Every part in the assembly plan below is priced here. Boards include the sensor board and one connection board each, so connection boards add nothing. One injector board per power group plus a power break between neighbouring groups, and power groups don't span rows. At 10+ units the bulk per-unit rate applies to the full quantity.
Assembly plan
2 rows of 6, so 12 modules in 4 power groups and 2 signal chains.
- Power group, up to 5 modules and 3 A
- Injector board, 12 V in, feeding both directions
- Power break, 12 V cut, ground and signal through
- Connection board
- Signal chain, one WiFi client per row
| You need | Count | Why |
|---|---|---|
| Modules | 12 | 2 × 6 |
| Controller + sensor boards | 12 | one per module |
| Flap sets | 12 | one per module |
| Injector boards | 4 | one per power group, sitting after the group's first module and feeding 12 V both ways |
| Power break boards | 2 | one at each boundary between two power groups |
| Connection boards | 4 | every remaining junction (one ships with each controller board) |
| WiFi clients | 2 | the first module of each row carries the whole chain |
Worst case draw is 6.0 A at 500 mA per module, spread across 4 groups of at most 3 A. The modules alone weigh about 4.8 kg. See Connector Boards for what each board does and Planning an Installation for mounting and load.
