Hw-044 Datasheet ((link)) -
Whether you are controlling a robot, designing a custom gamepad, or building an interactive art installation, the HW-044 delivers reliable, low-cost, dual-axis analog control. Bookmark this page as your reference datasheet, and always remember to calibrate your readings in software for the best results.
Note: Pins 1, 4, 6, 7, 8, and 9 are structurally present but typically unrouted/tied together internally on basic HW-044 modules, as hardware flow control (RTS/CTS) is bypassed in favor of simple three-wire communication. Functional Block & Schematic Breakdown
