After the STM32L151, I am now designing a board for STM32L052. Following are some notes about ST application notes I read to design an board.
What can you do on a rainy evening when you go to your hackerspace?
Take a NoteRF V2 PCB, a GPS, a battery, and you can make a LoRaWAN GPS tracker!
The new version of my NoteRF project, its features are:
- New radio footprint for RFM69 (FSK/OOK) or RFM95: LoRaWAN !
- Mosfet to switch off sensors or control actuators
- Edge connector for external antenna
- Mounting slot for 3 mm screws
- Fits on a breadboard
- 3.3V regulator
