Hall based Limit Switches

At the request of folks on the mailing list I have posted the (Eagle PCB) design for the limit switches I use on my machines here:

upload:CNC-Hall%20Board.sch

upload:CNC-Hall%20Board.brd

All passives are 0603 except for C1 which is 1206

The hall is an allegro A3213 (A3213ELHLT-T)

The connector is an RJ11-6P4C Digikey A31421-ND

The board is designed such that the RJ connector can be reversed at assembly time.
