Five user buttons are located on the front, each with an LED, with two more LEDs at the top to indicate activity and wireless connection. Two metal legs (supplied) can be used to stand up the board.

Refreshing stuff

The Inky Frame comes preloaded with Pimoroni’s brand of MicroPython firmware, including the PicoGraphics display library and several code examples. As soon as you connect it to a computer via USB, it’ll start a screen refresh which takes 25–30 seconds – typical for this kind of multicolour e-ink display.

By default, it auto-runs a launcher menu with five example programs. However, to run them you’ll first need to stop the launcher in Thonny and create a secrets.py file with your Wi-Fi credentials (see Pimoroni’s Getting Started guide).

An optional accessories pack adds a 3×AA battery pack (with batteries), Velcro square to attach it to back of board, 16GB microSD card, and micro USB to USB cable. You could use a LiPo battery instead, but the board can’t charge it. Still, it uses a small amount of power while refreshing, and can even be put into a super deep sleep mode with Pico W shut down – and reawakened by the real-time clock, buttons, or a trigger pin on the extension header.

Verdict

9/10

A classy colour e-ink display whose Wi-Fi connectivity greatly extends its possible uses, including as a digital photo/art frame, life organiser, or low-power smart home dashboard.
