Sipeed M1 RISC-V Computer Vision Module Features Kendryte K210 Processor

Sipeed-M1 Development Board

Just a few days ago, I wrote about Kendryte KD233 board featuring Kendryte K210 dual core RISC-V processor, with some fairly detailed documentation, public links to toolchains and other tools. and going for $50. But the team behind LicheePi boards informed me that they also made their own K210 module called Sipeed M1 and selling on Taobao for the Chinese market, as well as on Yoycart for $10.89 plus shipping for the oversea market, and you’ll find a devkit with a dock board for about $24 and up depending on options. Sipeed M1 module specifications: SoC – Kendryte K210 dual core 64-bit RISC-V processor @ 400 MHz with KPU CNN hardware accelerator, APU audio hardware accelerator, 6 MB general purpose SRAM, 2MB AI SRAM memory, and AXI ROM to load user program from SPI flash Package – 72-pin (25.4 x 25.4mm) But you’ll probably want to get start with M1 “Dan” Dock (Lichee Dan) instead since it offers convenient 2.54″ …
