To get a 14s setup running with relay board you would need:
1 Main board (Order from JLCPCB)
1 Wemos mini
1 Programmer
14 slave/monitor modules (Order from JLCPCB)
14 Attiny841 microcontrollers
50 connectors (3 extra)
couple of pin male and female headers. I recommend getting both single row and dual row.
