Hello,


I am preparing a crowdfunding project and would like to check PCBA feasibility.


Project details:

- Quantity: 300 units

- Target shipping: within 1 month after order

- PCB: 2-layer, about 40mm x 40mm


Components:

- FPC connector (0.5mm pitch)

- Battery connector (JST type)

- A few passive components

- ESP32-C3 module (Seeed Studio XIAO ESP32-C3)


About the ESP32-C3 module:

We are considering two options:

1) Do not populate the XIAO module (DNP), we assemble it manually

2) PCBA with customer-supplied XIAO modules


Questions:

1) Is PCBA for 300 units possible within 1 month?

2) Which option do you recommend for the ESP32-C3 module?

3) Estimated PCB fabrication lead time?

4) Estimated PCBA lead time?


Thank you.
