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.
