Atmel SAMD21G Sensor Board

Mike Rankin created this tiny sensor board with an ARM Cortex M0+ microcontroller and OLED display: 0miker0’s Blog: SAMD21G Sensor Board It’s pretty tiny so a 4 layer board made the whole job easier. The top and bottom are pretty much dedicated for components, layer1 are tracks and power traces, layer2 is a ground plane. Mixing up an internal plane and routing layer was interesting. The hardware consists of ...

Tiny Message Board

We will make a tiny connected message board with a 0.96" OLED display that can be controlled from your phone. We will use the IFTTT "DO" app to set and clear the reminder so that no extra hardware will be required besides the OLED display. In addition to the reminder, our tiny message board can display 3 other lines, which we will use to display the daily weather temperature forecast and a surf report, whic ...
