Two channels, -0.3V to 3V, input impedance 4k ohms to a 3V bias, (models SKU204+ *) .
   −
-3V to +3V, input impedance 1k ohm to a +3V bias, model SKU199
+
(* A small number of pre-production laptops were built with -3V to +3V input range and input impedance 1k ohm to a +3V bias, eg. model SKU199. Turtle Blocks V141 and previous is correctly calibrated for these laptops but not for production laptops)
 
  −
-0.3V to 3V, imput impedance 4k ohms to a 3V bias, models SKU204+ to be confirmed
