An innovate programmer--debugger with the USB interface. It supports the STM32 microcontrollers thru SWD interface. ZL30PRGv2-1 is fully compatible with the STMicroelectronics ST-Link/V2-1. It also has the function of USB-UART converter.

The programmer is working with the PC using USB interface. The ZL30PRGv2-1 is supported by popular IDE's: uVision (by Keil/ARM, for STM32), IAR Embedded Workbench (by IAR, for STM32), True Studio (by Atollic, for STM32), VX-toolset for ARM Cortex-M (by TASKING, for STM32).

Connecting the programmer to a STM32 target device

SWD signals for programming and debugging the STM32 targets are present on the IDC20 connector. Its pin-out is compatbile with the industrial 20-pin JTAG standard (as illustrated on the drawings below), so the programmer could work with any STM32 evaluation boards which uses IDC20 JTAG connector (ZL27ARM, ZL30ARM, STM32Butterfly – Kamami, Keil/ARM evaluation boards, etc).


The programmer does not support JTAG interface!

ZL30PRGv2-1 is powered from the USB connector. The supply voltage is not forwarded to the programmed/debugged target, so it needs to be supplied externally.

Interfacing UART signals to the programmer

The programmer has a Virtual COM Port (VCOM) option. RxD and TxD signals are available on the connector (as illustrated on the photo below). The drilled pads allow to solder-in Goldpin headers. By this function, the programmer can replace the KAmodRS module.
