From the project
Spectra 6 and 4 gray E-paper frame
StickyPix is a small, rechargeable e-paper picture frame that lets you send images from a phone or desktop app over Bluetooth Low Energy. The same product family supports a four-gray black-and-white display and a six-color display.
StickyPix is developed as a complete hardware and software product:
1. Choose an image in the Flutter app. 2. Crop, rotate, and adjust the image for the selected device. 3. The app converts the image to the display's limited palette using dithering. 4. The processed framebuffer is sent to the device over BLE. 5. The device refreshes the e-paper panel and returns…

50p spectra6 4 copy: common questions
What microcontroller does the 50p spectra6 4 copy use?
The 50p spectra6 4 copy is built around the NRF54L15-QFAA-R, from the Nordic nRF family.
How big is the 50p spectra6 4 copy PCB?
The 50p spectra6 4 copy measures 54.5 × 47.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the 50p spectra6 4 copy?
