    Basically a breakout board for the processor. Includes USB connection (2x 22Ohm resistors in series with D+ and D- and a D+ pull up resistor connected through jumper P2). All pins nicely labeled. Includes 8MHz and 32kHz cystals, power LED and 20 pin JTAG connector. Boot 0 and 1 pins brought out to 2.4mm pin header for boot mode selection. Serial connections have their own 4pin header with GND and 5V. Nothing else. A good point is V_BAT is brought out to pin header as well. Schematics can be found

    Great board for the best price. The Cortex-M3 CPU is great, very powerful and the chip has tons of periphery. I like the fact the board has the RTC xtal mounted. Great open source support - libopencm3 + GNU ARM toolchain + Eclipse. + OpenOCD.

    ARM Cortex board purchased for some experiments. not yet tested, only powered with the USB cable. the board quality is good, but the microprocessor look scratched and with the label and printing misaligned, so it could be not really genuine. I will check as soon as possible. Scheda ARM Cortex acquistata per alcuni esperimenti. non ancora testato, alimentato solo con il cavo USB. la qualità della scheda è buona, ma il microprocessore sembra graffiato e con etichetta e stampa disallineate, quindi

    I have seen it listed on other sites but not a this this price. I connected it to J-link JTAG,USB power , Open KEIL, compile test project and it worked. Just as I was expecting.

    Zum Download über TX RX die Bootjumper *- BOOT0 -* BOOT1 so stecken. Nutze dafür den CH340 in NANO (Achtung Widerstände anpassen sonst langen die Pegel nicht und RESET jumpern) Es gibt nun auch noch eine schmälere Version.

    con este tengo problemas ya que necesia de otro modulo para programarlo y este modulo es caro asi que creo que no lo comprare, estoy desilusionado con esto

    A lot free utilities are available for this MCU. There is no pre-flashed bootloader but the price of ST-LINK here is very good. With both of them for less than 10$ you can do a lot of project.

    Tested with some small project with GNU ARM compiler and Open CMSIS library. Very good results. Thanks for good product.

    Perfect small board to start with STM32 development, well constructed and has everything required...
