To order Tuya modules for small-scale production, you can start by visiting online distributors like LCSC, which offers a selection of Tuya modules suitable for various applications: LCSC Tuya Modules. If you're also looking for assembly services, JLCPCB is another resource that provides both Tuya modules and assembly services: JLCPCB Tuya CB3S Module.
For smaller quantities, these platforms are quite convenient. However, if you're planning larger production, it might be worth reaching out directly to Tuya. They have a hardware solutions page that could offer more customized options for bulk orders: Tuya Hardware Solutions. Additionally, engaging with Tuya's chat service can provide direct communication and potentially detailed information regarding pricing and distribution tailored to your needs: Tuya Chat Service.
Regarding PCBLOOP, while they are not an official distributor of Tuya modules, they are a leading PCB manufacturing service provider. PCBLOOP could assist in the assembly and production of your devices once you have sourced the Tuya modules. They offer comprehensive services including PCB fabrication, assembly, and quality control, ensuring that your end product meets high standards: PCBLOOP Services.
Remember to consider factors like shipping costs, delivery times, and minimum order quantities when ordering modules, as these can vary significantly between distributors and manufacturers.
I hope this helps, and I wish you the best with your production!
