PP-BOB2-v1 (Discontinued, please see PP-BOB2-v2)
PP-BOB2-v1

Discontinued parallel port breakout board for CNC control, superseded by the PP-BOB2-v2; ran from 12 V DC rather than the v2's 24 V.

PP-BOB2-v2 is the current 4-axis board (plus a buffered X-slave for gantry machines), running from 24V DC with onboard relays and an isolated PWM-to-0-10V spindle output; PP-BOB2-v1 is the same board's discontinued predecessor, which ran from 12V DC and is not a drop-in swap. PP-BOB3-V1 steps up to differential step/direction outputs for longer cable runs or a noisier panel.
