ARM Cortex-M3 STM32F103RBT6 Mini Development Board

My NXP/Philips lpc2378 died so I decided now would be a good opportunity to transition from the ARM7TDMI to the Cortex-M3.

Nice investment - $17.20 (total shipping included) from Ebay. Pictures and specs below:

 1> Main Chip: STM32F103RBT6
 2> Onboard Standard JTAG interface and reset button
 3> 2 Onboard crystals, 32.768KHZ and 8MHZ
 4> Onboard DC Regulator AMS1117-3.3: 5V input to 3.3V
 5> One RS232 serial port, UART1 and UART2 can be set by jumper
 6> all I/O lead out with marked names for further application
 7> supports USB power input(5V) and JLink Power input.
 8> Board size 71 (mm) * 93 (mm)
