== Summary ==<br />
The Pico e-Paper 2.13 (B) is a 2.13-inch E-Ink module with 250x122 pixels and Black/White/Red colors. It connects to a Raspberry Pi Pico via SPI and requires 3.3V operating voltage.<br />

<br />
== Technical overview ==<br />
* Resolution: 250 x 122 pixels; colors: Black, White, Red; greyscale levels: 2<br />
* Operating voltage: 3.3V; interface: SPI; full refresh time: approx. 15s<br />
* Pico pin mapping: DIN→GP11, CLK→GP10, CS→GP9, DC→GP8, RST→GP12, BUSY→GP13, VCC→VSYS, GND→GND<br />
* Pixel definition: 1 bit per pixel; 1 byte controls 8 pixels; MSB format is used<br />
* For tri-color display, two separate image buffers are required: one black/white image and one red/white image, each using 1 byte per 8 pixels<br />
* SPI configuration: CPHL=0, CPOL=0 (SPI0); CS low enables the chip; DC=0 for commands, DC=1 for data<br />
* FPC connector on raw panel: 0.5mm pitch, 24-pin<br />
* Storage note: clear the screen before long-term storage and store it facing up<br />

<syntaxhighlight lang="text"><br />
cd ~ && sudo wget https://files.waveshare.com/upload/5/5a/Pico_ePaper_Code.zip && unzip Pico_ePaper_Code.zip -d Pico_ePaper_Code && cd ~/Pico_ePaper_Code<br />

<br />
== Notes and version constraints ==<br />
* Partial refresh must not be used continuously; after several partial refreshes a full refresh is required, otherwise the display behavior can be irreparably disturbed<br />
* Tri-color EPD shows slight color differences between batches; clear the screen content multiple times before powering on<br />
* Do not leave the screen powered on indefinitely; set it to sleep mode or power off when not refreshing, otherwise the screen remains under high voltage and can be damaged<br />
* Recommended refresh interval: at least 180s between refreshes and at least once every 24 hours<br />
* After entering sleep mode, sent image data is ignored; re-initialization is required<br />
* Border color adjustable via register 0x3C or 0x50 (see datasheet for details)<br />
* Raw panel may require a level converter for 5V environments; newer driver boards (from V2.1) support both 3.3V and 5V<br />
* FPC cable is fragile: bend only horizontally, not vertically; protect the screen from drops, impacts and hard pressure<br />
