The latest ABX00051 datasheet (dated 16/12/2022) lists pin J1-2 as a "NC" (Table 5.1)
The latest ABX00051schematic (dated 2022-11-23) shows pin J1-2 as "MKR A5" which is connected through a 330 ohm resistor to "A2" (Sheet 5).
Which one is correct?
And what is the significance of the "MKR" designation of the connector pin on the schematic?
