5V PWM output ports [G, S, V] can be used for multiple purposes. The plan is to add 3x more 3pin ports (XH2.54) to the board. The change in hardware will allow more functions to be implemented on the OpenTrickler chassis.
Dedicated Neopixel RGB chains for chamber lightening and status indication, apart from the ones from the mini 12864.
Spare ports for servo motors, for example, MG90S to drop/lift drop tube or open/close the charge port gate.
