Looks like <$30 to buy a single unit on DigiKey with a prevailing price ~$40, but you'd probably need a reflow oven to solder the unit. $60 for an assembled boa

Looks like <$30 to buy a single unit on DigiKey with a prevailing price ~$40, but you'd probably need a reflow oven to solder the unit. $60 for an assembled board at retail. Bulk retail is closer to $20, so OP may not have been referring to negotiated wholesale volume pricing. https://octopart.com/search?q=scd40&currency=USD&specs=0 https://octopart.com/search?q=scd40&currency=USD&specs=0
