Hi, Below is BOM and timeline proposal BOM items includes 1. ESP8266 2. YF-S201 3. Solenoid volve 4. Rechargeable battery 5. Battery holder or clips 6. Solar panel 7. PCB (Battery charging circuit, MCU interface circuit, LDO Section, Voltage Level Shifter for YF-S201 or simple resistor divider) 8. Source Code Timeline: Overall 24days 1. Procurement 1: 4 days (parallel activity, effective 1day) 2. Component Selection & Schematic Design: 4 days 3. Source code 1: starts after procurement 1, uses eval boards to begin, continues till source code 2. 4. Schematic Review: 1day 5. Procurement 2 (only components for PCB): 5days (parallel activity after schematic, effective 1day) 6. Layout: 4days 7. PCB & geber review: 1day 8. Assembly and testing (only hardware bring up): 2days 9. Source code 2: 5days 10. Intermediate customer review: 4days, this is subject to customer (BOM review, schematic review, layout review, source code review) Deliverable: same as mentioned in customer project description. Note: There are few activities which are not listed eg derating, failure modes, esd protection etc.,will also be done to make this product robust Looking forward to take this project and work with you! Regards, Pradeep
