To use the E-Stop option, connect an E-stop switch (closed when OK, open in stop position) that feeds 12v to position 40 of this adapter board. The E-Stop switch must break the 12v signal of the circuit when the e-stop is pressed or if a wire breaks. Other methods are not recommended for safety. This is to guarantee it shuts the inverter down when needed. Starting with V0.0.4 '''pin 26''' of the 40 position connector has a '''solder jumper to 12v'''. This allows the user to connect on board '''+12V to pin 26''' to be used as the +12V supply for the E-Stop Switch. See p26 +12V below.

			=== OI Automatic Mini Maniboard Address Detection ===
			Automatic board detection was introduced with this board in combination of the Mini Mainboard. [[Mini Mainboard#Hardware detection]] '''There is nothing to do here''', the Open Inverter environment should automatically detect which board this is and populate settings for it. This sense line is shared with the brake output, see the "Brake Output section at the bottom for more info.

You must use only one style jumper to select 3.3v or 5v for your programmer so you do not accidently short 5.3v and 3.3v together. J8 has 2.54mm pin spacing, common jumper caps will work to select the voltage. See programming the ESP32 below for further info on programming.		are voltage select jumpers.
