Inky Frame 7.3 (Pico 2 W Aboard)

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.

Revision History

• What has changed from the older Inky Frame? As of 30th January, Inky Frame is now Pico 2 W Aboard! Pico 2 W and its souped-up RP2350 chip bring some exciting improvements to Inky Frame – including a higher core clock speed, double the on-chip SRAM and double the on-board flash memory. The RAM upgrade in particular should help a bunch when working with this big display and with making requests from online APIs.

Two variants are available – Inky Frame Only, or Inky Frame with Accessory Kit. Please select an option before adding it to your cart!

• Dedicated RTC chip (PCF85063A) for deep sleep/wake
• Fully assembled
• No soldering required.

Getting Started

To make it easy to get started, Inky Frame ships pre-loaded with pirate brand MicroPython and some fun examples that use the wireless capabilities of the Pico 2 W to display interesting things.

To enable Inky Frame to connect to the internet, you’ll need to save a file called secrets.py to the Pico 2 W using Thonny. It should contain the following lines:

WIFI_SSID = ‘your_ssid_goes_here’
WIFI_PASSWORD = ‘your_password_goes_here’

To return to the launcher, hold down buttons A and E and tap reset.

Notes

• Measurements: 176.20mm x 139.20 mm (L x W)
• Overall display dimensions: 170.2 x 111.2mm (W x H)
• Usable area dimensions: 160 x 96 mm (W x H)
• These seven colour ePaper displays work best when refreshed at an ambient room temperature – between 15 and 35°. If the screen is cold you might find that the colours are less vibrant or the display is much darker than it should be.
• Due to the size of this panel and the esoteric practices surrounding suspending coloured particles in goo, there is some expected variation in colour density towards the corners. This is most noticeable when displaying block colours – green and orange in particular become less saturated towards the corners of the panel. We’ve noticed that the corners can also sometimes have a pink tinge when displaying full white (especially when the screen is cold).
• * A micro SD card can be added to cache data downloaded over wifi or for logging information before uploading via wireless. It can also be used to preload assets for your user interface. Certain tasks (like decoding a jpeg or downloading a file) require an SD card to be present as they need a large working space and wouldn’t be able to fit entirely in RAM.
• We’ve found Pico-flavoured C++/MicroPython is quite fussy about SD cards so if yours doesn’t work, try another or formatting using FAT. The cards in the Accessory Kit, or our 32GB or 64GB cards will work fine.
• ** Inky Frame’s onboard RTC (Real Time Clock) means it can be put into a super deep sleep mode that only draws about 20uA of power. Inky Frame can turn off the power that drives the Pico W and the display completely. It can be woken back up by the RTC, the front buttons or the external trigger on the extension header. You can also read the RTC to keep track of the time and date, of course!
• On the expansion header is an external trigger input. if this is transitioned from low to high then Inky Frame will wake up from deep sleep. This lets you add your own wake button or circuit or build Inky Frame into a more complicated system. The external trigger is 3.3V max.
