STMicroelectronics PWM Controller

The STMicroelectronics STM32F103 family is a type of 32-bit cortex M3 full KNX twisted-pair device development kit based on the STKNX miniature transceiver. Its operating frequency is 16MHz with 128KB flash program memory. This includes originally TAPKO KNXprotocol stack KAIstack supported with AC6 openSTM32 (Linux, Windows and Mac OS-X) or Atollic TrueSTUDIO (Linux and Windows). This controller is used in automation.
