* D+ pull-up R=1.5K, crystal = precision clock resonator

Original STM firmware (doc AN2606).

This board is ARM Cortex-M3 Minimum System Development Board - STM32F103C8T6.

Board build on STM32F103C8T6 - STM32 microcontroller with ARM Coretex-M3 32-bit core.

Logic level - 3.3V

Board connects to the computer via micro-USB cable (used for almost all Android smartphones). You can supply power to board through the Micro-USB connector or to power pinheaders. The voltage regulator (LDO) can deal with incoming voltage from 4V to 8V DC. Output current for 3.3V - about 180mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects.
