Packet serial to R/C servo w/ absolute encoder This is for one of my robot projects. Features: TTL Serial interface, PWM output w/ 1/2 microsecond resolution, Current sensing, Absolute encoder SPI interface. Features will be added as needed. The Rev B PCB is being printed 6/19/2018
ToDo:
Add params:
Mode 4, Gripper control, closed value, open value Move toward close until reached or max current Open to open value OpenValue = FastRevVal, CloseValue = FastRevVal Speed is used for close only Open may be greater than or less than close, RevDirFlag?

Questions
How big is the SerialServo PCB?
It measures 28.6 × 48.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SerialServo use?
32 parts, built around the LM358AP. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SerialServo KiCad files?
From the DavidMFlynn/SerialServo repository on GitHub, at the commit this page was made from: the board is SerialServoMiniPCB/SerialServo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SerialServo design in my own project?
Its repository states no licence, so its author keeps all rights: ask DavidMFlynn before reusing the design.
