 ## Indicator LEDs
 
 There are 3 status indicator LEDs on the board:
-- 5v Status near the USB port indicates that there is 5V present and feeding the board (D6)
-- Board Ready near the IC indicates that the board is communicating with Klipper (D1)
-- Vin status indicates that there is power present on the Vin and GND feeding the board through the screw terminals (D7)

 # Testing
 
 Included configuration file [](../Software/standalone.cfg) will allow you to startup the Expander without another MCU to validate all features are functional.
 
 You will need the following devices:
 - Power supply (5V is easiest)
 - 4 x devices for MOSFET that will work at Power supply voltage
-- Neopixel with appropriate dupont headere (WS2812b for 5V or WS2811 for 12V)
-- Display like this one: [Adafruit OLED Display](https://www.adafruit.com/product/931)
+- Neopixel with appropriate dupont headers (WS2812b for 5V or WS2811 for 12V)
+- Display (like this one: [Adafruit OLED Display](https://www.adafruit.com/product/931))
 - 2 Thermistors with dupont or JST headers
 - Raspberry Pi or another computer running Klipper

+Use the [Example](../Software/standalone.cfg) configuration supplied in this repository
 
 When the Expander starts up you should see:
 - All 3 Status LEDs light up
 - None of the MOSFETs light up
 - Neopixel will be orange
-- Display will have 3d printer typical display
+- Display will have a typical 3d printer interface

 ## Why do I want this?
 
-The Expander gives you extra connectivity that suppliments your main MCU(s) without the cost and size of a full board. Also you can use an Expander to run devices at a different voltage than the main MCU. i.e. Noctua fans are 12V where the main MCU is 24V

 ## How do I get one?
 
-Included in this repository are [Production Files](../Production_Files) which you can use to order from [JLCPCB](https://jlcpcb.com) or anywhere else you order boards from. Alternatively, on the Voron Discord you may find someone selling one preassembled if you post in #flea-market
