The parts have arrived for this project! The three XIAO boards cost $17.33, were ordered on 04/10/2025 and landed on 04/17/2025. 1 The 2.9″ e-ink display cost $24.99 from Waveshare, were ordered on 04/11/2025 and landed on 04/14/2025.23
I’ll need to solder in the headers for one of the XIAO chips, connect it via jumpers to the e-ink display, and then see if I can update the screen with content. For now, I’ll just power it with USB until I get it working, then solder in a LiPo connector.
Sticky Note Timer- Ah, just what I need! A new project!

- This price includes shipping and after a $5 welcome coupon code for my first order [↩]
- Again, this includes shipping [↩]
- I’m not without some degree of self-reflection. I’m ~$45 deep on this project which would buy four kitchen timers and 4,000+ sheets of off-brand sticky notes. But, what price knowledge? WHAT PRICE KNOWLEDGE?!?!? [↩]
