Connections

(pad with golden dot next to it is pin 1):

  • 1: TX (data out)
  • 2: RX (data in)
  • 11: RESET (connect to ground to reset, pullup-resistor of 10K recommended)
  • 12: VCC (3.3V)
  • 13: GND
  • 24: LED output (ON when there is a connection, BLINKS when there isn't).
  • 26: KEY ????

  • 1 : UART-TX
  • 2 : UART-RX
  • 3 : UART-CTS
  • 4 : UART-RTS
  • 5 : PCM-CLK
  • 6 : PCM-OUT
  • 7 : PCM-IN
  • 8 : PCM-SYNC
  • 9 : AIO(0)
  • 10: AIO(1)
  • 11: RESET (connect to ground to reset, pullup-resistor of 10K recommended)
  • 12: VCC (3.3V)
  • 13: GND
  • 14: GND
  • 15: USB D-
  • 16: SPI-CSB
  • 17: SPI-MOSI
  • 18: SPI-MISO
  • 19: SPI-CLK
  • 20: USB D+
  • 21: GND
  • 22: GND
  • 23: PIO(0)
  • 34: PIO(11)

Remarque

  • le fil à wrapper est parfait pour réaliser les sondures !
  • ne pas inverser (comme moi) GND et 3.3V : le module est mort sinon !
