Find good hardware for NB-IoT #6

The RAK Wireless Link.One is almost perfect for orienteering:

IP65 rated, waterproof enough for orienteering
NB-IoT modem: low electricity consumption, long range (also in the forest)
Cost $94 (plus shipping and tolls)
Weight below 300 grams.
Small, slightly bigger than the old BSF7 Sportident units.

Unfortunately, the second UART port is not accessible for use with Sportident's SRR.

Investigate the following:

Can SRR's serial output be easily connected to the I2C bus available on the device? Does it require another microcontroller consuming a lot of energy?
Use RAK's bigger enclosure and RAK19001 dual IO board. Total cost with the BG77 modem, RAK4631 and IO module is around $114.
