HY-TinySTM103T is entry level development board for the ARM Cortex M3 family of devices produced by ST Microelectronics Inc. With HY-TinySTM103T you can explore the features of STM32 family on budget, the board have everything necessary to build simple applications: USB port where power is taken and power supply circuit, reset and oscillator circuits, SWD/ISP for programming and debugging, one status LEDs and reset button.

Although very simple this board will allow you to easily build USB application like PC mouse, USB mass storage device, USB Audio class device, USB to Virtual RS232 port. There are plenty of GPIOs on extension headers where you can connect your additional circuits.

Important, SWD interface subject to schematic, not PCB screen printing. ISP PIN order is GND, SWCLK, SWDIO, UART1-RX, UART1-TX, 3.3V.
