The M1W module is an AIOT module designed based on the intelligent computing chip K210 (RISC-V architecture). The main control chip has a built-in 64-bit dual-core high-performance low-power processor.Each core has a floating point unit (FPU), a convolution artificial neural network hardware accelerator (KPU) and a fast Fourier transform accelerator (), equipped with Field Programmable IO Array (FPIOA), supports a of mainstream AI programming frameworks. The M1W module has a built-in ESP8285WiFi chip with standard 802.11b/g protocol, which allows the module to network.Different batches, product appearance and color may be different, does not affect the useColor: silverMaterial: Metal+PCBPackage Contents:1 x ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
