During normal operation with a single USB Power Bank, ***DO NOT REMOVE*** the power jumper wire that is connected to the "AUX Power" and "Power Out" ports.
The board can be powered with a mini-USB connected to the top-left side of the board or- using the "Power-in" connection on the top-left side of the board with the included 2-pin wired connector. If using the "PENELOPE" board with the ALISHA board, connect the "Power out" from "PENELOPE" to the 2-pin "Power In" on the board.
*** Do not power the board by plugging a USB cable directly into the Arduino Nano***
***Dual USB Power Bank Operation***
If a second USB power bank is used, to support powering higher voltage servos and/or a large number of NeoPixels. You need to remove the jumper wire that connects to the "AUX Power'' and "Power Out" port. Then connect a second USB Power bank to the "Aux Power" port, this allows the second USB power bank to power to the Servo and NeoPixel Ports. The "Power-out" port on the top middle of the board can be used to power something externally if you choose, it will output the same amount of power as provided by the USB power bank connected to either the "USB Power In" or "Power In'' port on the board. When using the "Power-out" port, use the included 2-pin wired connector.
***LED Connections***
The LED outputs are separated into 'Left" and "Right". You can connect to these using the included 2-pin wired connector, the Red wire connects to the positive of your LED and the Black wire connects to the negative/ground of your LED.
***Note the "Left" & "Right" LEDs are PWM controlled, and through coding can have their intensity adjusted as well as the option to have them blink.
***Input Switch Connection***
The Input is triggered by a momentary "Normally Open" type switch, which you provide. You can use the provided 2-pin wired (either Green wire set or Blue wire set) connector to add your switch for controlling board operation.
*** You cannot use a "Normally Closed" Type Switch. If using a Limit switch, you must wire to the "C" (common) and "NO" (Normally Open) terminals on the switch. ***
***Board Operation***
The Arduino Nano is already pre-flashed with the Crashworks 3D code. Once you have correctly wired your board to your Servos and LEDs, upon initial power up the LEDs will blink and the servos will move to their home position. Upon the 1st input (button press from switch) it will let the system know you are ready for operation. Every button press after this will trigger a function to either open the helmet (turn the LEDs off) -or- close the helmet (turn the LEDs on). If you "Double Tap" the Button it will adjust the LED eyes (Off / Low / Medium / High).
***Note the USB port on the ESP32-C3 is only used for programming; you should never power the board by connecting your power supply (USB Power bank, battery, etc.) directly to the USB Port on the ESP32-C3. Also when uploading new code to the ESP32-C3 it is recommended that you disconnect the attached Servos, to prevent them from drawing power from the computer. The servos can be reconnected once you are done uploading the new code, and have disconnected from both the computer and the ESP32-C3's USB port***
*** Additional Components (Not included) ***
MG90S Servos (Recommended: Tower Pro 180 degree)
LED Eyes (Search online for "cosplay led eyes")
Momentary Switch (NO - "Normally Open" type)
Charging rated USB-Mini cable (i.e. GPS, cell phone charging)
Power bank (Recommended: 5V 2A or 5V 3A)
*** Note: We do not recommend or support powering the board using AA or AAA batteries ***
