SerialShot – new protocol for ESC
Matek has developed new ESC protocol – SerialShot. The idea is to use bidirectional UART to communicate with the microcontroller on the ESC. This enables to communicate with the ESC and have a telemetry readouts by using only two wires (RX, TX) for all the 4 ESC’s. This should simplify the wiring of the 4in1 ESC to Flight Controller. Another advantage of the SerialShot is that it enables to use only one MCU for driving all 4 ESCs while usually every motor ESC has separate MCU and separate signal wire.
SerialShot will simplify the 4in1 ESC design and probably make them cheaper to manufacture. It is not known if this protocol can be used for the separate ESC’s or if it can only be used for 4in1 ESC.
Matek has also posted a teaser photo of their first 4in1 ESC with only one F4 MCU that drives all 4 motors by using SerialShot.
Here is the demonstration of the new Matek 4in1 ESC working on SerialShot.
Update 2019-12-30: Matek has not abandoned this project, but in fact there is major progress in it – Serial Shot 4in1 ESC main MCU has been upgraded to the F7 (F722) and some prototypes have been manufactured. See the latest photo.

Anything more heard about this?
Nothing heard since. Matek made a prototype of this ESC, but it was never released. It’s a pitty as this was realy good idea.
I will try to ask Matek what happened to it.
I’ve just got response from Mateksys – they say the project is not abandoned and they have changed the F4 MCU to F7 and currently are testing it.
