| IA1 (Bit1) | IA2 (Bit2) | Mode | Output (A+, A-) | |------------|------------|------|-----------------| | 0 | 0 | Coast / High-Z | Disconnected | | 0 | 1 | Forward | A+ = VBB, A- = GND | | 1 | 0 | Reverse | A+ = GND, A- = VBB | | 1 | 1 | Brake | A+ = GND, A- = GND (low-side braking) |

: Some later revisions or similar multiport cards use WCH (Nanjing Qinheng) chips like the CH382. If the Oxford driver doesn’t stick, try the CH38XDRV package from the manufacturer's site. Why Bother in 2026? Why are we still talking about serial ports? pi40952 3x2b driver

Previous versions suffered from ground bounce during high-current switching events. The 3x2B revision addresses this by: | IA1 (Bit1) | IA2 (Bit2) | Mode

Because the PI40952 3X2B is a hardware-level driver, "installing the driver" usually refers to one of two things: soldering the component onto a PCB or installing the that allows a microcontroller (like an Arduino, ESP32, or industrial PLC) to communicate with it. 1.
