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 unit (FPU), a convolution artificial neural network hardware accelerator (KPU) and a fast Fourier transform accelerator (), equipped with Field Programmable IO (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 easily network. Different batches, product appearance and color may be different, does not affect the use Color: silver Material: Metal+PCB Package Contents: 1 x Module Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
