+There's a new ePaper screen in town, and it's a biggie! Inky Frame 7.3" features a **super crisp E Ink display** with 800 x 480 pixels of seven colour goodness. We've added **five buttons with LED indicators** for interacting with the display, **two Qw/ST connectors** for plugging in breakouts and a **micro SD card slot** for storing photos of fond maritime adventures (or whatever floats your boat).
+
+Every Inky Frame comes with a pair of sleek little **metal legs** so you can stand it up on your desk (and a selection of mounting holes if you'd prefer to do something else). There's also a **battery connector** so you can power it without annoying trailing wires, and some **neato power saving features** that mean you can run it from batteries for ages.
+
+Here are some things we reckon this mahoosive Inky would be great for:
+- An ultra readable, low power consumption home automation dashboard
+- Displaying stylised photos, pop art images or favourite comic panels.
+- Showing cute graphs and readouts from local or wirelessly connected sensors
+- Displaying fascinating data from online APIs.
+
+## Features
+
+- Raspberry Pi Pico W Aboard
+  - Dual Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM
+  - 2MB of QSPI flash supporting XiP
+  - Powered and programmable by USB micro-B
+  - 2.4GHz wireless
+- 7.3" EPD display (800 x 480 pixels)
+  - E Ink Gallery Palette® ePaper
+  - ACeP (Advanced Color ePaper) 7-color with black, white, red, green, blue, yellow, orange.
+  - Ultra wide viewing angles
+  - Ultra low power consumption
+  - Dot pitch – 0.2 x 0.2mm
+- 5 x tactile buttons with LED indicators
+- Two Qw/ST connectors for attaching breakouts

+## About Pico W Aboard
+
+Our new Pico W Aboard products come with a **built in Raspberry Pi Pico W**. This means you get all the advantages of a RP2040 microcontroller - a speedy fast dual-core ARM processor, a dynamic, growing ecosystem and a choice of different programming methods to experiment with. Most excitingly though, Pico W has **wireless connectivity**, so your Pico/RP2040 devices can communicate with each other, and the internet
