Pimoroni Explorer: Wifi Module Question

Support
6

Hi all,

So I’ve gone and purchased the following:

  • 8 Pin JST-SH Cable (SP/CE)

  • RM2 Wireless & Bluetooth Breakout (SP/CE)

  • Jumper Jerky Junior

I’ve connected the Jumper Jerky’s to the 8 Pin JST-SH Cable (SP/CE) and then connected that to the RM2 Wireless & Bluetooth Breakout (SP/CE).

Just wondering if anyone can help explain the next steps:

The SP/CE connector has the following [my cable colours]:(N/C [Red], 3V3 [Orange], CS [Yellow], SCK [Green], DAT [Blue], WL ON [Pink], GPIO0 [Brown], GND [Black]).

I’ve looked online for the meaning of the above and got the following:

Pin Definitions

  • N/C: Stands for “Not Connected”.

  • 3V3: Refers to a 3.3V power supply pin.

  • CS: “Chip Select” pin. Used to communicate via SPI.

  • SCK: “Serial Clock” pin. Used to provide timing for serial data transfers, often found in SPI interfaces.

  • DAT: “Data” pin. Generic data signal pin.

  • WL ON: “Wi-Fi On” or “Wireless LAN On” pin. Enables the Wi-Fi.

  • GPIO0: “General Purpose Input/Output” pin, specifically GPIO number 0.

  • GND: “Ground” pin.

The Pimoroni Explorer itself has a Breadboard and a separate GPIO section with the following:

GP0, GP1, GP2, GP3, GP4, GP5

ACD0, ACD1, ACD2, 3.3V, GND, GND

Do I need to use a mixture of the breadboard and the GPIO section?

Or just solely the GPIO section? If just GPIO I take it I plug the BLACK cable into the GND connector, ORANGE into the 3.3V connector, BROWN into the GP0 connector and I leave the RED cable dangling.

For my other four cables I need to reassign the GP1 through GP4.

Am I on the right lines?

Any further advice or guidance is much appreciated.

Thanks!
