price optimizations
The current component price range is about 50-60€ per board (when buying for 10 pbc's). Not problematic for the prototype board, but we should optimize it.
This is a list of the most expensive parts of the board (based on the discounts you get when you buy for about 10 boards):
| Component | price per board | description |
|---|---|---|
| AS5047D | 8,19€ | encoder |
| IPD079N06L3 | 5,90€ | motor driver mosfets |
| ATSAMD21G18A | 4,78€ | controller |
| A4955GLPTR | 2,84€ | motor controller |
| RB162MM-60CT | 2,11€ | schottky diodes |
| 744773122 | 1,96€ | inductor for step down |
| 10UF POLY ELCO | 1,83€ | elco for step down (very low esr) |
| TERM BLOCK 4POS | 1,67€ | step down connector |
| MCP16331T | 1,26€ | step down regulator |
those few (main) components sum up to about 30,54€ per board.
Can this software run on 328p, stm32f103, or other lower cost, more available processors?
