WIZ105SR-EVB​

  • WIZ750SR-105 Developer Interface Board.
  • RESET Tact SW.
  • FACTORY RESET SW.
  • BOOT0 Slide SW.
  • H/W Trig Slide SW.
  • RS-232C Transceiver, D-SUB9-MALE.
  • 5V DC-JACK (External 4.5pi, internal 1.3pi)
  • inside LDO 3.3V (5V to 3.3V)

WIZ750SR-105 EVB is must use the WIZ105SR-EVB Because WIZ750S-105 is a replacement for WIZ105SR.
