2.13 inch E-Paper HAT+ for Pi and Jetson
This 2.13 inch E-Paper HAT+ adds a 250x122 pixel two-colour display to Raspberry Pi models from Zero through 5 and to Jetson Nano. It follows the Raspberry Pi HAT+ standard so the board aligns with the GPIO header and mounting holes without adapters. An onboard high-precision RTC chip provides accurate timekeeping for logged data or scheduled refreshes. The Immersion Gold finish protects the PCB from oxidation and improves solder joint reliability.
Sustained operation with no backlight
The electrophoretic panel draws current only while the image changes, then holds the last frame indefinitely without power. This behaviour suits long-term deployments such as sensor readouts, badge displays or pwnagotchi nodes where the board may sleep for hours between updates. The RTC continues running from its own supply, so timestamps stay correct across power cycles. No backlight means zero light bleed and no additional thermal load inside an enclosure.
Upgrade from bare GPIO or smaller panels
Developers moving from raw GPIO wiring or smaller monochrome modules gain a ready-made driver circuit, mounting holes and a standardised HAT+ footprint that simplifies stacking with other HATs. The jump is worth it when a project needs persistent visibility without a powered display, accurate time-stamping, and a mechanical fit that survives vibration. Projects that require greyscale levels, partial refresh at video rates, or colour beyond black and white will need a different panel technology.

Küsimused selle toote kohta
Does the 2.13 inch E-Paper HAT+ draw noticeable power or generate heat when it runs continuously all day?
The display consumes power only when the image changes; with no backlight it holds the last content indefinitely after power is removed, so heat and ongoing draw are negligible.
Which host boards and connectors must I already have to attach the HAT+ and use the onboard RTC chip?
A Raspberry Pi with the standard 40-pin HAT+ header (Pi 5, 4B, 3B+, 3B, 2B, A+, Zero W/WH, Zero 2 W) or a Jetson Nano with the matching GPIO header is required.
Will the SPI interface on this HAT+ conflict with older HATs or GPIO accessories I keep on the same Pi?
The board follows the Raspberry Pi HAT+ standard and adds extra mounting holes, so it shares the SPI bus cleanly with other HAT+ peripherals that respect the same pinout.
