# STM32F103C8T6 Dev. board
## Overview
I have had this board on a shelf for quite some time, but never used it before. Having nothing better to do this week-end, I gave it a try, and here is what I've found/done.
It's a small development board, with a 20 pins JTAG connector, a MiniUSB connector and all (?) pins broken out on two rows on the side.
There's a 8Mhz quartz (with PLL, the chip can run at 72Mhz), a 32.768kHz quartz (for the RTC), and that's pretty much all, but for only 10 bucks… It's okay 
## Bootloader
The board is shipped without any software, link, datasheet, or pre-loaded code. Luckily, the STM32 family chips often (always ?) embed a bootloader. For this chip, STM32F103C8T6, it's a Serial bootloader, which can be accessed on the top left UART header (the 4 pins next to the USB port).
I have tried flashing it with the SWD (that can be found in the JTAG header) with an ST-link programmer. I does work but requires some hardware. So the Serial bootloader…
