A braille cell and associated braille pin support and pin actuation assemblies are disclosed. The braille cell can include a frame, braille pins movable up and down between raised and lowered positions, and a pin actuation assembly to individually move the pins. The braille cell can include support arms, each of which having a base end connected to the frame and a pin end connected to and following a motion of a respective pin between its raised and lowered positions. The pin actuation assembly can include pin actuation units, each having a motor with a rotatable motor shaft and multiple cams mounted on the shaft, each for selectively actuating a respective pin. Each pin actuation unit can also include an angular position sensing system for monitoring, for example magnetically, a passage of the shaft through a reference angular position, and deriving information about a current angular position of the shaft.
