Mach3 Jogpad

Jogpad for the Mach3 CNC control software with Maple Mini board (STM32F103CBT6). Have a look also at the MapleMini USBSerial. Communication with the PC and power supply is over a USB cable. Since the Jogpad is a USB HID (Human Interface Device) no USB driver has to be installed to the PC (as such is available on each MS Windows PC by default).

If you'd like to build a USBJoystick Device have a look at Wim's wonderful page.
