6 Settle parts and cost

After this step you know that every part can be bought and what the boards will cost.

What you do

Wait a minute. Claude asks JLCPCB about every part it would place, with edakit stock, and prices the order:

$ edakit cost
board main, 44 × 44 mm: Economic PCBA ([release] assembly.sides top: one side)
…
  board main                                         20.65 USD
  as Standard:                                       50.23 USD (fees 38.93, parts 0.60)

What you are asked

Only where a part is a problem: out of stock, or of a class that makes the assembly dearer. Claude names the ways out: another part, a dearer assembly, or the part soldered by you.

What you decide

  • Who solders what. A part you solder yourself leaves the list for the assembler, and edakit order writes it apart:
$ edakit order
bom_main.csv: 3 lines for the assembler (5 boards)
cart_lcsc.csv: 1 line, C70377 x 5
hand_assembly.md: 1 part by hand, 0 items off the board
  • The quantity, and the shops you buy from besides LCSC.
  • Whether the cost fits your budget.

What you have

hardware/stock.json, what the shop had on the day it was asked. It ages, and the checks ask for a fresh one before an order. Next: Draw and hand over.
