ALIENTEK P400 Offline Programmer Features and Specifications

The ALIENTEK P400 Offline Programmer delivers four-way simultaneous programming so you can flash up to four STM32 or STM8 microcontrollers in parallel, reducing per-unit programming time on the production floor. A responsive 4.3-inch touch screen interface lets you load firmware files, configure programming parameters, and monitor progress without attaching a laptop or desktop PC. Standalone offline operation means you store your target algorithm and hex file directly on the device, making it ideal for field service, small-batch assembly, and classroom lab environments. The unit supports a wide range of STM32 and STM8 algorithm variants, so you can switch target chips with a few taps rather than re-flashing the programmer itself. Robust voltage regulation and over-current protection circuitry safeguard both the programmer and your target boards during every programming cycle.
