I would like to use the below components together in a solution. Specifically, I would like to send data to a “slave” unit from my Rak solution using I2C (or another available GPIO protocol & pin set) e.g. connect my Rak solution to an Arduino.
I have used the Rak pin mapping spreadsheet and it has flagged a number of IO conflicts.
My solution build:
|Component Type||Rak Ref ID||Component Name|
|Base||RAK19007||WisBlock Base Board|
|Core||RAK4630||WisBlock LPWAN Module|
|I/O||RAK1920||WisBlock Sensor Adapter|
|SLOT A||RAK1910||WisBlock GNSS Location Module|
|SLOT D||RAK1904||WisBlock 3-axis Acceleration Sensor|
The pins conflicting are:
According to the RAK4630 - WisCore datasheet, the Core has two sets of I2C pins (i.e. I2C_2) can I reassign RAK1920 to use PO.02_I2C_2 & PO.25_I2C_2 on the RAK4631/0 WisCore?
Also to avoid further conflicts, can I switch off the use of pins on RAK1920: IO1_Gove; (TX, RX & EN5V and INT Mikro; PIN1_I2C and PIN2_I2C)?
Please see my pin mapping output for further details.
