| WBS | 50k | 20k (10) | 100k | 170k |
| WBS-cont. | 12.5k (25%) | 5k (25%) | 35k (35%) | 52.5k |

| HDI = ceramic substrate | L/O = printed circuit board substrate |
*TI quoted the NRE and prototypes together. They based the estimate on 30 prototype boards. I have simplistically assumed that prototypes cost the same as production, and subtracted the cost of 30 production modules from the total to estimate the NRE.
