  • Note 1) Please check here for the specifications of Spresense main board, Spresense extension board and Spresense camera board.
  • Note 2) To use the UART interface, the Wi-Fi Add-on board iS110B board version V1.0C must be used. In addition, the UART interface of the Spresense main board and the Spresense extension board cannot be used simultaneously.
  • Note 3) The operating voltage of pin socket JP2 and JP13 on Spresense extension board can be set to 5V or 3.3V by changing the position of the jumper on JP1.
    Spresense extension board operating voltage is set to 5V when shipped.
    Please check here for details.
  • Note 4) For the power supply method to Spresense board (when using Spresense extension board), please check here.
    For the method of supplying external power to Spresense main board, please check here.
  • Note 5) Please check here for specifications of Spresense Wi-Fi Add-on board iS110B.



Pinout

The function pins of Spresense extension board with Spresense Wi-Fi Add-on Board iS110B (manufactured by IDY) are as follows.
I2C_SCL, I2C_SDA, PWM × 4 inside of the red frames are available.
There are limitations when using TX and RX inside of the blue frames.
Please check Appendix when using UART interface.

  • Note 1) It can be used as a GPIO or PWM output port, but the function is switched in units of Pin46-47 and Pin48-49 groups. For example, if Pin46 is set to PWM, Pin47 will also be set to PWM.
  • Note 2) To use the UART interface, the Wi-Fi Add-on board iS110B board version V1.0C must be used.
  • Note 3) Pin99-100 is connected to LED2-3 on the Spresense main board. Therefore, the GPIO operation mode can only be set to 4(OUT:PUSH-PULL:PULL-DOWN). These two LEDs can be used arbitrarily.

About User Console Mode

When you open the COM port, Welcome to neqto !!! is displayed and the countdown from 3 to 1 starts.
Pressing any key on the keyboard during the countdown activates User Console Mode.
User Console Mode provides a command console interface using the UART interface.
It can be used for inputting various setting commands and displaying real-time logs.
