Picture	Description
	Main components. Additionally, 2 100 Ohm resistors and pin header not in the picture
	Pin soldering ESP32 C3 CORE and Air 101 display
	Screw the display to the round part
	This is how it looks from the outside
	Wiring scheme
	Wires connected to the ESP32
	TSL2591 and AHT21 with wires
	Chassis mounted, except TSL2591 top support and round front (display)
	Complete chassis with wires
	Complete chassis with wires (PCB side)
	Complete chassis with wires (charge regulator side)
	MCP battery charge controller
	MCP connections detail
	Stick battery and regulator with double side tape and connect the Dupont connectors LOAD(blue) and GND (white)
	Solder USB-C wires and yellow wire for battery monitoring (protected with tape)
	Prepare the PCB with 4 blocks of 4 pins. Here is the PCB front, with connections for 3.3V / GND / SCL / SDA
	PCB back, joined pins of each block
	Fix PCB with 4 screws and connect the dupont cables for the sensors: SDA (purple), SDL (green), 3.3V (orange), GND (brown)
	Use one screw to fix the AHT sensor and pass the 4 wires to the PCB side
	Pass the wires of TSL2591 on the top side of the chassis
	Screw the sensor TSL2591
	Connect the wires from both sensors in each block of colors
	Solder both white wires to the switch
	Front complete (display, switch and USB-C port)
	Top support for TSL2591 with screws and wires
	Top support fitted in the upper part
