RAK5005-O, RAK4361, RAK13002 and RAK14000 nrf82540 used pins?

[mark.birss]

What is the actual nRF82540 pinouts used for the

The circuit diagrams do not show the connection to the nRF82540 soc ?
Is there more complete circuit diagrams available ?

• RAK5005-O
• RAK4361
• RAK14000 e-paper
• RAK13002

Hello @mark.birss , welcome to the forum.

As there are many modules, we do not have a connection diagram for each single combination.

WisBlock Core to WisBlock IO slot is 1-to-1 the same

And the WisBlock Core to WisBlock Slot A/B/C/D is like this

When writing your code with ArduinoIDE, you have the IO’s defined in the variant.h file

	/*
 * WisBlock Base GPIO definitions
 */
	static const uint8_t WB_IO1 = 17;	   // SLOT_A SLOT_B
	static const uint8_t WB_IO2 = 34;	   // SLOT_A SLOT_B
	static const uint8_t WB_IO3 = 21;	   // SLOT_C
	static const uint8_t WB_IO4 = 4;	   // SLOT_C
	static const uint8_t WB_IO5 = 9;	   // SLOT_D
	static const uint8_t WB_IO6 = 10;	   // SLOT_D
	static const uint8_t WB_SW1 = 33;	   // IO_SLOT
	static const uint8_t WB_A0 = 5;		   // IO_SLOT
	static const uint8_t WB_A1 = 31;	   // IO_SLOT
	static const uint8_t WB_I2C1_SDA = 13; // SENSOR_SLOT IO_SLOT
	static const uint8_t WB_I2C1_SCL = 14; // SENSOR_SLOT IO_SLOT
	static const uint8_t WB_I2C2_SDA = 24; // IO_SLOT
	static const uint8_t WB_I2C2_SCL = 25; // IO_SLOT
	static const uint8_t WB_SPI_CS = 26;   // IO_SLOT
	static const uint8_t WB_SPI_CLK = 3;   // IO_SLOT
	static const uint8_t WB_SPI_MISO = 29; // IO_SLOT
	static const uint8_t WB_SPI_MOSI = 30; // IO_SLOT

Thank you, I just saw this also with your recent bootlaoder update
