Align the E-paper 24P Shield pin headers with the matching sockets of the Arduino mainboard and, after confirming the orientation, press straight down.

			2. According to the selected e-paper screen, choose P2 jumper value 2.2 Ω or 0.47 Ω.

			3. Insert the e-paper's FPC 24P flat cable with its metal contacts facing up into the P1 slot, then press the connector latch firmly closed.

			4. Supply power via USB or an external source to the Arduino mainboard; the screen automatically enters the refresh-standby state.

			 Plug and Play: using the universal Arduino pin-header interface, it stacks directly onto Arduino UNO / Leonardo / Mega and other standard mainboards.

			 Multi-Screen Compatible: via the FPC 24P interface, it supports various 24P e-paper modules (black/white / black/white/red / black/white/red/yellow etc.).

			 Vendor Compatible: via the P2 jumper, select 2.2 Ω / 0.47 Ω resistance to match different vendors' e-paper screens.

			 Low-Power Friendly: an e-paper screen consumes zero power for static display, ideal for battery-powered IoT labels, price tags, reminder boards and similar scenarios.
