Here we will detail the design of the BoSLnano, a small footprint BoSL board with enhanced functionality.
Its maximum dimensions are to be no wider than 15mm.
The architecture of this board will be similar to the main BoSL board. We will use the SAMD21G as the main processor and the nRF9160 as our LTE modem.

The first question on using the SAMD21G and the nRF9160 is a question of how these will be programmed. The boot-loader for the SAMD21G will be the Arduino MRK Zero board. This is because it has a built in SD card interface and generally is the most similar to the design. The nRF9160 will be connected via UART on the hardware serial interface. Also after the NFC chip this leaves 14 I/O pins free for end user application. The split is 7 analog and 7 digital pins, all are capable of interrupts.
The SAMD21G bootloader can be installed via a SWD interface and relevant programmer. These pins will be exposed. There are multiple programmers available on the market, a specific one has not been decided yet.
