+
+| Pin  | Signal | Function        |
+| ---- | ------ | --------------- |
+| PWM9 | PA4    | Battery Voltage |
+| PWM8 | PA7    | Current Meter   |
+
+## Voltage Monitoring
+
+The Sparky has no battery divider cricuit, PWM9 has an inline 10k resistor which has to be factored into the resistor calculations.
+The divider circuit should eventally create a voltage between 0v and 3.3v (MAX) at the MCU input pin.
+
+WARNING: Double check the output of your voltage divider using a voltmeter *before* connecting to the FC.
+
+### Example Circuit
+
+For a 3Cell battery divider the following circuit works:
+
+`Battery (+) ---< R1 >--- PWM9 ---< R2 >--- Battery (-)`
+ 
+* R1 = 8k2 (Grey Red Red)
+* R2 = 2k0 (Red Black Red)
+ 
+This gives a 2.2k for an 11.2v battery.  The `vbat_scale` for this divider should be set around `52`.
+
+## Current Monitoring
+
+Connect a current sensor to PWM8/PA7 that gives a range between 0v and 3.3v out (MAX).
