The BoSL nano will be a more feature enabled version of the BoSL micro while still retaining the small form factor.
Key changes from the BoSL:
- Upgrade SIM7000 to smaller nRF9160
- Remove much of the connectivity to achieve smaller profile
- Add NFC
- Make board much smaller. No more than 15 mm in width.
- Removed MS5803
A number of new components will be used in this design.
The MCU will be the SAMD21G18. The modem used will be the nRF9160. It will also incorporate NFC. The connectivity will expose 7 analog pins and 10 digital pins as well as several power pins and an I2C interface. A diode O-ring similar to that on the microBoSL utilizing the MAX40203ANS will be incorperated so that the device may be powered either via USB or battery supply.
