay module. the screw in the trigger is a temp conductive bridge as the first two contacts need to be together in order to fire the Sony SLT A58.

This all was coded using M5Stack UIFlow programming environment and the code is as follows

Yes it is that simple!
