Yamaichi IC Test & Burn-in Socket with a simple board, specifically designed for STM32 microcontroller in QFP64(0.5mm pitch) package


  • 20-pin JTAG/SWD port and/or 4-pin USART1 interface for programming/testing
  • External crystal can be connected via on board socket for system clock
  • Onboard 32.768K crystal oscillator
  • Two LED indicators for testing, which are connected to the I/O pins via jumpers
  • All the MCU pins are accessible on expansion connectors
    • pin header pitch: 2.54mm(100mil)
