It is good to know which pins the 8105 uses so as not to use the same pins in other operations. – https://forum.arduino.cc/index.php?topic=528237.0 on February 23, 2021

Nano Data Logging Shield Deek-Robot ID 8105

Feb 10, 2018, 09:21 am
Pin connection shield / arduino nano :

SDA = pin18 / A4 – clock
SCL = pin19 / A5 – clock
CS / SS = pin10 / D10 – sd card
Mosi = pin11 / D11 – sd card
Miso = pin12 / D12 – sd card
SCK = pin13 / D13 – sd card

LED L1 and L2 are not connected to anything. They can be used by wiring them to the Arduino for just any use.
